I finally seem to have got mine connecting to wifi now on each reboot (still can't quite believe it!).
Here's my etc/config/wireless:
config wifi-device 'ra0' option type 'ralink' option mode 'sta' option channel 'auto' option ht '20' config wifi-iface option device 'ra0' option network 'wlan' option mode 'ap' option ssid 'Omega-831B' option encryption 'psk2' option key '12whatevr' option ApCliAuthMode 'WPA2PSK' option ApCliEncrypType 'AES' option ApAuthMode 'WPA2PSK' option ApCliSsid 'ap7411' option ApCliPassWord '123yadayada' option ApCliEnable '1'
I don't know what most of these do but they all seem to matter and the ORDER also seems to matter! (for some). Specifically ApAuthMode I tried right after key but it didn't like it!
No "config wifi-config"...reqd info is in the iface.
device mode 'sta' works for me. Could also try ap or adhoc. '9' just didn't do it for me!
Anyway, now that I've posted this it'll probably break so speak to ya soon!
