Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

The ISP (Comcast) technician did say it was a signal problem when he went on Friday January 28,2022 and was told by the tech that he fixed that problem.I forgot to mention I have a AC750 WiFi Range Extender (EX3700) It is near the backyard door not near the cable modem/router could this be an issue?I have this bcause my house is about 1,300Sq.FT it is a one story home, I am not currently home so I can't post the modems connection status page but I will do that once I get home I did call my mom and she says that the Internet is currently working. I checked that there are no coax cable line splitters in the between the modem and ISP service box, Iam using good quality RG6 coax cable up to the modem because that was installed by Comcast I've had Comcast sine November so the coax cable is fairly new. In the event log I uploaded there was a T4 timeout at the top what exactly does that mean?
Something to turn OFF is the extender while you troubleshoot the modem to be sure it's working well.
I will try disconnecting the extender from the wall and see if that resolves my issue. I read in the product description of the nighthawk c7000v2 that this product has High-powered amplifiers so I think the exentender could be messing up my signal instead of helping it. When I get home I will try disconnecting the extender and see if I stop having the no internet connection issue. I will let you know if that works.
