Wifi Not Working

[tntitans37216]

Saturday my phone's (fold 4) wifi stopped working. It doesn't recognize my home wifi (been connected for years), any of my wifi car dash camera (work truck, jeep, or personal truck). Sunday I did the reboot with volume up and power and cleared the cache. When it restarted it recognized my home wifi and Insta360 X4 camera. Then monday when I work up it was disconnected from the wifi. It wouldn't recognize any wifi near me, usually 3 other places show up. I just now cleared the cache and it isn't recognizing any wifi. I reset the wifi/bluetooth setting and nothing. Just have to repair every bluetooth device. The last phone update was about 1 week ago and worked fine after the update.

Boot up into Safe Mode and see if that helps. If it does, a 3rd party app is somehow blocking/modifying your connection Settings. If this persists, most likely it's a hardware issue (although you can run the 'secret menu' hardware diagnostics and confirm if that's the case as the WiFi antenna test would fail).

I did the safe mode and still the same. I'll have to look into the diagnostic test

Watching one youtube video about wifi on/off history. Samsung Smart Switch was on and I disabled that. Now it recognize wifi but connects and disconnects a few seconds later. Also disconnects bluetooth randomly.

At some point might have to try factory reset
