My home Wi-Fi connection uses MAC filtering. How do I connect my iPhone to this?
First you must find out what the MAC address of your iPhone is. A MAC address is an ID built into the hardware of the device. On the iPhone tap Settings > General > About > Wi-Fi Address. This will display the MAC address. It will look something like 00:03:93:XX:XX:XX. Write this ID down. You should now add this to the Wi-Fi router you are connecting to. How to do this will vary across different types of Wi-Fi routers. You should contact your ISP or Wi-Fi router provider for support with this.
