Thank you for your reply, however I am still facing some difficulties.

1. Enable the Access Point (AP) on the Omega
   Does this mean I just need to turn on my Omega? Do I need any other settings for this?
2. Connect the Omega to the Wifi router
   May I ask how do I do this? At this point I am just setting up the initial connection between my Omega and the network. Is it the section where I select from the list of detected networks, select 'None' for security and click configure? (there's no password of the network)
   If yes, then I have tried that and it failed with the message 'Unable to connect to <name of network>'

Is there anyway I can connect to a wifi network that has no wifi-password, but requires a user account? e.g. Cafe, McD's wifi hotspot etc you need to sign up and login with email to use the network.
Currently I am in a university accommodation and it is using such method to authenticate, so is there anyway I can setup my onion with such settings?

I have tried using the GUI and CLI, but to no avail.

Thanks in advance!
