Router recommendation

[Burble]

Friday next week I'm having my Virgin Media cable modem upgraded to 50Mbit and in the process am saving the company the princely sum of £1/month. Bargain.

At present I'm using a Linksys WRT54GL running Tomato and until about 3 months ago it had performed flawlessly but lately it seems to get its knickers in a twist and stops routing. I can fix it by logging into the web interface and doing an release & renew of the WAN IP address but it's not ideal because I've got a Slingbox at home and it's a pain when the router throws a hissy fit and I can't watch the Slingbox from whatever crap hotel I'm in. I could schedule a reboot but I'd rather solve the problem than work around it.

I've seen reports that despite having a 100Mbit WAN port the WRT54GL won't give more than about 30Mbit so I'm looking for a new one.

Virgin Media will give me a router as part of the installation but I need nice things like PAT, bandwidth monitoring and so on so whatever thing they supply won't be of much use.

Any suggestions? I like the way Tomato is extremely easy to configure so I'm wanting to keep something GUI based if possible. I could use one of the spare Cisco 1712's or similar that I've got at work but away from work I don't want to faff about if I want to change an ACL or whatever.

I've got a PIX501 sitting idle at home but that baulked at the 10Mbit I originally had from Virgin. Maybe I'll give that another try first of all.
