I think there might be a misunderstanding in this thread.
My problem is not about login in to the Omega, it is about the possible options to connect it to an existing wifi network. It doesn't allow any login that requires a username/password (like WPA2-EAP with PEAP;MSCHAPv2, which is pretty common). Not on the web interface, and not on the console either (I actually took a bit more time to look at the wifisetup script and it only allows:
- no encryption (sigh)
- wep
- wpa with psk (pre shared key)
- wpa2 with psk
now i didn't spend too much time on it, as I'm quite limited with that resource lately, but to me it seems that the underlying software should support the other variants as well (quick look seemed quite similar to openwrt, but i didn't check versions of the packages or anything), but where not added to the wifisetup script (and apparently not to the webinterface either).
The thing is, that being only allowed to connect to networks with shared keys is quite a harsh limit, as a lot of networks (company network, university networks etc) require a per-user login, thus use something that actually supports this.
