Modem error log and current up/downstream issues.
Issue started about 4:00 PM MT. Cable modem reset and now am unable to get a signal.
Troubleshoot steps I have tried:
1) Removed splitter from main cable line.
2) Reset modem (multiple times)
3) Tried the cable line going into my house same issue.
At this point, I have to imagine this is on Comcast's side. Who can I talk to in order to get this issue resolved?
Your modem has lost its connection to Comcast's network. Network connection problems are often due to poor coax connections, usually in or near your home.
If you want to troubleshoot this yourself, please see Connection Troubleshooting Tips. If you can't find the problem or you'd rather have Comcast take care of it, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. If they can't fix the problem remotely (unlikely), insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to anything outside your home, you shouldn't be charged.
Bruce - Thank you for the reply however your canned response does not help in this situation.
I checked my modem from the junction box on the side of my house and did not receive internet. After about an hour and a half, my internet came back.
At this time, my internet issue is due to out of spec power levels provided by comcast. As you can see if my original images the power supplied to my upstream channels is not within manufacturer settings. For the SB6138 modem, upstream power leverls need to be between 45 and 51 dBmV and I am well below at at 26.
Comcast will need to increase my power level so I am receiving the correct service. A call will be placed to Xfinity.
Sorry to disappoint. You stated:
Two things about that:
As it should be whenever your are having problems that you are able to correct yourself.
