Hey guys my net just randomly drops. I'm using a wired modem and router. I have an xbox 360 and ps3 hooked up as well as my PC. I've tried three routers, 2 brand new out the box, and hooking the cable directly into the xbox 360 and ps3 and the same issue arises. Every few minutes, the net will just stop working. I typically get "connection timed out" or DNS errors on the PC when it's connected. I went as far as to install Windows 7 today because I wanted it and I also want this resolved. I was using Vista. The lights on the modem never go out though.

I was able to resolve the issue over the weekend and was online all weekend but it started back late Sunday night. What I did that seemed to work was delete Bonjour because I heard it might cause issues with Vista. I never reinstalled though, not back on Vista or Windows 7. Should I get comcast out here to check the modem or the lines? I don't see how that could be the issue.

Here is my ipconfig info below (I deleted the numbers):

Ok so it's just the PC that's doing this. I will be surfing the net just fine and get "connection timed out" I was on the xbox all day again yesterday and no issues there at all. It then lets me back to surfing after a short while if I keep refreshing but then later does it again.

I have done a spybot scan, a cc cleaner scan with advanced options enabled, a virus scan with avg, and now a malwarebytes scan and nothing. When I do a tracert during the downtime I get the same error on the cmd that says "connection timed out." Please help me resolve this I've been working so hard on it for about a week now and it's killing me.

It realy sounds like a cable problem. I have a few sugestions that might help.
First of all I realy dont think it's software since you've tried all that.

Try this first...

Make sure your LAN adapter is set to get IP address and DNS automaticaly
Right click on the network icon in the taskbar and open Network and Sharing Center.
Then Click on Network Connections
Right ckick on the LAN Adapter and click properties
Highlight TCP/IP protocall 4 and click properties
Everything should be on automatic!

Now this,
In that same adapter utility click on "configure" by the adapter name
now click on the "Power Management" Tab.
make sure the the box is UNCHECKED that is labeled:
Allow the computer to turn off this device to save power.
CLICK OK.

NOW.

access your router and make sure the DHCP is enabled so it will automaticaly assign everything on the network an IP address.

I realy still don't think that it's in your computer but I had to make sure that those settings where correct.

If that doesn't correct the problem then it's definity a cable connection!
It has to be one of the following:

1. Bad connection in the CAT5e/RJ-45 cable between the router and the PC.
2. Bad connection in one of the cable ends or in the cable itself between the Service Entrance and the modem
3. Not getting a strong enough signal from the cable company or you have an amplifier on your cable line and its causing alot of noise in the line.(happens alot)

note: just because some things are working and others are not doesn't mean you are getting a strong enough signal through the cable line. I am a cable Tech and a Network Tech and i see this problem all the time.

The best thing for a cable modem is to have a dedicated line with no breaks or splitters that runs all the way outside and connected to the main line from the pole or from underground (whatever you have).
It should be seprate from your TV lines!

Good Luck!
