The laptop is connected to WiFi, but turns off

As of today, the wifi on my laptop is not working. When I connect it, it works for about 30 seconds, then it says “limited” and then turns off. All other devices connect normally. Already tried many of the things described on the site, doesn’t help.

Answer

What Windows system is installed on your laptop? And how does it work with other networks? I understand correctly, you have not connected this laptop to the Wi-Fi network at work before? Well, it would be good to check with the person who is responsible for the Wi-Fi network at work, if there are no any restrictions.
