I have a Linksys BEFCMU10 cablemodem and a WRT54GL router with Tomato 1.27 firmware on Cox cable. My question is this: I get what seems to be random disconnects from the internet, where the cable modem lights are still normal, but I can connect nowhere, either via a url or an ip address. At the same time these disconnects are happening, I can go to the router's Tomato management webpage, and release/renew my external IP address from Cox's DHCP server. I've had Cox look at the signal levels on the cable modem, and they say they look fine. What brings back the modem, for sometimes as long as 17 days, is several power-cycles of the modem. I don't understand the underlying cable modem technology too well, but I do know that if I'm able to release/renew the DHCP-provided WAN address, I'd expect that the cable modem was working ok... Anybody have any ideas??
My immediate nextdoor neighbor has Embarq/Century DSL and it is slooooowww... I have an arrangement with him to allow me to use his wifi when my cable modem is down, and he can use my wifi when his dsl is down... so far, it's been me on his system everytime and he's never had to use mine... Other than the slower speed, I guess DSL is a bit more stable than Cox cable... – LVDave – 2010-03-19T01:06:19.723
