I'm using Ubuntu 12.10 and I can't connect to a specific password-protected wifi network. I have the password and I can connect to it with success in the same laptop with Windows 8.
I can connect to other wifi networks using Ubuntu, so it seems that this specific network is different somehow in a way that Ubuntu fails to connect to it.
When I try to connect it stays in "connecting" state for a long time (2-5 minutes) until it fails with "Connection failed: activation of network connection failed" error.
How can I fix this?
