Changing of wlan to wi-fi

WLAN is an abbreviation for "Wireless Local Area Network", or "Wireless Network" for short. It is the same as simply saying "Wi-Fi" or "Wireless Network"

So, you are asking us how to change your wireless network to a wireless network, which you already have.

Maybe if you could tell us more about what you are trying to accomplish, we could help.

There is nothing more that we can do.

The use of wlan and WiFi is a regional thing.
