WIFI turns off on its own......
I had this issue before and got fixed after I restarted the phone.
I have faced this issue with my OnePlus one on CM and even on Oxygen OS. now my OnePlus 3T also behaves same.
hope OP finds a resolution for it.
I have the WiFi connectivity issue. I use2.4 and 5 GHz router and the issue is getting worse now. Really need the developers to fix this.
if you cannot connect to the 5GHz, make sure that you have the last update 9.0.3 OS.
I have the latest 9.0.3 update and still it behaves cranky.
OK, try to remove (delete) the network, and add it manually.
This also worked to some users.
Restarted, power off, delete network, literally slapped the phone on my hands! Guess the result? Came back after 30 mins and then the WiFi signal came back.
I gave you the main two issues but it seems that I can't help you with this.
However, there are still some tips to solve this problem (They may help, the may not). Look for them.
