Ok, so I was able to connect to my wifi by running the 'wifisetup' command from CLI after using Terminal to connect via SSH.

Can somebody explain to me why the web interface is broken?

I'm having a similar issue with my Omega2+, during initial setup it was able to connect, not since then. The built-in AP works so I can still connect to its web interface but I had no success in adding additional WiFi networks - they are added but it won't connect. Also I'm unable to delete the networks via the web Settings page, nothing happens when I click the remove button. Also the re-order buttons are not working at all...

Any suggestions on how to fix this would be much appreciated!
