Greetings ,

I have been experiencing difficulties connecting my Linksys WRT54GL router to a Baudtec router provided by my ISP . The scenario i want to implement is connect the Baudtec router to the DSL line and then connect one of the 4 Lan Ports of this router to the WRT54GL  , so that any wireless client ( mainly and if possible wired

clients  ) that connects to the WRT54GL will be able to access the internet .

All am certain at this point are :

1. The Baudtec router connects without problem to the ADSL line

2. Any client both wired and wireless ones that connects to him ( the Baudtec router ) can obtain an IP Address ( through DHCP ) can access the internet .  

3. The Ethernet cable that connects the Baudtec router and the WRT54GL is working correctly .

So basically your issue is NAT behind NAT, as you are trying to connect 2 routers to each other. As your Baudtec router is already configured and you are able to go online, So you need to connect the Linksys Router to Baudtec router from any LAN port to Linksys Router Internet Port. Then you need to login to the linksys router setup page, and change the Local IP address of linksys router. As your Baudtec Router Default IP is 192.168.1.1, and the Linksys Router IP address is also 192.168.1.1, Then you need to change the LAN IP of Linksys router to 192.168.2.1 and click on Save settings. Once the settings are sucessful you need to Power cycle your network, and check if you are Online.

I have to use the Internet port or any port of the other 4 ones ? . You see when i failled to connect the baudtec router i took it at home and test it with my router a Linksys WAG200G . Since the WAG200G had an IP of 192.168.1.10 all i had to do is hardware reset the WRT54GL connect one of the 4 ports to one of the 4 ports of my Linksys WAG200G and everything worked like a charm , which is kind of confusing as to whether i have to use the Internet port or 1 of the 4 ports of the Switch . Tell me this also if u can , if  i connect the phone line to the internet port of the WRT54GL ( in other words connecting directly the WRT54GL without anything else directly to the phone line )  will it manage to synchronize with the DSL line and give me the possibility to connect to the internet ( ok i will provide the necessary info on the Basic Setup ) ?

The easiest method IMO (although the most wasteful as you have an easily modifiable router) is to disable the DHCP server and NAT functionality on the WRT54GL. You can then just use it as a wireless and wired hub. Plug in any of the local ports on the GL to the DSL router and your done.

Before you do that though:

Check what it's assigning for a subnet on the DSL router, cmd in run, ipconfig. This will show you your local IP address on the computer, if it's 192.168.1.xxx, then your on the usually defaulted subnet and just set the router's IP to something in that range that's not in use already(such as .1)so you can access it should you wish to change anything on it later. This will be in the basic settings section to alter.

Ok. Understood what happens in that case ( if i disable DHCP and NAT and in that way cripple the GL) . In case though that i don't want to follow that path and  try to implement the former solution ( NAT behind NAT .... ) if my understanding is correct i simple assign the GL a different subnet ( say 192.168.2.1) and leave the DHCP and NAT enabled . In this case do i have to say to NAT that it should translate all the 192.168.2.x to 192.168.1.x ? will it do it automatically , or it isn't needed ?

[Klatch]

When you change the LAN IP of your router i.e 192.168.2.1, leave the DHCP and NAT as it is dont make any changes, it will automaticaly translate and you will be able to go online.

Connect the Ethernet Cable from your Old router Port No.1 to GL router Internet Router. 

Please access the setup page of the router by launching an Internet Explorer and type on the address bar, 192.168.1.1 and press enter. When it prompts for the username and password, leave the username field empty and provide password as “admin "" all in lower cases and then Click on ok. On the main setup page the ""Internet Connection Type"" should be
on ""Obtain IP Automatically - DHCP “. Change the Local ip address to 192.168.2.1. Then click on “Save settings”. After close this page. Now turn OFF the power of the router and the modem, after 10 seconds turn ON your modem first and then router. Now try to get online wired.

Klatch , thanks for the detailed explanation

Klatch , in the solution that u describe in ur last post apparently u leave the SSID as it is by default ( in other words )  linksys which is different than the SSID of the Baudtec . Do i have to change the SSID in order to match the SSID of the Baudtec or i can leave it as it is ?

[Klatch · Accepted solution]

Well you need to change the SSID of WRT54GL, It should be Different from Baudtec SSID. If you wish to Secure your WRT54GL network you can do that. SSID should be different for both the routers, but you can keep the same security on both the routers, so it will be easy for you to remember the Wireless security password. Here are some setps, which you can set on your wireless router.

Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.2.1
Leave username blank & in password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
-Here select manual configuration...Wireless Network mode should be mixed...
-Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...

- Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -

Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bits.Leave the passphrase blank, don't type in anything...Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...

                                                                       OR
 
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select AES...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone.

NOTE : Passphrase should be more that 8 characters...

NOTE : Either you can Select WEP or WPA security on your Router.

 
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

It worked within a minute . Thank you for your time .
