Modem up and down

exact same problem. routed just restarts all of a sudden. 

Tech Support, please advice. 

We have the same issue.  Three or four time a day our internet goes dead.  Only last 3 to 4 minutes.  Tech said to much usage on our part, but that is not right because it happens all hours of the day and night.  They checked the modem and did ping test and it works great.  Fast speed, just those time it goes down i get a LOT of complaints!  Suggestions?

One said there was another modem within 6ft that is causing problem, we moved it 10ft away.

4 techs later

Another said it was our router, we bypassed our router and used theirs. They say its still our problem.

Too much BS. Very unprofessional!

Hi rashmum.  I apologize for the issues encountered with resolution of this issue.  The Business Service center has been engaged to assist in resolving this connectivity issue.

Thank You

Hi Unclecass.  I show multiple devices for Internet access.  Does this issue occur on all devices simultaneously?  Let me know please.

Thank You

we are having the same problem of internet service going up and down. Internet stays down more than up. It interfers with our customers, ect. Very frustrating!! We did not have this problem in the beginning. Nothing has changed on our part but the service techs all say all is good on Comcast part. Has to be something we are doing. Ready to cancel all service.

Hello 3207,

Welcome to the forum.

Sorry for the late reply to your post.

The community would like to help, but can you clarify a few items for us?

1. Does this intermittent connectivity issue occur mostly during the: day, night or happens all the time?

2. When you were troubleshooting with our tech support.

     Did you connect your computer directly to the Comcast device (modem) and test the service status?

3. Does your network have a wifi router?

Thank you

The client gave up, the techs gave up. On to other ISP.
