@kbanurse Are you able to join other wireless networks? Coffee shops, etc?

[kbanurse]

No...none

@kbanurse Have you ran the Wifi diagnostics in Samsung Members App -> Support?

If you need to contact Samsung support, here are some options.  

For immediate assistance, one option is to use the Samsung Members app -> Support -> Send text. This will open up live troubleshooting.

Another option is to contact Samsung support via https://www.samsung.com/us/support/contact/

Yes phone passed all diagnostic tests.... still no display of networks

@kbanurse I would recommend contacting Samsung support to get the device evaluated.

Good signal but perpetual spin waiting to find network even if added manually

I went to ibreakufix, utilized samsung support and chat gpt winds up giving me the straight talk, the update burned out your antenna. I even did the factory reset. Don't waste the time/$.

My fold 3 has lost wifi as well after recent update 9/4/25, apparently the update burnt out/ broke the internal antenna.. forced to get a new device because of an update issue caused hardware malfunction. Awesome.

It's samsung way of getting you to update rendering your device disabled but still functional..
