Hi ,
In this case, based on what you see in the manual, perhaps the Verizon modem must have the Alternate system activated and therefore it must be using a security system for WPA2. In this case, you would have to activate the WPA2/WPA3 mode in the settings and keep the 6Ghz band in mind.
So check your modem configuration initially and see if it has 6 Ghz mode active and WPA2 and 3 security modes.
Hope this helps.
