Recently my wifi has begun failing, usually with the small triangle warning. This happens randomly as far as I can tell.


A look at event viewer has not been helpful, it will almost always show a DNS timeout error, but since none of the other 10 or so devices on the network are having issues I don't think this is the actual problem. It will also sometimes but not always show a WLAN autoconfig error Reset/Recover.adapter followed by a WLAN extensibility module has stopped C:\WINDOWS\System32\bcmihvsrv64.dll


Turning on and off wifi via the button from toolbar will fix it after about 10 seconds.


I have tried all the basic stuff, uninstall/reinstalling device, update with latest drivers, etc.


Obviously nothing has worked and I need help.


How can I proceed?


Tech Info:

Windows Version 10.0.10586 Build 10586 (x64)

 The clever devils at Microsoft have put in a new so-called power saving feature.  Go to Control Panel -> Power Options -> Change Plan Settings -> Change Advanced Power Settings -> Wireless adapter settings -> Power saving mode.  Change both options there to Maximum Power .  That fixed the problem for me.

 Now wasn't that a clever thing for MS to do?  :flame:

Make regular full system backups or you'll be sorry sooner or later.
