DD-WRT固件的刷新方法

怎样刷DD-WRT固件，中文网上一般给出的是 不太规范的TFTP的方法~~

（其实对于LINKSYS的路由器，基本没必要用这个方法）

其实DD-WRT官方网站(www.dd-wrt.com)的Wiki里早就给出了全部的方法，我就当下搬运工，把它搬过来~~

后面的内容转自：http://www.dd-wrt.com/wiki/index.php/Main_Page

DD-WRT给出了3种刷新固件的方法：

1.基于WEB图形界面的刷新方法（就是用路由器管理界面里自带的刷新）

2.基于TFTP的刷新方法

3.基于命令行的刷新方法

原文有的文章只有英文，但还是比较简单。

以上所列的多数无线路由器都拥有至少4MB的flash容量，所有的WRT54GS v4.0版本之前的型号都拥有8MB的flash容量，而也有部分路由器(包括WRT54G和WRT54GS的v5.0型号)仅有2MB的flash。值得注意的是，DD-WRT的完整版("full vision"; )和迷你版("mini vision"; )的安装都需要4MB的flash;而微型版("micro vision"; )需要2MB来安装。

虽然许多其他品牌或其他型号的路由器已经由论坛中的BrainSlayer和其他人提到可以被支持，但是我并不确定是否所有已存在并可用的固件可以在这些型号上能正常启动，您可以直接向BrainSlayer询问详情，或者您也可以去获取一份源代码并自己编译，如果有人能对这些进行确认并能将其继续开发下去将最好不过。

设备推荐

最便宜的100%兼容的无线路由器: Buffalo WHR G54s

最佳的100%兼容的无线路由器: Asus WL 500G Deluxe

最具性价比的100%兼容的无线路由器: Buffalo WHR G54s

最佳性能、兼容的无线路由器: 具有266Mhz处理器的WRTSL54GS和华硕WL500G Premium，具有266Mhz处理器，8MB flash rom和64MB内存的Buffalo WZR-RS-G54，需要注意的是，如果你想将路由器用于双/多型广域网路由模式，请在购买之前搜索足够的信息，以WZR-RS-G54为例，由于其交换芯片的原因，它并能不支持DUAL WAN

刷写固件注意事项

不正确的固件刷新步骤将损坏您的路由器!

请不要使用https连接来刷新或备份路由器固件!

固件的刷新和升级应该以有线连接的方式来完成.

利用无线连接刷新可能会由于先天的不稳定性而导致路由器损坏.

请关掉您的杀毒软件，不必要的病毒检测将会打断固件向路由器的上传.

请关掉所有您系统中的无线适配器以保证是通过有线网来进行固件的上传!

在步骤2到步骤5的过程中您并不需要对因特网的连接.

我们建议您在硬盘中保存本网页以及关于如何从损坏的固件中恢复的网页，这将有助于在出现错误时使您在脱机情况下回顾所需的信息.

使用TFTP方式刷写固件

使用TFTP并不一定被认为是刷新固件唯一的标准方式，除非您被明确告知您必须使用这一方式(比如在您所拥有型号的刷新说明中)

通常情况下您只需使用基于图形界面(GUI)的刷新方式：GUI方式适用于任何标准情况，请参照相关部分以获得详细信息

使用网页界面刷写固件

[注释：我并不能区分本步骤具体适用于DD-WRT GUI或者Linksys GUI，但为了能够修正错误我必须了解这一点-- Jgoldberg 03:29，1 May 2006 (CEST)]

未使用Linksys原装固件的用户请注意：您不能使用TFTP方式来上传非官方固件！请将您的固件刷回官方版本，然后再按照下面的方法进行操作。

1) 下载固件

下载最新版稳定的发布 [1] (http://www.dd-wrt.com/)

阅读升级日志和下载页中的其他信息，它们通常包含非常重要的说明!

注意: 在从Linksys原装固件升级时请选用mini版本的DD-WRT!

如果您下载的是.zip型文件，请先将其解压缩.

通过将您所下载的固件的MD5值与官方公布的MD5值进行对比可判断该固件在下载过程中是否保持完好.

2)恢复到出厂设置

2a) 通过网页图形界面将路由器恢复到出厂设置

如果您忘记了其IP地址或者登陆密码，跳到步骤2b.

登陆到路由器的图形界面。在浏览器里输入路由器的ip地址(通常为192.168.1.1).

您将被提示输入用户名和密码。用户名可以忽略(在2006年二月28日之后的版本中，用户名为root)，输入密码之后(初始密码为admin)您将登陆到路由器的管理界面.

选择"Administration"选项卡.

点击"Factory Defaults" 子项.

选择"yes".

点击"Save Settings"按钮.

在新开页中，选择"continue".

2b) 使用复位按钮将路由器恢复到出厂设置

按住位于路由器背面的复位按钮并保持30秒将清除路由器的NVRAM，所有的设置将被清除，并且用户名和密码将恢复到原始的root/admin.

3) 上传固件!

重要提示！！！：在路由器被刷写新固件和在这之后的重新启动的过程中请不要试图中止刷新，不要在这期间关闭电脑，关闭浏览器或者关掉路由器的电源。

使用IE浏览器而不是firefox，尤其是在上传固件的过程中。因为firefox在刷新Linksys固件时会有很多不兼容的现象发生(尽管这对一个linux用户来说使用微软的IE会给您带来极大的不情愿).

再一次登陆到路由器的网页管理界面.

选择"Administration"选项卡

择"Firmware Upgrade"子项.

点击"No reset"按钮，(No reset仅仅是相对于我来说，您选择"Firmwar Default"会更适合)!).

点击"Browse"按钮，选择在步骤一中解压出DD-WRT的*_generic.bin文件.

点击"Upgrade"按钮.

路由器将会花几分钟的时间用来上传固件和进行刷新过程，然后会自动重启.

在等待五分钟之后，点击"Continue"将会打开一个新的界面,

如果刷新成功，此时您将登陆到DD-WRT的图形界面中.

Possible errors [ 可能出现的错误 ]

If the router says "Upload are failed", you could have been using the wrong .bin file, check this first. (This happens if you for example use a *wrt54g.bin file in stead of the generic.bin file when flashing through the web interface). Or you just have to give up. Your router quite likely does not support DD-WRT. [ 如果路由器出现"Uploade are faild"的提示信息，你首先应该检查是否用了错误的.bin文件进行升级(这出现在 比如你用*wrt54g.bin而不是*generic.bin文件 通过WEB界面更新固件的情况下) ；或者你刚才尝试放弃升级固件；或你的路由器很可能不支持DD-WRT]

4) 再一次恢复到出厂设置

Do this only after you have confirmed that the firmware upgrade is working. At this point you may have temporary problems using Web Interface, so just ping your router.[ 只有当你确定固件已更新成功，再做这步。这时，你使用WEB界面可能出现临时的问题，所以仅ping下你的路由器即可。]

For V23 SP2[适用于V23 SP2]: Please do a hard reset: While holding down the reset button, plug in the power cord. Hold the reset button for 30 seconds. See also Reset And Reboot.[请做一次硬重启：拔下电源插头，按下复位键，再插上电源插头并保持按住复位键30秒。请参阅Reset And Reboot。]

This is at first because SP2 uses encrypted password storage inside nvram. You are unable to login using root/admin before you reset. Please take this step serious!!! [ 因为SP2在nvram内部使用了加密的密码存储，在硬重启之前，你不能用root/admin登录路由器。]

Previous versions[适用于以前的版本]: Press and hold the reset button on the back of the router for 30 seconds. See also Reset And Reboot. [ 按住路由器背面的复位键30秒。]

5) 尽情使用您的无线路由器

我们推荐您将"Adninistration"选项卡中的"Boot Wait"值设置为"enable"，这将在将来对您的路由器从不正确的刷新中恢复有很大帮助，在v23或更高的版本中，"Boot Wait"值默认为"enabled".

6) 出现了错误?

如果您的路由器不能重新启动(如电源灯不亮，不能打开网页界面等等)，您需要修复受损固件，这里是一个step by step的恢复指南(英文) (http://www.dd-wrt.com/wiki/index.php/Recover_from_a_Bad_Flash), 或者使用论坛搜索功能会带给您更多的额外信息。forum search (http://forum.bsr-clan.de/search.php).

使用命令行方式刷写固件(使用telnet/SSH)

1) 使用telnet或者ssh登陆 (http://www.dd-wrt.com/wiki/index.php/Telnet/SSH_and_the_Command_Line) WRT

2) 使用wget (http://www.cbi.pku.edu.cn/Doc/CS/wget/man.wget.html) 或者 scp (http://winscp.net/)下载dd-wrt.v2*_generic.bin到/tmp文件夹

3) (可选项) 对比下载文件与源文件的md5值 (http://www.research.att.com/~gsf/man/man1/md5sum.html)

4) 输入

write /tmp/dd-wrt.v2*_generic.bin linux

5) 请稍等...

6) 重启路由器

7) (可选项) 通过网页方式（推荐）恢复路由出厂设置 ###NextPage###

对WRT54Gv4/WRT54GL的刷新

仅DD-WRT的v23或者更高的版本能支持WRT54Gv4，此款路由器不支持从Linksys原始固件刷新到standard和voip版本的DD-WRT(Linksys限制了固件大小不能超过3MB)，因此，最初只能刷写MINI版的DD-WRT。您可以在MINI版安装成功后再升级到standard或voip版的DD-WRT，在使用网页界面刷新的过程中，请使用*_generic.bin类型的文件，在无法使用GUI界面的情况下您需要使用tftp上传special *_wrt54g.bin 类型的文件，并且确保每次刷新之前和之后都需要将路由器恢复到出厂设置。

[Comment added 26/06/06 by Elvey]] Firefox works fine when flashing and using this router. I've flashed and set up 2 WRT54GL's, with Firefox, and had no problems. I've no idea what incompatibilities others are talking about (mentioned below).

[Comment added 10/08/06 by blkadder]]

I'd like to second the trouble-free Firefox experience. I used Firefox 1.5.0.4 on a SUSE 10.1 machine with no problem.

[Comment added 24/06/06 by msc_buff]] I ran into serious port forward problems with my GL v1.1. I reread the flash procedure here and used the '30 second reset' with the button instead of the WebGUI and it fixed my problem. Not sure what the difference between a soft reset and a hard reset is but I will stick with what worked for me.

对WRT54GSv4的刷新

如上所述由于Linksys的3MB固件容量限制，WRT54GSv4不能从Linksys原始固件刷新到std或者voip版本的DD-WRT，您只能使用MINI版来进行首次刷写，否则将会导致刷新失败，成功刷新MINI版之后您即可以通过网页界面升级至std或者voip版本了。有趣的是，在用"v4mini"刷写了4台WRTGSv4之后，我却发现必须使用"v4mini"来刷新其他非v4版的WRT54GS，否则将会以"Upgrade are failed"失败而告终，请确保在每次刷新前后都要进行恢复出厂设置，至少对现在的固件(27.10.05-dd-wrt.v23.beta2)来说是非常必要的。

[Comment added 11/01/06 by bigbloke of cownet.org] Today I purchased a 'GS V4 not having read this note previously. It flashed V23 standard perfectly first time from the specific file (dd-wrt.v23_wrt54gsv4.bin) therefore there may be some additional factors influencing this) - I hope this is useful feedback

[Comment added 12/01/06 by Mart] I just purchased a GS V4 too. After reading bigbloke's note, i decided to try skip the warning and directly flash V23 VPN from the (dd-wrt.v23_vpn_generic.bin) file without any problems too. I simply followed the "right way to flash" instructions step by step. Looks like the warning mentioned above does not apply with this version.

[Comment added 18/01/06 by Macks] I can second the above, just flashed a GSv4 from Linksys original and used dd-wrt.v23_vpn_wrt54gsv4.bin without problems, directly without going via the mini.

[Comment added 22/01/06 by JD] I can confirm the statement from Macks. Two days ago I bought also a 'GS v4' and I flashed it with the v23 standard without problems (directly without going via the mini)

[Comment added 19/02/06 by markusk] and i did it that way as well and after that got the weirdest behaviour of a router i've ever seen, mainly giving something like unstable wan-connection by going with high traffic over the router (be it via bittorrent, icq-filetransfers and similar).. unfortunately reflashing with mini and then a "big" one didn't help at all..

[Comment added 28/02/06 by mfb] Like Macks I flashed my 'GS v4' with v23 vpn direct, without mini first - working fine, no problems.

[Comment added 05/03/06 by PhoneBoy] On my WRT54GSv3, I found that the device wouldn't take ANY firmware unless I reset it using the button rather than just factory reset from the web interface. Word of warning.

[Comment added 10/03/06 by JoE] At the time of this writing, the current version of Mozilla Firefox will cause your installation to fail when trying to upgrade firmware (dd-wrt.v23_mini_wrt54g.bin, dd-wrt.v23_generic.bin, dd-wrt.v23_wrt54g.bin) using the web interface. I used the current version of Internet Explorer with no problems. Additionally, if your power button keeps flashing and/or you cannot reach/ping 192.168.1.1 after a reset, unplug and plug in the power cord real quick. Wait a few seconds and then everything is hunky dory.

[Comment added 09/04/06 by zonk] I also can confirm the above statements of flashing two fresh bought WRT54GS v4 routers using the vpn version (v23) instead of the mini version. I used Firefox 1.5 and Opera 7.5 without any failed message. Both routers run stable.

[Comment added 04/06/06 by Yusuf Motiwala (http://www.motiwala.com)] I too can confirm that it can be upgraded directly to standard version. Even after reading this, I experimented upgrading my WRT54GSv4 directly with v23 SP1 standard image without any problem. May be stated limitation is firmware version dependent. At the time of upgrade, my linksys stock firmware version was 1.5.2.

[Comment added 05/07/06 by Kizane] DD-WRT v23 IE7 Beta 2 Error! I noticed some weird error while managing a WRT54GSv4 with DD-WRT V23 via IE7b2. For some reason, it cuts off the top of the area where all the settings are. I opened the control panel with Firefox 1.5.0.4, and it has no errors. IE7b2 Screenshot (/Article//UploadFiles/200712/20071215200150423.jpg)

[Comment added 05/07/06 by Kizane] Solution to above comment. Note that I upgraded to DD-WRT v23 SP1 Final (via Firefox 1.5.0.4 with zero problems!) and the problem has vanished!

[Comment added 07/08/06 by Wayland] I found it best to start with factory settings before flashing WRT54GL for the first time

对WRT54G(S)v5的刷新

请参照对第五版WRT54G的刷新

对Buffalo WHR-G54S，WHR-HP-G54 和WZR-RS-G54的刷新

仅能使用v23 sp1及后续版本，过早的版本可能会产生错误!

为了彻底恢复到出厂设置，请按住路由器的复位按钮并保持至少30秒，然后拔下路由器电源.

使用网线将您的计算机与路由器中任意一个LAN口相连(交叉线与直连线均可).

因为Buffalo初始设置的局域网段为192.168.11.1(WZR-RS-G54为192.168.12.1)，您需要将计算机的ip地址设置在其网段内并填好正确的子网掩码，(例如 192.168.11.2， 掩码 255.255.255.0 对于WZR-RS-G54设置成 192.168.12.2， 掩码 255.255.255.0 )，须要说明的是您需要将其设置成静态IP，在使用tftp的过程中静态IP是非常必要的，在子网中即使使用正确的动态ip也不会使tftp正常工作。在windows xp系统中，请参照如下截图：在点击"Internet Protocol (TCP/IP)，" 之后，选择"Properties"按钮，然后填入正确ip地址，默认网关设置为空，点击"ok"。错误的设置如图:

通过 开始->运行->"cmd"打开命令行窗口.

进入包含固件文件的文件夹(：) (例如. cd C:\Documents%20and%20Settings\All%20Users\Desktop (如果固件文件在您的桌面上的话)

准备输入上传固件的TFTP命令.

输入 tftp -i 192.168.11.1 PUT (file name of firmware image) 例如: tftp -i 192.168.11.1 PUT dd-wrt.v23_generic.bin. (对于 WZR-RS-G54 使用 192.168.12.1 作为路由器地址 .) 此时先不要按下回车键.

提前阅读余下步骤以获得正确的操作顺序，正确操作的关键在于对时间的掌握.

给路由器接通电源.

所有指示灯会被点亮.

在之后的一秒钟左右，除了您计算机所连端口对应的指示灯之外所有的端口指示灯均会熄灭，马上按下回车键.

路由器的LAN指示灯经过大约6秒钟的频繁闪动之后，您将得到一个输入成功的提示，类似于：Transfer successful: 3502080 bytes in 5 seconds, 700416 bytes/s

在bridge/diagnostic指示灯熄灭之后路由器将启动DD-WRT.

此时路由器已经可用，尽管重新启动是确保正确工作的一步，但是此时已经没有必要这样做.

此时路由器将工作在192.168.1.1地址上，您需要更改计算机的IP地址到192.168.1.0段上才能对路由器进行设置(对于WB2-G54，仍然可以使用192.168.11.1进行连接并设置).

登陆的用户名为'root'，密码为'admin'.

在Linux或OS X上TFTP的使用说明

在linux或OS X系统下，首先运行tftp，并将更改为binary工作模式，然后输入"connect 192.168.11.1" 但不要立即执行，在文本编辑器或者在本网页上复制好PUT命令，当除了计算机所连接端口之外所有指示灯熄灭时迅速按下回车键，并且马上粘贴PUT命令并回车。操作命令如下例：(对于WZR-RS-G54只需将所有的192.168.11.1更改为192.168.12.1):

tftp

tftp> binary

tftp> connect 192.168.11.1

tftp> status

Connected to 192.168.11.1.

Mode: octet Verbose: off Tracing: off

Rexmt-interval: 5 seconds, Max-timeout: 25 seconds

tftp> put /path/to/dd-wrt.v23_mini_generic.bin

linux中另外一种可选tftp指令(仅需使用本部分介绍或者如上所述的命令之一，而不是二者全部):

tftp 192.168.11.1 -m binary -c put dd-wrt.v23_generic.bin

注意：OS X中内建tftp不支持此指令

在命令行中输入指令之后（不要按回车键），启动路由器，在除连接计算机的指示灯熄灭以后输入回车.

在提示中"status"会带有一些迷惑性，此时路由器此时其实是关闭的.

注意

如果您在Buffalo WHR-G54S/WHR-HP-G54/WZR-RS-G54上刷写了DD-WRT之后想刷回原厂固件，请联系BrainSlayer. (http://forum.bsr-clan.de/profile.php?mode=viewprofile&u=486)，他可以向您提供可用的原厂固件.

一个隐藏在路由器面板之后的指示灯将被激活，并会轻微地透过bridge指示灯发光，在Buffalo原始固件中此指示灯没有被用到，但在DD-WRT中它将以两秒为间隔交替闪亮.

在使用v23 sp1时，路由器将以192.168.1.1/255.255.255.0的ip地址启动

没有必要使用WRT54GS的两步法刷新，Buffalo可以一次性接受整个通用固件.

在后续的升级或恢复DD-WRT过程中，请使用网页方式进行刷新，请参照：使用网页图形界面进行刷新.

关于WHR-HP-G54的附加信息--更改主板特性标识，打开HP功能

使用telnet登陆路由器，在windows中向命令行窗口输入 telnet 192.168.1.1建立telnet连接.

用户名为root，密码为admin

输入如下命令

nvram show | grep

boardflags boardflags=0x1758

~ #

如果您得到0x1758参数，使用如下命令将其改为0x2758

nvram set boardflags=0x2758

nvram commit

reboot

为此您能够开启路由器中的HP功能，它将非常明显的提高路由器的信号强度.

此功能的设置不能够通过图形界面方式备份，每次恢复路由器设置之后请重新手动打开HP功能.

答疑

如果您遇到问题，一个连接在路由器与交换机之间的路由器可能会帮助解决问题.

如果您遇到问题，您可以通过telnet连接输入如下一条(或两条)命令来清除NVRAM:

Option 1 :

mtd erase nvram

Option 2 : (借助OpenWrt FAQ (http://wiki.openwrt.org/Faq#head-71cacf8460752af3f5771d2fae54923ded5beb9c))

cd /tmp

wget http://openwrt.inf.fh-brs.de/~nbd/nvram-clean.sh

chmod a+x

/tmp/nvram-clean.sh/tmp/nvram-clean.sh

nvram commit

您可以以WHR-G54S和您所遇到的问题为条件在论坛中搜索历史纪录.

如果您的路由器在刷新后无法工作，您可以在论坛中利用"WHR-G54S Bricked"搜索到足够的信息.

对其他Bufalo路由器的刷新

刷新您的Buffalo WBR-G54，WLA-G54，WBR2-G54，WBR2-G54S...

对贝尔金F5d7230-4的刷新

贝尔金路由器有几种版本.v1000，v1111拥有4MBflash容量，而v1444仅拥有2MB，所以对于v1444您只能使用tftp方式刷新2MB的micro版本固件。如果你的路由器是4MB的型号，您可以通过如下步骤使用网页方式刷新所有版本的固件。除非您有具体的需要，我们建议您在贝尔金路由器上使用micro版的固件以使其更好的工作.

下载最新的micro版固件（目前为止为dd-wrt.v23_micro_generic）

将路由器恢复出厂设置，并关掉路由器电源.

使用网线将您的计算机与路由器中任意一个LAN口相连.

因为路由器将以192.168.2.1地址启动，所以将计算机的ip地址设置为192.168.2.2，子网掩码255.255.255.0，默认网关为空。如需帮助，请参照Buffalo刷新步骤中相关部分.

开始->运行->"cmd"，并回车.

进入包含固件文件的文件夹,例如. cd "C:\Documents and Settings\All Users\Desktop"

输入 tftp -i 192.168.2.1 PUT (固件名称) 例如: tftp -i 192.168.2.1 PUT dd-wrt.v23_micro_generic.bin. 不要按回车键.

将路由器连接上电源.

所有指示灯会被点亮.

在之后的一秒钟左右，除了您计算机所连端口对应的指示灯之外所有的端口指示灯均会熄灭，等待1秒钟后马上按下回车键，如果您得到超时错误的提示请重试，如果您依然遇到问题请使用后面的额外方法.

路由器的LAN指示灯会闪动几秒钟，请耐心等待直到电源灯熄灭提示刷新结束，这将花费一段时间.

重启路由器.

将计算机IP地址改为自动获取，或者设置为192.168.1.1.

在浏览器中输入 192.168.1.1 进入路由器的登陆界面

用户名为root，密码为admin

尽情享用您得DD-WRT

刷新F5D7230-4的另外一种方法

如果您不愿意花费太多时间，懒得不断地重新启动路由器，您可以试用这种在我的v1444上奏效的方法:

按照上述办法执行直到将计算机ip地址设置为 192.168.2.2

登陆到linksys网站下载页.

下载BEFW11S4型无线路由器固件.

从.zip文件中解压tftp.exe程序.

启动tftp程序，将其server设置成192.168.2.1，然后将"dd-wrt.v23_micro_generic.bin"载入其传送文件部分.

将重试次数设置为20.

启动路由器.

点击tftp程序的升级按钮同时按下路由器的复位键，如果程序不能登陆到路由器进行刷新只需再次按下复位键。在刷新的过程中tftp程序会显示上传文件和成功操作的具体过程.

在我利用第一种方式进行了至少40次的不成功尝试之后，我使用这个方法在第十一次重试的时候成功的上传了固件。我不确定这个方法能不能适用于其他版本的F5D7230。经过我的切身体会，我发现在成功刷新之后贝尔金路由器的指示灯状态会有所改变，WLAN指示灯失去作用，电源灯没有问题但是在WAN口插入网线之后WAN指示灯会一直闪烁.

在经历了至少50次不成功之后我终于利用这个额外方法将我的v1444刷新成功，但都是用一个hub或者交换机连接在计算机与路由器之间的情况下刷新才能成功。我所有基于直接连接计算机与路由器的操作均以超时失败而告终，但使用hub或者交换机我竟然第一次就刷新成功。使用直接连接时之所以失败是因为当路由器重启或复位时tftp会失去连接，而当连接再次重建时，路由器却已经错过了接受固件的时机。所以如果您正遭遇刷新困难，您可以尝试在路由器和计算机之间连接一个hub或者交换机使用此种方法进行您的刷新过程。

对华硕 WL500G Deluxe的刷新

拔掉Wl500G电源.

在按住复位按钮的同时，插上路由器电源.

当电源灯开始闪烁时松开复位按钮，此时路由器进入恢复模式.

等待计算机获得IP地址.(如果DHCP打开了的话)

使用华硕recovery utility工具上传DD-WRT.trx固件.

您可以点击这里 (http://dlsvr03.asus.com/pub/ASUS/wireless/WL-500g-03/Eng_1380.zip), 下载recovery utility，或者登陆华硕网站下载最新版本.

为了防止在使用多网口时不能找到您的路由器，请封闭除了您所连接的计算机外所有网口.

升级后路由会重新启动，此时您将可以登录到路由器网页设置界面

SSD: For my new WL-500g Deluxe, the recovery utility would appear to successfully upload the firmware (v23), but then I could not get it to boot... even after waiting several minutes and power cycling. The unit would also be unresponsive to ping requests. I could always successfully reload the original Asus firmware. TFTP methods were unsuccessful altogether, as TFTP never seemed to establish contact with the router. Finally, I was able to boot DD-WRT by first flashing with OpenWRT (White Russian rc4), then using OpenWRT's firmware upload page to flash with DD-WRT.

LFR : Upgrade was done out of the box with .trx file & worked straight, no need for recovery mode

MrO: Does this also work on the WL-500g Premium? TTSherpa: Yes it does. No problen going back an forth the original FW & dd-wrt

对西门子SE505的刷新

BrainSlayer曾提到“DD-WRT v23(2005/10/27)开始提供对西门子Gigaset SE505路由器的官方支持，这意味着您将可以在此设备上使用类似于WPA2等最新特性，由于此路由器的内存限制，您不能同时使用使用这些新特性，但是相对于原始固件的最基本功能来说已经强的多了”

在对西门子Gigaset SE505刷新的过程中，您只能使用tftp方式上传dd-wrt.v23_mini_generic.bin文件到路由器的地址上(默认192.168.2.1)，因为西门子的初始设置与Linksys/dd-wrt的不同,所以您需要在刷新之后需要检查各种配置的细节.

(摘自BrainSlayer在hwsupport.txt中的说明)

在 changelog.txt (http://dd-wrt.gruftie.com/dd-wrtv2/downloads/index.php?path=dd-wrt.v23%2F&download=changelog.txt),中关于SE505的最新一条提到：SE505第二版在刷新时出现了错误 15.11.2005:

有谁能提供关于此条说明的更详细的信息或者有谁在SE505第二版上成功安装了DD-WRT么？

01.mai.2006. I successfully flashed a se505 v2(S30853-S1006-R107-3) with the v23_micro sp1_4.25.06 only the browser buttons on "administration|management" are not working. WDS with WEP is running well at the moment with 2 other WRT54 V23. Other things not tested yet.with v23sp1_04.28.06 buttons on basic-setup are not working - so no adjustment on ip possible. ddt3 at gmx dot net.

02.mai.2006. Even with v23sp1_2006 micro - 0501 buttons on "administration|management" are still not working. WPA as a AP seems not to work on my se505v2. With wrt54gl V23 it works for reference with my notebook yakumo quicklan USB54 XP-generic-setup. If you flash a new fw with tftp somtimes it apears as 192.168.0.your setup and sometimes as 192.168.1.1 an 192.168.2.1. So change your IP to a suitable subnet and search with ping. ddt3 at gmx dot net.

08.mai.2006. Firmware: DD-WRT v23 SP1-RC1 (05/07/06) micro with se505 v2(S30853-S1006-R107-3) works fine now. all the problems from 1+2.mai2006 are solved so far i see in this short time. ddt3 at gmx dot net.

09.mai.2006. update: wpa-psk and wpa2-psk ist not working with my constelation. i flashed back to the orig. siemens_de_3.02.03 fw. with this wpa-psk is running well with orig. xp setup and with yakumo setup - so seems to be a fw problem ddt3 at gmx dot net.

12.mai.2006. after updating to "dd-wrt.v23 SP1/RC2/micro" wpa-psk and wpa2-psk works with my pc! ddt3 at gmx dot net.

18.mai.2006 with DD-WRT v23 SP1 Final (05/16/06) micro (generic) it works also fine. If the se505v2 dont accept the new parameter after press the save button try to switch off the siemens for a moment and restart your browser (be sure to close all your browser windows).ddt3 at gmx dot net.

9.june.2006 will the SE515 be supported?

17.july.2006 dd-wrt.v23_micro_generic_sp2.bin (11.07.2006) works also fine and stable on se505v2 now for 3 days with pppoe in use. but it never shows full speed rate. 36 Mbps is max shown despite the wds oposite station shows 54 Mbps. to see the lease time expire count down I had to swich off "DNSMasq for DHCP" .ddt3.

WRT54G v4 Installation Tutorial

（WRT54G v4 刷新方法图文并茂教学）

原文地址：http://www.dd-wrt.com/wiki/index.php/WRT54G_v4_Installation_Tutorial

The following are the steps that I went through to get DD-WRT v23 installed on a WRT54G v4. I tried to take screenshots of each step as I went, so as not to confuse anyone. Following the instructions found at Steps_to_flash_through_Web_Interface (http://wrt-wiki.bsr-clan.de/index.php?title=DD-WRT_Docu_%28EN%29#Steps_to_flash_through_Web_Interface), I was eventually successful in getting DD-WRT installed. I will use some of the text from those instructions as well as inserting my screenshots and other encounters not mentioned in the above link.

1) Download the DD-WRT v23 firmware

You must use the mini version when upgrading from original linksys firmware!

Download the Mini Version 23 HERE (dd-wrt.v23_sp2_mini.zip ) (http://www.dd-wrt.com/dd-wrtv2/down.php?path=downloads%2Fdd-wrt.v23%20SP2%2F&download=dd-wrt.v23_sp2_mini.zip) or go to the DD-WRT downloads section at http://www.dd-wrt.com/dd-wrtv2/index.php?link=downloads

Extract the archive. Once it is downloaded and extracted from the zip archive it should look something like this:

2a) Reset through the Web Interface

if you forgot the password or IP of your router, proceed to step 2b.

From a PC connected to one of the 4 LAN ports on the router open a web browser and go to the IP of the router (default IP is 192.168.1.1).

You will be prompted for username and password. Username is not required. Enter password (default password is admin) and you should be at the Web Interface of your WRT54G v4

Click the "Administration" tab.

Click the "Factory Defaults" sub-tab.

Select "Yes".

Click the "Save Settings" button.

A warning will pop up, click "ok".

2b) Reset to factory defaults

Press and hold the reset button on the back of the router for 30 seconds. This will clear your NVRAM, the configuration and reset the password to admin.

Be aware that if your router currently has an OpenWRT firmware running on it, then using the reset button may brick your router. Research your current firmware to be safe.

3) Upgrade Firmware

Do not turn off the computer, close the web browser, or turn off the router during this process!!!!!

From a PC connected to one of the 4 LAN ports on the router open a web browser and go to the IP 192.168.1.1.

You will be prompted for username and password. Leave username blank, enter password admin. Now you should be at the Web Interface of your WRT54G v4.

Click the "Administration" tab

Click the "Firmware Upgrade" sub-tab.

Click the "Browse" button and select "dd-wrt.v23_mini_generic.bin" file you extracted in step 1.

Click the "Upgrade" button.

The router will take a few minutes to upload the file, flash the firmware, and then reset.

Here is where my experience was a bit different than the instructions said it would be. I never got success message, instead of got a failed message. This is when I started to get a bit nervous that I had bricked my brand new router! So I started reading furiously through all the documentation I could get my hands on about recovering a bricked WRT when I relaunched "192.168.1.1" and found that DD-WRT was working! Don't ask me... but the flashed seemed to have worked perfectly despite the error message I got. (注意：本文作者估计是RPWT，刷新成功却显示“失败”。这个故事告诉我们当看到“failed”时不要慌张，先登一次“192.168.1.1”，确认DD-WRT是否成功刷新。)

Additional note #1: as of version v23 SP1 (http://www.dd-wrt.com/dd-wrtv2/downloads/index.php?path=dd-wrt.v23+SP1/) the default login username/password has changed from /admin to root/admin.

Additional note #2: if you are flashing the router using Firefox, it may warn you a dozen times that some scripts are very slow, giving you the option to stop that script, or continue. You should press continue (or use alternate browser). To fix the unresponsive script issue in Firefox, navigate to about:config, then increase the integer value of dom.max_script_run_time from 5 to 20.

If flashed successfully you will now be at the DD-WRT web interface and the Router Name will be DD-WRT.

4) Reset to factory defaults AGAIN

Repeat step 2 above. Note: step 2b (the manual way of clearing the NVRAM) is recommended to make sure the radio gets the correct parameters.

5) Upgrade the Firmware to DD-WRT STD v23

It is strongly advised that you enable the "Boot Wait" option under the "Administration" tab before continueing. This will help you recover in the future should you flash your router improperly. If you use v23 or higher the "Boot Wait" option is enabled by default.

Download the STD Version 23 HERE (dd-wrt.v23_sp2_standard.zip) (http://www.dd-wrt.com/dd-wrtv2/down.php?path=downloads%2Fdd-wrt.v23%20SP2%2F&download=dd-wrt.v23_sp2_standard.zip) or go to the DD-WRT downloads section at http://www.dd-wrt.com/dd-wrtv2/index.php?link=downloads

Extract it

Click the "Administration" tab

Click the "Firmware Upgrade" sub-tab.

Hit the browse button and select dd-wrt.v23_generic.bin that you just extracted.

You should see the progress of the flash like so:

If the upgrade went well then you should see a success message. You're done!

6)Troubleshooting

If your router fails to reboot (power light doesn't stop flashing, no web interface, etc) you will need to Recover from a Bad Flash.

###NextPage###Recover from a Bad Flash

（刷新失败后的恢复）

原文地址：http://www.dd-wrt.com/wiki/index.php/Recover_from_a_Bad_Flash

So, you're afraid you've bricked your router. Don't worry, there are a number of things you can try to get your router working again before giving up and living with the fact that your router is now a paperweight.

WRT54G

The Linksys site mentions 'Management Mode' which makes it trivial to recover from bad flashing (answer id 3176 (http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/std_adp.php?p_faqid=3176&p_created=1131055153&p_sid=EUHR75mi&p_accessibility=0&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9NzQmcF9wcm9kcz0wJnBfY2F0cz0mcF9wdj0mcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9ubCZwX3NjZl9sYW5nPTEmcF9wYWdlPTEmcF9zZWFyY2hfdGV4dD1maXJtd2FyZSB3cnRnNTRn&p_li=&p_topview=1)). Here's how to do it:

Unplug the power cord from the back of the router.

Hold down the Reset button.

While holding down the Reset button, plug back in the power cord to the router.

Continue to hold the Reset button for five (5) seconds. After five (5) seconds, release the button.

Wait for about one (1) minute. Then, on a computer connected to the router, launch a web browser (for example, Internet Explorer or Mozilla Firefox).

Type in the router's IP address of http://192.168.1.1 into the Address field and press the [Enter] key.

The Management Mode - Firmware Upgrade interface should appear.

Linksys Firmware

If you cannot find a Firmware Auto-Upgrade utility at the Linksys Download Page (http://www.linksys.com/download), use a Setup Wizard (http://www.linksys.com/servlet/Satellite?childpagename=US%2FLayout&packedargs=c%3DL_Download_C2%26cid%3D1115417109974%26sku%3D1121194966438&pagename=Linksys%2FCommon%2FVisitorWrapper) as an alternative from other Linksys router (make sure to use your router's firmware).

Another tftp program is called tftp2 and is available here (this will start the download): tftp2.exe (http://www.shadowsoftware.net/shadowgameworld/downloads/tftp2.exe&pagename=Shadowsoftware)

Recovering with TFTP

If pinging 192.168.1.1 does not work, check the IP Address of your computer and make sure it is assigned an IP address in the subnet of the router IP. For simplicity sake you can assume "192.168.1.x" is good. If you do not have a good IP, the DHCP Server might not be working. So set your IP manually to something like 192.168.1.77 with 192.168.1.1 as your gateway and then try pinging the router again.

Power the router on with a continuous ping running in a command window. You should see at least some seconds, at least 2-3 pings, where it responds to ping of 192.168.1.1 address. Do this several times to be sure. If it does you have good chance of simple recovery. Especially if previous firmware set the boot_wait variable to on, the router pauses even longer than normal during bootup to accept a recovery flash. All you need to do is provide a firmware to it via TFTP during this window of time.

Prepare your PC, firmware file and TFTP software and play with the timing of powering it on and starting the TFTP session just after applying power. If you try it a number of times (at least 10) you will probably rescue the router with no fuss!

Microsoft Windows contains a TFTP (http://en.wikipedia.org/wiki/Tftp) client. With TFTP, all of the information about the transfer is specified during the initial setup; there is little client/server interaction as compared with standard FTP. To flash a router using Microsoft Windows, open a command prompt, change to the directory containing the firmware to upload (this example assumes the firmware file name is code.bin), and then enter the following command (assuming your router IP 192.168.1.1):

Warning: This command has not yet been verified. Someone with experience with this should check the command below, modify it if necessary, and remove this warning.

tftp -i 192.168.1.1 PUT code.bin code.bin

Notes: The -i specifies binary transfer mode; the two file names after the PUT command specify the SOURCE and DESTINATION file names.

If That Doesn't Work

If the Linksys-approved method does not work for you, the [WRT54G Revival Guide (http://www.linksysinfo.org/forums/showthread.php?t=47259)] includes a second technique that involves snapping open the plastic case of the router and using a small metal tool (or paper-clip) to "short" two particular "pins" on the circuit board. It is quite clear that this carries risk of permanently damaging your flash via static discharge, and should be a measure of EXTREME last resort, not the first thing to try. You can very likely recover from a bad flash WITHOUT opening the router if you have some patience with the TFTP technique.

If you do have to use the EXTREME measure #4 from the revival guide as I did here is a additional tip uncovered from this forum. Voidman forum (http://voidmain.is-a-geek.net/forums/viewtopic.php?t=760&postdays=0&postorder=asc&start=75)

I used the "earthing" technique to get the WRT54g v3.1 to respond to pings. Whenever I tried to tftp the dd-wrt firmware, it would cause the router to stop responding to pings ans just give a "timeout" error.

The solution was to first tftp an official LINKSYS firmware (WRT54G_4.30.5_US_code.bin which I renamed to "code.bin"). The router accepted it and rebooted properly. I was then able to upgrade to the latest dd-wrt v.23 SP2 through the WebGUI. This was discovered on GS v.4 which responded to unofficial firmware with "incorrect code pattern." Apparently this happens when tftp'ing to an empty flash chip.

There's also a collection of pointers and tips on how to recover from a bad flash at the external link location, but most of the information in that forum seems to have been collected into the WRT54G Revival Guide. So far this is just a starter wiki. If someone could move the important parts into this wiki, that'd be great. Probably organize it by recovery methods and list variations of each method below the method, or something.

Buffalo WHR-G54S

If you have already tried pinging the Buffalo continuously through hard and soft resets, unplugging, plugging and any combination thereof, then you will need to open up the device in order to revive it, similar in practice to the WRT54G Revival Guide Method #3 (http://www.linksysinfo.org/modules.php?name=Content&pa=showpage&pid=33).

Unplug the router, and slide off the side trim panels. One will be covering a torx screw.

Undo the screw and open up the router.

With the router unplugged, plug a patch cable into one of the 4 LAN ports on your router and plug the other end into a computer.

Configure your network card on your computer with a static IP address: IP: 192.168.11.2, NETMASK: 255.255.255.0, no gateway.

Run a the ping command in a terminal or command prompt. In Linux: "ping 192.168.11.1". In Windows "ping -t 192.168.11.1" so that it doesn't stop trying to ping after 4 pings.

Locate pin 12 on the flash memory chip. It is the 12th pin counterclockwise from the dimple in the surface of the chip. See the specs for this chip here (http://www.mxic.com.tw/QuickPlace/hq/PageLibrary48256F5500439ED0.nsf/h_CE4C9490FDF4280B48256F550043C6D8/209CFCBBF4BCCB9148257031002F02E6/$File/MX29LV320CTBver15.pdf?OpenElement).

Short this pin to ground (bare solder around antennas, screw points).

While holding the screwdriver there, plug in the power and watch your ping screen. You should see the pings starting to succeed.

Remove the screwdriver and the pings should continue.

Now use the tftp method to rewrite the firmware.
