WiFi won't connect after update

[H_morgo]

So I downloaded the new update on my Samsung A12 overnight last night and now I can't connect to my home WiFi. It isn't a problem with the WiFi itself because all other members of my household are on it and it is working fine for them. I haven't had chance to see if I can connect to WiFi networks outside of my home but it's becoming quite the problem.

Try forgetting the network in your phone and then reset up the connection @H_morgo 

If your router allows it try splittings it's frequencies to 2.4ghz and 5ghz and name them and then try connecting to one then the other.

Sometimes changing the wireless channel can occasionally help.

Other than that a generic troubleshooting tip 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.  😎
