@Andrew-Walker Unfortunately I can't try / reproduce your problem now.
I guess you should modify these sections of the 'wireless' file
config wifi-device 'radio0' (???) and config wifi-iface 'sta'.
If I were you I would read "every" wireless howto on OpenWrt - for example at least this one: Wireless Utilities
Maybe this tutorial also helps you Connecting to School Wifi (MSCHAPv2 Auth Type)
(As you know '/etc/config/wireless' changed after FW version v0.1.10 b160.)
