There are several reasons why the Wi-Fi does not turn on, I will try to describe some of them:
The first reason, which is quite rare, is incorrectly set date and time. To fix it, you need to go to "Settings", then "Date and time", there set everything correctly.
This problem often occurs when the password has been changed, but the Smartphone "does not know" about it. It is necessary to enter the settings of Wi-Fi connection, delete the profile of the network with which the connection was established and reconnect.
The third reason when Wi-Fi stopped turning on is a software failure. You can try to solve the problem by using a special utility "Wi-Fi Fixer". There is no need to change any settings in the program. Simply download and install it.
If this does not help, you can reset to factory settings: go to "Settings", then "Restore and reset" or visit this website.
I hope this helps you. Good luck

Thank you Gerald
its very kind of you to answer my question and explained it in such details, I appreciate it very much.
however I have tired your recommendations other than factory reset, but no avail.
one thing that i suspected is that the very chip itself that is having some issue
my device is one Plus 5T which runs on snapdragon 835.
and one other things i notice is that my LTE network will not work as well once i turned on wifi or bluetooth of both, which means if either bluetooth or wifi is on along side with LTE network, the phone will indicate no sim card is available. the only way i am getting back my LTE is to turn off both wifi and bluetooth and restart the device then the LTE is back to working condition, with very low LTE network speed with data transfer speed always less than 10 Mbps( i have tried the same sim for other phone which is between 20 to 90+ Mbps).
do you happen to know if the Wifi module stand alone component or it is integrated into the processor itself?
