https://bbs.archlinux.org – I am running Arch Linux on a Thinkpad T420 laptop. When trying to connect to a university network, I am encountering an issue where I am able to connect to certain access points but not to others. I believe the pattern is that I can connect to 5.7ghz access points but not to 2.4ghz access points. When connecting to a 2.4ghz access point, I get a "direct probe to <BSSID> timed out" error. I am using wicd with wpa_supplicant and PEAP/GTC authentication.  This is especially troublesome because I cannot choose which access point to connect to - it is a WPA2 Enterprise network, (HowTos)
