Default Re: Net connection drops a lot.

You can check the modem yourself, dont waste your time calling TWC unless there is an actual problem, the first two or three people you talk wont know **** about troubleshooting... The CMTS gets the information from the modem itself anyway... Time Warner uses SVP by Auspice to query the modem directly for signal readouts... Here is the standard URL: http://192.168.100.1 - I have the same modem so it should work without any problems...

Acceptable Ranges (where modem connection should remain consistent with minimal T3/T4 timeouts, if any)
Rx Power: -8dBmV to 8dBmV
Tx Power: 35dBmV to 48dBmV
SnR: Anything above 34dB is fine


Another way to check for any modem connectivity problems would be to look at the modems log... Post it here so we can have a look see.

Oh, almost forgot... If you get pages that say "This feature not enabled", no worries... Just do this...

Goto: http://192.168.100.1/_aslvl.asp
Change the Access Level Menu option to "Access Level 2".
Password: W2402

Then go back, those options should be visible after that.

Heres what my log looks like...

Nothing major, there are no missed ranging opportunities, T3/T4 timeouts, lost QPSK packets, etc... Those types of things would cause problems... One or two are no big deal, but dozens, hundreds, thousands of those types of entries would constitute a service provider problem.

If you suspect it may be a signal/modem issue, copy paste the signal readouts and the log so we can take a look. Just blank out the modems MAC address pls
