I've recently purchased this TP-Link WN722N wifi adapter to work with my Goflex Home running on Archlinux-Arm5vTe. Since purchase haven't quite got it to work. It authenticates and associates to the AP alright using wpa_supplicant command and netcfg. But when I run a dhcpcd wlan0 it fails to get me a valid IP and pulls a 169.254.x.x on me. I've seen you guys resolve tedious problems than these so I feel mine will not take much of your time.
Here are few pasties for reference, do ask for more if you need any:
Please help me out guys!!
