Ok, so not strictly Linux related, but technical nonetheless, and I was using Ubuntu when I set it up 
I have a BT HomeHub (V1) which I…modified…to use the firmware for the router it was originally (a SpeedTouch 7G) so I could use it with a different ISP. This was back in June/July, and I’ve been having to boot into Vista (sad I know) to get internet access to play on Xbox Live, etc.
So I finally gave up today, and got around to trying to configure another HomeHub – this one with the BT Firmware as the repeater. After a lot of tweaking, I found the solution to be quite simple, and I found it here.
Now, I have 2 ethernet ports in my room, and my laptop hovers at around 95% all the time now, which is nice, better than the 40-68% I was getting before anyway. It also means I can have my Xbox 360 online without paying out for either a really long eth cable, or a wireless adapter for the 360 (they retail at around £60 here in the UK).
Either way, I’m happy with it, so I won’t complain 
Edit: I forgot to mention, I experimented a little after setting it up (and nearly broke it!) and I configured the 2 routers to broadcast the same (E)SSID, which seemed to be ok, and caused a little confusion initially on my laptop, but it seems to work just fine now, and my laptop automatically switches to whichever has the strongest signal

How funny, I did almost exactly the same.
Bought a couple of new homehubs off of ebay for £6 a pop, set one up for broadband, turned off dhcp on the second and used WDS to connect it to the first. They use different SSIDs but it works for me…?
Now I have a much larger range throughout the house and garden, and can connect my 360 via cable to the second to get a decent connection
Its reasonably easy using a variety of the web based interface, telnet, and editing the backup config files. I found I had to do the latter to change certain things which can’t be changed… or disabled while they are in use. I’m availableat my nick @ubuntu.com if anyone’s interested.

Oh… and for the love of god turn off the internal DNS server on BTHomeHubs… and any SpeedTouch I’ve come across. I don’t know why but I can’t manage to keep one online more than a couple of days with it on, not that you get many advantages from it.
