Can you try this generic troubleshooting tip please. 

> 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.

Do you have any routines setup by any chance? Which might be stopping the WiFi to connect?

[jimbo1974]

The wifi won't even turn on it goes a dark blue then turns itself off I've done everything samsung and YouTube walk-through stuff think it's gone to go back to Samsung !

Did you try Wipe Cache and repair apps ?

[jimbo1974]

No option to clear cach reset network settings on both sims done airplane mode don't wantvto do factory reset for it not to work think I've got to takecit to shop or be with outvit for a month

Search youtube on how to 'Wipe Cache' if you are up for it can do 'repair apps' in same menu while there.

It doesn't Wipe your phone.

If you are not comfortable doing it best take it to the shop as could be a hardware issue.

[jimbo1974]

Yeah not a year old yet so might just send it back to samsung

I've had the same issues with my 21fe as @jimbo1974 since the Android 13/ OneUI 5.1 update in (?) January. Tried all the advice given here plus factory reset. Still happening! But not a known issue according to my local Samsung store!
Best result is after resetting connections but still reoccurs after a few hours.
Time to move to the forbidden fruit?
