Basically my laptop is mediocre and refuses to connect to my schools wifi. My Nexus 4 does connect to my schools wifi.

I tethered a data connection from my N4 to my laptop and it works fine but it sucks a lot of data. Is there a way I can tether WiFi (not mobile data) to my laptop from my N4?

I try and use the built-in tether but it forces itself onto my data plan in order to tether, I want to stay on my wifi.
