Anyone know anything about cable modem connectivity issues?

5. When you say it loses its connection...

What are you basing that on: flashing cable light on the modem, or loss of Internet access on the computer?

My computer goes offline once in a while and it's because the cable modem lost contact with the Cox signal briefly and when it regained the signal my computer did not restore the network connection with the modem. Shutting down the modem does not fix that, but rebooting (restarting) the computer does.

You can tell if it's the computer network rather than the cable modem by looking at the lights on the cable modem. One of then indicates the status of the cable signal, steady indicating connection and blinking meaning no signal.

The Charter techs should be able to read the signal all the way to your modem, by the way, just as they can to your television box, and I have to wonder why they are not commenting on that. Last time I upgraded my modem it was because the Cox tech said, "I see you have..." and told me my cable modem was a lower speed than the service they were providing.
