Cable Modem Issue - Periodic Disconnects

[Spartan Erik]

The apartment I'm at uses Road Runner business cable internet; it wasn't until several weeks ago that we began to experience periodic disconnects (roughly once every 5-10 minutes; if we're lucky, once every 10-15 minutes). In fact as I'm typing this my internet has just disconnected!

Anyway, it's an ancient looking AMBIT DOCSIS 2.0 Cable Modem running on NAT mode; I check the modem logs and I see this message: "No Ranging Response received - T3 time-out".

Three users (including me) are running on wireless; two other users have a direct ethernet connection, one of which has his connection split via a Linksys hub. I read how hubs slowed down speed, but even after disconnecting the hub from the network the cable modem will still disconnect periodically.

Any idea whether it's the modem or the cable lines themselves?

Easiest way to tell would be to 'borrow' a cable modem from someone and plug it in.

Hmm, I've Sometimes had the same unresolved issue but i think its the lines when connected to the modem.

Y'see, when the modem connects to the net it uses the lines, when there is a break in the line, there would be a timeout, or so im guessing.

I only had this problem for 1 few weeks, thenI ditched cable for the "privacy" of DSL.

Me and my friend had the same problem with Road Runner. If you are using you're own modem, rent one, if you are renting one, call them and tell them their seems to be a problem with it. Can't wait till true fiber optic is in my area, heh. It seems like TWC tends to screw up modems some how as i had heard other people had the same problems. A network administrator that use to work at TWC said that their is a "hard to install" device on you're telephone pole that may be needed and ain't always installed with some lines so you should contact TWC either way. Hope that helps
