Internet Connects/Disconnects Randomly

[ToyotaSupra]

I'll be playing a game, surfing the web, or something else and my internet will just cut out for about 5-15 minutes randomly. Comcast has came out and checked a few things, they placed some type of amplifier for the signal and that seemed to work. I've updated drivers for my ethernet? card. I have a Linksys router, I've tried updating the drivers for it but when I have I never get a connection. I know of nothing else to do right now.

Your post states that the Amplification device Comcast put worked, so are you now saying that since you've updated the firmware on your router you can not get a connection??? What about the status lights on the modem when you are getting disconnected? Do you have Keep Alive checked in the router?? It does sound like the provider is the problem..

I've tried updating the firmware before this a couple times but I always end up rolling the system back. The modem will go offline, the lights will all be on and the "online" light will just blink on and off.

Whats this Keep Alive thing?

if your online is blinking at anytime, then you still have a signal problem with comcast, and the amplifier they put on is not fixing the issue. if you have a motorola modem, you can log into the modem to check your levels. in your web browser type 192.168.100.1>click the signal tab and it should show your RF levels carrying the signal to your modem

acceptable levels are
signal to noise 30 or higher
downstream -15 to 15
upstream 42 to 54

I'm getting...
35 to 36 Noise
-8 to -9 Downstream
58 Upstream

That's when its working.

your upstream of 58 is causing a weak signal and causing and intermittent connection. call comcast and have them send another tech out. or if you have a tv splitter on the cable line, try removing it, and then go back and check your levels?

idk how comcasts policies are but the cable co. that i work for, if a cu has had 3 techs out in a 3 month period then a supervisor field tech needs to be sent out to look and fix the customers connection.
