RE: 5521 No wireless network available
And my story continues)
I took laptop from work to my home. At home WiFi was ok, without any problems. Today when again at work I see that WiFi adapter is present but laptop do not see any WiFI networks (there are a lot of them in the office). After reboot it finds all networks.
The same problems I had a year ago and it was fixed by removing some Windows updates. Now it appeared again ((((
But Dell do not care about it ((((
