For the last 30 days, my S10+ has been unable to connect to any 2.4ghz wifi network. I think one of the last two firmware updates did this, and it is very annoying. My car has wifi and it ONLY has 2.4ghz wifi so now my car's data connection for wifi is useless for my phone. (Yes, I have already tried forgetting networks and rebooting the phone. All useless.) How do I fix this immediately, please???
Try do a wipe cache partition first as you have update firmware before.
- power off your phone - press and hold vol up and power key until you are in recovery mode - use vol up and down to navigate - select Wipe Cache Partition - press power to confirm - Reboot system
