@chris-lepp if you already repaired your phone I can advise you just a couple of things, maybe few more:

1) Restart your phone in safe mode - will it work better?

2) Try connecting to your wifi with bluetooth off.. will it work better?

3) Try removing SIM card and SD card, connect to WiFi.. will it work better?

4) If your modem/router is dual band, can you try selectively to disable first the 2.4ghz band and trying to connect to the 5ghz only band and viceversa, will it work?
