Modem Dropping Out...Please Analyze Log

RBK2 · Post by **RBK2** » Tue Sep 19, 2006 6:34 pm

Howdy,
New member here. My modem [Motorola SB4101]started dropping out a few weeks ago.
Charter swears it is my router. I replaced my Linksys BEFSR41, configured and the same problem happens. Will drop out within an hour or so.
So, I am sort of convinced the modem [3 years old] may be the problem.
Admittedly, I have not tried the modem straight by itself but, why is it I have surfed without any problems for 3 years and now have problems?
Anyway, here is some log data if someone can please evaluate it, and many thanks!

One of the most common things to check, is if you have any splitters before the modem. Especially if outside.

RBK2 · Post by **RBK2** » Tue Sep 19, 2006 8:24 pm

Both splitters are in good visual shape. All cables and plugs are in good visual shape. I have been surfing hard for about two hours this evening and I know what is going to happen about any minute now....

Post by **YeOldeStonecat** » Tue Sep 19, 2006 9:19 pm

Visual won't do it on a splitter...can pick them up at local electronics store for under 20 bucks. That's the first thing I'd try...had to do it with mine in under 1 year..my outdoor one.

The log entries needed to diagnose are lost due to the modem logging debug entries. I don't see a problem with your signal levels so I would probably try a new modem if all your connectors and splitters pass inspection as suggested.

Well folks, it was indeed the modem. Only Charter techs did not want to admit it during three sessions on the phone. The tech who came to the house told my wife that three years got his also. Now, all is well.

Just imagine....a civil engineer who does not know squat about internet systems told 'the experts' what their problem was and, was correct in the diagnosis.
Perhaps I sould go to work for NASA

Thanks for your replies!
