How to turn your Nexus 4 into a WiFi hotspot

You can set your LG Nexus 4 to act as a wireless hotspot, so you and your friends can use it to connect to the Internet. 

Tap Apps button.

Tap Settings.

Tap More.

Tap Tetherting & portable hotspot.

Tap Set up Wi-Fi hotspot.

Enter the name for your WiFi network (Network SSID), set the security (I recommend WPA2 PSK) so the people that want to use your Nexus 4 hotspot have to enter the password and enter the Password (at least 8 character).

Enable the Portable Wi-Fi hotspot and your Nexus 4 is ready to share the Internetz.

You should now be able to see the wireless network on a laptop or any other Wi-Fi enabled device. All you have to do is connect to it, enter the password you set and you can surf on.

Beware that using your phone as a WiFi hotspot to use the Internet is using your mobile data, meaning if you don't have an appropriate mobile data plan it can cost you a lot.
