Re: [INTERNET] How do I know if my modem is failing?

said by robman50:

So I wonder since all hardware does not last forever and we rent the hardware from Cogeco if the modem is showing it's age.

Have you tried directly connected to the computer, bypassing your router?

I can't do that. My modem is in the basement closest to the cable line and my computer is up stairs. I don't have any spare coax lines to bring the modem up stairs.

Also if the modem is acting up could it cause intermittent phone problems as well as internet problems?

Also I don't have a laptop that is good enough to run that game so I can not recreate the problem.

Oh another thing, my grandmother keeps complaining that while we are having a conversation on the phone that I keep dropping out. I would think that could be due to a number of reasons. Wireless phone having trouble keeping the connection to the base, poor ground line on her end, or a service issue on either end.

Also what do all those DOCSIS errors/warnings up in that log above mean?

In my router logs I do get the odd [DoS Attack: RST Scan] from time to time, could that do anything?

The modem has a good ping time.

A T3 ranging error occurs when the CMTS isn't responding to maintenance (ranging) requests. What it isn't telling you is it probably retried minutes later and was successful.

A T4 ranging error occurs when the CMTS says it's about to send a new set of maintenance parameters and they never get received.

The DHCP errors indicate there is extraneous information in the DHCP parameters sent to the modem, which is usually harmless.

TLV-11 - unrecognized OID indicates that there is a SNMP parameter (OID) being requested that is unsupported by the modem.
