Z Fold 3 using from Hong Kong, with same issue, after update One Ui 5.0 to 5.1 and the phone restart it could not go on Wi-Fi. Tried "General Management" "Reset" "Reset network settings" did not work, tried "Factory Reset" and did not resolve it.
Brought it in to service center and they told me the Wi-Fi module is damage and need to change it, but because its link to the LCD it will need to be change as well (repair cost 4200hk$ 535US$) after 2 day back and forward they told me they give me 50% off the repair cost, as I did not want to wait anymore I paid for the new quotation and now waiting for my phone to get repaired because I press update 5.0 to 5.1 lol.

I have currently find around 10-15 case that involve Z Fold phone and One UI 5.1 – Wi-Fi problem. Please Reply post if you have this issue. Thanks in Advance.

There are a lot of complaints about the One UI April Security patches messing up the ability to use WIfi & Bluetooth. Personally mine was killed after restart of the F926USQU3FWD1 build update for Z fold 3 series SM-F926U on April 28th. Even their preferred Samsung repair centers cant find the issue or fix it. Samsung has my phone currently under repair (out of warranty of course). Ill update as I get a final repair status.

Same problem. This is clearly linked to this update. Your phone will gradually get worst in the following stages: First the wifi didnt work. Then it would turn the phone off if opened inner screen. Then inner screen wouldn't turn on at all. Then both screens dont turn on, It's just a grey fuzzy screen, completely unusable. 20230701_225605_15460_1688248565.jpg

Same issue here - it won't connect to my home WiFi, the mobile network connection is patchy and slow. Additionally, other things no longer work including being able to unfold the device and have the content transfer onto the folded out screen (I have to close it, open the screen, and THEN open the app I want). Auto rotate is no longer working, and the sound no longer works on most but not all apps. None of the fixes I have tried so far have worked, or have only partially helped.
