ROG5 mobile phone can't connect to WLAN after updating.

First, check whether the wifi of your mobile phone is automatically turned off by the system after upgrading, or whether it is prohibited by the system itself. If this is the problem, it's simple, just turn it on between times! Check whether the wifi router is turned on, and try wifi more. It is possible that the wifi you used when updating may not be able to connect after you update, so you need to try another wifi. If something else is available, you just need to wait 24 hours to connect. If all else fails, please refer to the following methods! Make a phone call, call mobile phone customer service, find a manual service, and then let them solve it for you. This is the most direct method, but I'm afraid the phone can't get in! Reset the mobile phone, reset the mobile phone in the mobile phone system, and restore the factory settings. General problems can be solved!
