Be clear about what you want to achieve.
If you want your table to connect to WiFi, then this has nothing to do with giffgaff. You need to:
- Turn on your tablet's WiFi
- Select the WiFi network from the tablet, and enter the password if necessary
If you want to use your tablet's WiFi hotspot feature, this is when you share the tablet's mobile data connection with other devices.
- First configure tablet so it connects to mobile data, follow this guide: http://giff.ly/gg_settings
- Go to the tablet's settings, and find the "WiFi hotspot" function. Turn it on, and set it up with a password.
- You do NOT need to download another app for this.
