Isn't this just the incomatibility problem between the newer cable modems and older routers that only have a 10MBit WAN port?

I had a Motorola Surfboard 4100 modem and after a recent spate of packet loss an engineer came round last week and replaced it with one of the new ntl:250 modems. My old modem was fine with my router but the new one likes to reboot itself every 2 or 3 hours. I did a quick scan of the posts on cable forum and found the reference to the 10MBit WAN port problem.

So, basically, I've had to order a new router. I believe all new routers these days tend to have 100MBit WAN ports but if yours is a few years old it may not have. You can see if it cures the problem by connecting your modem direct to your PC for a day or two and see how many times it reboots (you can see the reboots in the cable modem log). One person found even this didn't help because he had a 10MBit LAN card in his PC. At least that proves the theory anoyway.

Good luck, let us know how you get on. My new router should be arriving today.
