This is a fresh install of Ubuntu 13.10 on a completely wiped clean hard disk. Dual booted with windows 7 (Boths OSs freshly installed). The install is on Ext 4 partition. And my university uses WPA2 Enterprise I believe - PEAP with MSCHAPv2.
Win 7 connects flawlessly and works fine. Ubuntu works flawlessly with the open Guest netowrk of university but not the secured one. It connects fine, and will work for 10-20 seconds but then INTERNET is lost. No ping to www.google.com. However, the network still remains connected. If I disconnect and reconnect to the wifi netowrk again, the internet will work for another 10-15 seconds before being lost. The wifi adapter I believe is "Intel Centrino Ultimate-N 6300". Here is the
