The fact that your old modem works still shows the problem. They would have had to delete this MAC to put in the new MAC. So unless you had them change it back in their system, your old modem would not be working.
Try http://192.168.100.1 to see if you can get into your old modem. Post your signal strengths and signal qualities here (basically all information that is measured in db, dbm, or dbmv).
Same issue here in Seattle but worse. I have woken up a couple of times and lost all my SSID’s on the device. All replaced with a version of Broadcom 2.4g or Broadcom 5g SSIDS. Called netgear they claimed they didn’t do it, called xfinity and they claimed they didn’t do it either. However this has happened twice. About once every two weeks the router goes down and I get the cannot connect to cable message and to check my rf settings. This is getting really old. This unit was supposed to work with xfinity and all I have is issues.
