After random disconnection the same WiFi networks(or any other) are not able to connect. Showing "Can't connect to this network" error.
After turning off the WiFi and then on, it does not detect any networks available.
After resetting the network from "Network Settings" / Restart of the system resolves the problem temporarily but again issue persists within few minutes.
No such internet problem with Ethernet connection.
Login with PIN :
Intermittently PIN login becomes unusable. Faced this issue only once so far.
I have tried re-installations, cleared dna cache, resetting the network etc. Nothing resolved the problem permanently. A ethernet cable connection is stable but not wifi.
Could you maybe also share name of your Wifi chip, active driver, and whether you really are on 22000.160 or 22000.168? I just did the upgrade within W10 method and for now I haven't encountered the bug.
