Connecting Arduino Yun to Cell phone wifi

I am doing a class project and it is working fine with Arduino Yun at my home wifi. Problem arises when I try to use the Yun at university wifi because university wifi uses captive portal for login with username and password.

One of my friends said I can connect the Yun to my cell phone and use my cell phone's wifi/data plan to make the GET posts that Yun is making.

I have searched over the web but I cannot find out how to connect Yun to cell phone and using the cell's wifi/data plan.

Anyone know how to do this?

Hi,
you can simply enable the HotSpot Wifi function on your mobile, and then connect Yun to the network so created.

Plan B:

Setup Yun as Access Point.
