Sure, any Thompson branded router
You can't use the BT Homehub on any other SP anyway, they have removed the username and password entry from the firmware.
Maybe I should be more clear on the extra speed issue. My line is very marginal, not in length but line quality. This has been proved by my second line running at 6Mbps where the first ranges between 4.5 to 5.5 Mbps. The Thompson is able to pull the most of the line with the 2wire it was 3.5 to 4.5Mbps. I think I have a split pair as all other testing hasn't thrown up a line fault as such, but for the moment it is proving useful to have a slightly faulty line to play with. As yet I can't find a router that gives me a more stable line as the Speedtouch 546 or better wireless range than the 2wire so I sue that combo for best all round results.
Just in case you were wondering what the worst router I have seen, it's a Cisco, no idea why they are so bad.
Cheers
Cris.
