Cannot connect to WIFI after the latest update

[Astroprojector]

I just updated my Galaxy Z Fold4 to the May update. After the update the phone no-longer connects to my WIFI network. All my other devices are connected to WIFI with no issues. I tried restarting the phone, disabling enabling WIFI.

Can you log into your router ?? and see if the router can see your phone

@Astroprojector

Are you based in the USA and have the unlocked, F936U1, device as the European phones on this section of the forum, have yet to receive the May security update.

A good generic troubleshooting guide is > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 

If I can be of any further help then please don't hesitate. Take care.  😎

I had similar issue on my Z Fold 4 after updating to One UI v. 6.

I could not turn on Wifi and Bluetooth radios. 

Resetting network settings did not help.

The solution to my issue was performing "hard power cycle" by holding down the power and down volume button until the phone shuts off.

Having the same issue

Gonna try factory reset and see if it works, nothing else has worked

The solution above didn't fix the issue. Every time the phone restarted the issue reappeared. I had to send the phone back to Samsung for repair.

Any idea what actually broke?
