Does anybody know if this will be investigated, or if WPA will be implemented at a later date?
If WEP doesn't work for you, it's most likely that your WEP password is wrong.
Note:
In opie-networksettings you may not just enter an ASCII WEP passwort
(ie "some_password"). If you want to do that, you'll have to prefix it with "s:"
(ie "s:some_password").
Otherwise the system will assume that "some_password" is a HEX key and hence won't work.
WPA works right now using wpa_supplicant. Zecke (Opie dev) was so nice to include it into OE.
However, there is no GUI to configure it, and only experienced linux users may actually be able to use it.
If you want to have a go at it, google for "wpa_supplicant" howtos. It's exactly the same as on a normal
Linux desktop machine.
Another problem with WPA might be your CF WLAN card. I had to upgrade the firmware of my Bufallo for WPA to work.
