I have a problem, so hopefully having some geek friends (being a sub geek myself ya know) and network administrators will pay off.
Last year when I moved into this townhouse I had to buy a new cable modem (Motorola SB5120) to deal with all of the noise on my badly wired apartment cable lines. It was a painful but effective solution, until now. Through process of elimination I’ve eliminated my wifi card, desktop NIC, and router as problem hardware when I finally got down on my knees today and bypassed everything with a straight CAT5 to my desktop. In 3 minutes I had my answer.
I used a seemingly surfboard specific (but other modems probably have this too) utility that gives me signal information and came up with the following:

Here’s my current setup, one I really don’t want to change if I can help it.
- New wall plate connector
- 3ft high gauge line running to a splitter
- 3ft high gauge line running from splitter to modem
- 20 ft low guage line running from splitter to tv across room
- 6ft CAT5 modem to router
- 6ft CAT5 router to desktop
- Modem powered thru power strip (wont reach APC)
- Desktop/Router powered thru APC
There have been a few heavy storms that have passed through recently which I know can reek havoc on a line system, but these problems began before those occured. I can’t translate those signal readings, but to anyone who can, are those nominal, is there something I can do in my home to help this or am I gonna have to have Cox come back out and tell me again “it’s not them”. Mind you I cancelled my line insurance a month or two ago so that Murphy’s Law could screw me.Help!
**Edit*
I guess I left out what the problem was in all this. For the past week or so my modem keeps dropping the connection. It’s very random, and when I reset everything (unplug modem, unscrew cable from modem, unscrew cable from wall, put it all back together) it all works fine for about 5-15 minutes before it drops it again. It’s usually around that point that I’m tired of resetting everything, so I’ll leave it alone and it will eventually connect again without my resetting everything.
And to answer your question directly Brandon, it drops the connection when it’s connected directly to the NIC, and when it’s connected through the router. Which naturally lead me to the modem…
