Rebooting modem daily. Xfinity t3 time out

I have to reboot my modem every day because of the xfinity time out. When I try to call, I get a technician tell me to reboot my modem. Which obviously resolves the short term issue. Long term issue is still not resolved. What are my next steps? How can I get a hold of someone else to resolve this?

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your modem or gateway's model number and signal information, especially downstream power levels and SNR, upstream power levels, and error log.

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, 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 a faulty Comcast rental device, or anything outside your home, you shouldn't be charged.

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

Or copy all of the text of the status page and paste it into the body of your next post here.
