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
