I've been trying (and failing) all weekend to get my homeserver connected via Wifi (I know it should be cabled, but a house move is imminent ;-). The setup is as follows:
- HP N40L Microserver
- Ubuntu Server 12.04 LTS 64bit
- Edimax EW-7612UAN V2 - USB Wifi adaptor
- Tenda N150 Wifi Router - run 1 SSID as b/g/n mixed mode, channel 6, WPA2 Personal, AES
On a fresh install of Ubuntu, my output is as follows:

If I try to force a DHCP request with wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext && dhclient wlan0, it just seems to hang and I can see DHCPDISCOVER requests in syslog.
I must be doing something silly to get stuck, when other posts make it look so simple (e.g. How do I connect to a WPA wifi network using the command line?).
Does anyone have any ideas on how to resolve this?
