无线网络设置问题

zephyr

研究室分配给俺一个地址，但是笔记本有两台，感觉总是不方便。

网络上淘来一个buffalo wla2-G54C air station, 想当然的设置了下。

笔记本，itouch都能找到设定好的无线网络，可是总是出现被限制的连接的图标，不能分配ip（黄色感叹号），当然也无法上网。

估计还是路由没有设置好，但是日文的设置界面，片假名的标记看得头晕，发点狠刷了固件到dd-wrt 2.4。

界面倒是变成英文了，好像还可以选择语言（好像不能断电，一断电所有的设置都要从来，语言也是）。

想当然的设置了下，笔记本，itouch都可以找到无线网络并且分配到地址，

但是TMD不不能打开网页，看样子是学校给的那个地址填得不是地方。

另外，选择项目太多，是在是看得眼花，有没有兄弟能够给个简明教程，谢谢了。

简单来说，我有一个固定的ip地址，但是我要把这个地址写到无线路由中去，以方面其他电脑上网。

用的DD WRT2.4，具体该怎么弄？

如果只给你分配了一个地址，那就要设定你的无线为路由，而不仅仅是交换，如果有mac限制，那需要进一步设置...

zephyr

mac限制都解决了，关键是比较疑惑这个玩意有没有路由功能，管理页面全是片假名看得头晕。

和另一个带路由的apple air mac比较了下，管理页面好像是有很多不一样的地方。

存档参考文件


Router: Buffalo WBR2-G54S (*125mbps Highspeed Cable/DSL Router)
Original Firmware Ver.: V2.30
DD-WRT Firmware Ver.: dd-wrt.v23_generic (Standard) SP2
Cost: $29.50 CAD (www.infonec.com)

DD-WRT Installation:

There are a couple of ways of doing this, you can either use the router's HTTP firmware update utility or tftp it. I'll cover both since you might need to TFTP the firmware if you brick your router.

HTTP Installation:

What you'll need:
- dd-wrt.v23_generic.bin (the stanrdard version)
- ddadder (its a utility that adds a hex header to the bin file)
- CAT5 RJ45 cable (any length, short the better though)
- Windows XP SP2

Place both files into your directory of choice (its best to put them on your desktop). Then before you start, click on start > run > (type) cmd

Then run the ddadder utility on the bin file you downloaded:

ddadder dd-wrt.v23_generic.bin wbr2-g54s

It'll produce a file that says dd-wrt.wbr2-g54s.bin (or something like that). Now connect your computer to the router using the RJ45 cable and plug in the power for the router.

Don't use firefox, it has been known to cause problems with the firmware

Go the the administration section and make sure you set the username and password to: root : admin . This is just a fail safe to make sure that you don't encounter any problems after the flash. Some users can't access the router using the default username : password after flashing to dd-wrt v23 sp2.

Now goto the firmware update section and select the bin that you modded earlier with the ddadder program. The whole firmware update process should take a couple of minutes. Once its done, unplug the power and then power it up again. You should be able to access the router @: 192.168.11.1

At this point, you should be able to access the control panel for dd-wrt with the username and password of : root : admin. At this point you should be ready to go.

TFTP method:

Get into the HTTP administration area of your router. Go the the administration section and make sure you set the username and password to: root : admin . This is just a fail safe to make sure that you don't encounter any problems after the flash. Some users can't access the router using the default username : password after flashing to dd-wrt v23 sp2.

Click on Start > Control Panel > Network Connections > Local Area Connection> Properties > Internet Protocols (TCP/IP)

Now instead of obtaining the IP address, click on the button that allows you to manually obtain the IP address. Change it to: 192.168.11.2 (192.168.11.1 is used by the router). click on OK and then on OK for the Properties again. The address should now be applied.

Now goto Start > Run > cmd

the defailt directory should be the user's my documents folder. type: "cd Dekstop".

Back on the Windows GUI Dekstop, make sure the dd-wrt.v23_generic.bin is moved onto the dekstop display.

Plug the RJ45 cable into the router, but don't plug in the power to the router yet!!

Go back to the cmd prompt window and type: "tftp -i 192.168.11.1 PUT dd-wrt.v23_generic.bin" don't press enter yet

*Special note:
- To get the tftp process working, you have to plug into the power and then as soon at the diagnostics light turns on red, hit enter (within 1-2 seconds of having plugged in the power). The transfer of the file will take approximately 2-3 minutes don't interrupt the file transfer process!!

If all goes according to plan, you get a reply prompt saying the file was successfully copied over and the size file. If it failed to copy over, you'll get a prompt saying "time out".

The default username / password should be: root : admin

Once the tftp process is successfully copied over, you should be able to access the control panel via internet explorer: 192.168.11.1


Trouble shooting
Some people might have flashed their routers with newer versions or the mini versions and think that they have bricked their units. This is actually not the case, you can still do the TFTP method to reflash the older dd-wrt.v23_generic.bin back onto the router

If you flashed the router with the mini version of dd-wrt, don't use Lan port 1, try 3 or 4. I personally used port 3 to flash the router when I tried the mini version of SP2. Some people recommend that you try out the SP3 or SP4 beta versions, but they don't seem to work too well. I personally recommend using the dd-wrt standard generic SP2 version, it works fine for me and doesn't seem to require too many modifcations in the control panel.

Sometimes after a flash people have issues with accessing the control panel because the username : password don't seem to work. One way to deal with is to do a factory reset via tha button at the back of the router (hold and press for about 5 seconds).


Anyways hope this helps someone out, I had to figure this out on my own because there isnt' a specific guide for my model.

管理页面弄成满屏幕的英文。。。路由是有了，还是不会设置。。。晕。

老猫

DD-WRT 好像有中文固件的吧……

zephyr

看图，这里该怎么写？？？？？？？？？？？

照猫画虎。。。好像都有问题。。。ip是有了。不能访问网络了

上面的好像设置不正确。。。学校给的地址到底应该写在哪里？？？

gooogle

怎么设置的呢

zephyr

7楼的那个页面最开始的地方，有个下拉菜单，选择静态地址，把固定地址填进去就好了。

用了一段时间，发现还是有问题，每次登录到管理页面的时候，所有的设置就全丢了，怀疑有硬件问题。
