My router loses connection to network several times per day for several minutes at a time.  ISP Comcast says that problem is not with them. n This has been going on for several months, and I bought my modem/router as new this past May.

I can't tell you what to do. 

There's con/pro's to both. 

1. call comcast: if it is a line it could fix it. If the problems internal to the home or the modem, they can potentially charge for tech visits

2. new modem/router. if its the line, the probably won't fix the issue. 

3. rent one. con: costs $ but comcast is reponsible for making sure it works.

do you have a screen snip of the cable connections page and logs? Those help check the signal back to comcast. they're great at saying "its not our lines" as a first response even if it is. 

Do wired and wireless devices drop? 

[dune21]

I only have wireless.  Here are some snips that I took.  Do these help identify the problem?

posted photos need to be approved by a moderator and that can take a while. 

if you click on "choose file" and attach them, they can be viewed but its limited to 1 per post so you have to do each one seperate. 

[dune21]

Thanks.  I sent three photos, so I'll send one now, and one each two more times.

[dune21]

I hope that does it.  This time the attachments didn't seem to get attached.  I have never done this before, so it's all very new to me.

You didn't hit the cable connections page. 

but your logs show t3t4 errors which tend to be line issues. make sure to remove any splitters, amplifiers, or attenautors from your lines. 

[dune21]

OK.  Here is the cable connections page.

[plemans]

it doesn't look bad but its just a snap shot from when you opened the page. 

The logs indicate line issues. If you have any splitters, attenuators, or amplifiers in line, remove them. 

[dune21]

I don't believe there are any attenuators or amplifiers on the line.  There may be a splitter in the attic where the cable comes in from the street.  Otherwise, I am connected right out of the cable socket in the wall of my house. 

[dune21]

Also, is there some way to get more detail about the cable connections.  Is there some history page somewhere?

By the way, thanks for your incredible help.

[plemans]

no. the cable connections page loads when you open the page. And it clears on reboot. 

The logs are what will show long term issues. 

[dune21]

And the logs that I sent you don't show any long term issues, is that right?  Therefore, it is your conclusion that the problem is not with my router/modem, but with the cable connections.  Correct?  Is there anything else I might look at in terms of records?

[plemans]

there's always a chance its the modem. 

But t3/t4 errors tend to be line issues. 

[dune21]

What would you suggest as the next step:  call Comcast and request a technician;  buy a new router/modem; rent Comcast's router/modem?
