It seems that I can connect to the network just fine, but upon trying to surf the internet, I get about 20-30 seconds of service and then all of a sudden, I can no longer reach the internet. I have been dealing with this for a few weeks now and have contacted the gentoo community to try and get some assistance from them, but it doesn't seem that they can help me right now. I have tried this on my laptop which is also running an ath9k NIC under fedora and I am having the same issue. I've also contacted my I.T. department which expressed to me that they have been having issues with Atheros cards as well. So, for the sake of classes, I switched my laptop over to windows until I can find a way to get this resolved, and I am getting great service running windows 8; before doing that I have tried fresh installs and wiping all of my settings to make sure that it is not on my end. On my desktop I am using a TP-Link TL-WDN4800 and I am able to connect to WPA2-PSK and other non-enterprise networks just fine. I've done a "iwlist wlan0 scan" and the following is the output I received regarding the network: Cell 04 - Address: 00:24:6C:5E:C4:03 Channel:1 Frequency:2.412 GHz (Channel 1) Quality=53/70 Signal level=-57 dBm Encryption key:on ESSID:"Liberty-Secure" Bit Rates:2 Mb/s; 5.5 Mb/s; 6 Mb/s; 9 Mb/s; 11 Mb/s 12 Mb/s; 18 Mb/s; 24 Mb/s Bit Rates:36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=00000030023b991c Extra: Last beacon: 20ms ago IE: Unknown: 000E4C6962657274792D536563757265 IE: Unknown: 0108840B0C1216182430 IE: Unknown: 030101 IE: Unknown: 2A0100 IE: Unknown: 320348606C IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : 802.1x IE: Unknown: 2D1A4C101BFFFF000000000000000000000000000000000000000000 IE: Unknown: 3D1601001B00000000000000000000000000000000000000 IE: Unknown: DD180050F2020101800003A4000027A4000042435E0062322F00 Cell 07 - Address: 00:1A:1E:26:29:72 Channel:48 Frequency:5.24 GHz (Channel 48) Quality=61/70 Signal level=-49 dBm Encryption key:on ESSID:"Liberty-Secure" Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=00000015e96f0925 Extra: Last beacon: 20ms ago IE: Unknown: 000E4C6962657274792D536563757265 IE: Unknown: 01088C129824B048606C IE: Unknown: 030130 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : 802.1x IE: Unknown: 2D1A4E001BFFFF000000000000000000000000000000000000000000 IE: Unknown: 3D1630071B00000000000000000000000000000000000000 IE: Unknown: DD180050F2020101800003A4000027A4000042435E0062322F00 The network is setup with WPA2-PEAP MSCHAPV2 and all I need to log in is a simple username and password.

But none of these or combination of these seems to help with the connection. Would anyone have an idea of why I am having this connectivity issue and how it could be fixed?
