Unable to connect to Wifi before login screen
Hi can anyone help with this.
My Macbook pro fails to connect to any wifi signal at the login screen.
If i connect an ethernet cable it connects at the login screen, and i can see the ip address when clicking on the clock.
After logging in with a local account or a cached account, it connects ok to the wireless network.
As it fails to connect before login, am i right in assuming that it is not applicable to any user acconts.
MacBook Pro, OS X Mountain Lion (10.8.5)
