My internet is off out of sudden and when i tried to troubleshoot, i found that the serial number in the APP is not match with my physical device. Is that the reason i lost my connection?
Also, the sending light is keep flashing.
I am using my own modem.

The serial number you see in the XfinityMyAccount app is actually the MAC address of you modem not the mfr serial number.
