As of yesterday I have only been able to access the guest wifi account from my wireless router. At first I thought it was a router issue, but 3 other pc's on the network have no issues. I am running ubuntu on 2 of them and windows 7 on the third. This machine is running ubuntu 12.10, and again i can only access the guest wifi account on my router. This only started yesterday. until then it as working fine. any help would be much appreciated. Thanks in advance.
