I'm trying to make my nexus 4 sharing its internet connection with other devices.
First I've tried with the portable hotspot: when it is ready I try to connect my nexus 7 2. It connects without problem to the WiFi Net but the WiFi indicators never gets blue and I'm not able to surf. Then I've tried the bluetooth way: paired the devices and (on the tablet) checked the internet access option. This time the bluetooth indicator gets blue but whenever I try to load a page the browser loads forever.
The same happens with a macbook.
I think that for some unknown reason my phone is setting up a WiFi Net but it doesn't share its internet connection.
How can I make my Nexus 4 share its internet connection?
My Nexus 4 is running Android 4.3, as does the Nexus 7 2
