New modem won’t connect
I have to upgrade my modem by July 10. Everything connects and works fine with my old one. No problems.
However when I try to activate the new one it powers on fine, I scan the QR code and it recognizes that. Then it recognizes my xfinity account and password. But when it goes to the final step to connect it keeps saying try again. it’s very frustrating

It’s connected by a regular cable coming from in the wall?

What modem are you trying to connect? Is it an approved modem? Customer owned or are you renting from Comcast/Xfinity?

Other possible workarounds;
Connect it to the coax line and power it up. Let it fully sync up with the system, and check that the front / top panel indicator light(s) is / are steadily lit.
Then connect a computer to it and open up a browser. You *may* see their *Walled Garden* modem self registration page. If so, follow the screen prompts. Have your mobile telephone number, your Xfinity username and password, or the account number and telephone number associated with your Comcast account handy.
If not, try calling 1-855-652-3446. That is their self-install device activation line.
If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
There is also the option of using their Xfinity App for activating modems;

Good luck !
