We have several computers that from time to time fail to show wireless ssid's. When I disable and enable the adapter in device manager then the connection is ok.
I tried several driver versions, Dell and intel. At least the last 5 drivers. No changes.

I allready tried that. I've seen laptops do the same thing with this option disabled.
Anyway, I'll uncheck this option for all laptop with problems.
I found something on the forums about HT Mode.
All laptops had HT Mode Value = VHT Mode. I change some to HT Mode Value = HT Mode and others to HT Mode Value = Disabled. I'll see if this changes anything.
It did not yet happen on a pc with HT Mode Value = Disabled.
I switched the laptops that had this problem with HT Mode value = (V)HT mode to Disabled and since then i didn't had any calls...
