WRT54G and BT Broadband

Does anybody have any experience setting up a Linksys WRT54GS with BT Broadband?

I've connected it to the BT Voyager 205 ADSL Router that came with the Broadband package today. The ADSL router works fine (I can use it with a USB cable), but I can't seem to get the WRT54GS to work with it. After googling around a bit, I think that BT uses PPPoA, but I'm not sure. That option doesn't appear in my Linksys configuration screen. Is that a problem? Thanks in advance for any help. I'm at my wits end, thinking I was man enough to set up wifi. I was wrong.

The PPPoA is handled by the modem and isn't visible to the Linksys router. You should just have to set it to "Automatic configuration - DHCP" in the setup tab, and it will ask the modem for an IP address for itself. Then go to Status > Local Network, and see if it has.

Do you have the wi-fi set up far enough to access the setup page over it?

Response by poster: Yes, I do. I don't have an Ethernet card, so that's the only way. I tried setting up DHCP, both manually and with the help of the linksys CD, but it still doesn't seem to work.

At the moment, though, both the ADSL router and the WRT54GS are accesible through the same IP address, which means that when I'm connected to the modem, I can't access the wireless router.

Many ISPs (including mine, Bellsouth DSL) want to sell you their routers and if you get just the cable/DSL modem, it will be configured in a way so as to not work with a router of your own without some extra work on your part.

You can try this (it's what worked for me - but is probably breaking your service agreement - so do this at your own risk).

1. Remove the router from the picture for the time being and hook your computer directly to the modem.

2. Use a command prompt (or Terminal on Mac) and run telnet to the IP address of your modem.
C:\> telnet xxx.xx.xx.xxx

3. If you have to log in, you may be able to find a default password for your modem on Google or by using the one given to you by the provider.

4. Look through the menus for an option that will allow the DSL modem to work in "bridge" mode. This essentially passes the data straight from the modem to the router. Welding them together, in a sense.

5. If you have to use PPoA, you may need to set your username and password in a modem menu as well so that it will be connected at all times. Then, you won't need to do anything on your router other than set it for DHCP (or static, depending on your provider/plan).

6. After that, hook up the router and you should be in business.

I think this will get you started. If you need more help you should at least of some good search terms to look for.

On the local network status page I mentioned, does the router have an IP address?

(remember it needs to have two, one for the wi-fi network and one for the local network between it and the modem)

Response by poster: Thank you for all your help. After screwing around with various settings in both the wireless router and the ADSL router, I finally unplugged the cable from the 'Internet' port and plugged it in to one of the ordinary network ports. Bingo. Thank you, anyway. I've learnt quite a bit more about how these things work, today. Does anybody know of good websites for learning more about this stuff? Would you recommend getting another firmware for my router?
