New Android 11 phone, "Limited connection" wifi

[DanCalling]

I just bought a TCL Alcatel A3 Tracfone, running Android 11, to replace the A2 I bought last year, running Android 10. I have not yet activated the service (current service does not end until 2/2023) but have been trying to go to the Play Store to add some apps, using my home WIFI router, which works fine with the A2 & every other device I have ever connected to it. For some reason, while the A3 "connects" it says "Limited Connection", and basically won't connect to anything, including Play Store. The A2 goes there & elsewhere, no problem. I've tried rebooting the router, an older N150 Netgear WNR1000v2. Older, but again all other devices connect fine. Driving me NUTS! What could the issue be?

Thanks!
