Basic Internet Connectivity And Modem Help

[GA1050]

Hello we have been using comcast in our house for a while now but for the past year we have had problems with our internet.  The internet/wireless goes out randomly constantly (10-15 times per day).  We call comcast out and they "fix it" but it will only work for a few days without problems then it goes back to its self.  Most of the time it will go out and you only will have to touch the cords in the back of the modem or move the modem around for the internet to go back up but other times it will go out for hours.  

I have a RCA DHG535-2 Modem, then i also have an apple airport express hooked up to it through the ethernet port. I dont know if the problem is caused by the airport or modem or why its happening. If you know anything that can help it would be great if you post it here.

-Downstream

Power: -9 dBmV

Signal Noise Rate: 37dB

-Upstream

Frequency: 22.600 MHz 

Power: 57dBmV

The upstream power is too high and may be intermittently fluctuating even higher out of spec.The downstream power is weak as well. That will cause random disconnects and spontaneous re-booting of the modem. Are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured ?

If there aren't any uneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then putting them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Thanks for the help!  I was able to fix it all by myself without calling comcast out to help.  The problem was, like you said, was that I had a splitter in my wiring to connect my cable and wireless to one outlet.  What I ended up doing was taking out the splitter and plugging my cable directly into the wall.  Then I moved my modem to a different room with a cable outlet and plugged it in to the wall aswell.  Now my upstream and downstream power levels are looking good and there have been no drops in the internet for the past few days.  If anyone else is having this problem it is a really easy fix!
