You may now close Device Manager and restart the machine to get your issue fixed.

Using Windows PowerShell

1. Go to Desktop, right click and select New -> Shortcut. In the Create Shortcut window paste this command:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe restart-netadapter -InterfaceDescription '<WIRELESS ADAPTER NAME HERE>' -Confirm:$false

Substitute your system root drive with C: and wireless adapter name which you can get from Device Manager window shown previously in this article. In our case the wireless network adapter was Intel(R) Pro/Wireless 3945ABG Network Connection, so the command becomes:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe restart-netadapter -InterfaceDescription 'Intel(R) Pro/Wireless 3945ABG Network Connection' -Confirm:$false
