Several days ago, my kids came to me and said that all wifi, on both the 2.4 & 5 GHz are non-operable. This extended to my wireless HP printer as well. I logged onto the router and found that whatever patching was performed, pulled by hardcoded MAC Address filtering. This adds a security exposure.
I don't know how to open an incident, because the website keeps redirecting me to wasteful docs that do not address this issue!
Side rant:
Another security exposure, in Net Security 101, is to NEVER have your router userid set to 'admin'... never. It boggles my mind that Verizon would set the userid of the routers to 'admin' instead of allowing user-defined IDs. Granted, there's a push to force everyone's WPA-2 keys to be stored at their site and other config information, for whatever NSA requirement, but to change the userid to 'admin', I mean come on.
