HP Printer Wireless Set up Issue

So I am having the exact same issue as unclejoe00.   I am switching internet service from Xfinity with Netgear modem router to the TM 5g gateway.  3 devices worked fine before on the wifi…. HP Officejet Pro 8610; Netgear Wi-Fi extender EX 3700 and TP link Wi-Fi extender Model RE220.  All say the fix is to disable MAC filtering on the router or if Access Control List is used in router to manually add the MAC addresses.  The old router and 5g gateway are both set for WAP2 and the devices confirm that security setting.  I tried to work this out with TM customer service but got no suggestions.  I want to cut the cord with Xfinity but need to get this resolved first.  Thanks for any help or suggestions you might have.
