[HELP] Wifi Feature Issues

I would greatly appreciate any insights and leads that could help.

I have a Galaxy ZFold 3. A few days ago, it rebooted without warning. Since then, my wifi function stopped working. That is, it doesn't turn on altogether.

I have tried restarting my phone. I have updated to the latest software. The issue still persists.

I have contacted Samsung Support. They advised me to reset my settings. I've done all resets except for a factory reset. The Samsung agent advised that I do a factory reset. I am wondering if there is a solution that wont require a factory reset. 

Any help would be greatly appreciated. Thank you
