Anyone have any solution to this. Problem started last week for me. And it's quite annoying as i frequently remote desktop to my computer.
Sometimes the netcard is able to get IP from DHCP on itself but sometimes i have to do a release/renew on it.
Oh and i have in settings to automatically get IP from DHCP even if the IP is always the same.
