Anyone know anything about cable modem connectivity issues? [View all]

[petronius]

I have kind of a weird problem in that my cable modem (Charter) loses its connection irregularly, sometimes several times per day, sometimes days in between.

The Charter technicians say the signal is fine to the box outside, but something is causing a loss between the outside box and the modem - IOW, it's my problem, and I have to pay for a wall fish to replace the line in the house.

The odd part though: powering the modem off/on doesn't often fix it, BUT, it invariably reconnect immediately if I power off, briefly disconnect the cable itself from the modem, reconnect the cable, and power on.

Any idea why that would work (it's not something the cable techs suggested)?
