How to extend WiFi range?

What is the source device of your wifi?

As mentioned above it depends on your source of the wifi.. Eg your wifi router.

If it is an AirPort Extreme, buy an Airport Express and set it up as an Extender in your room.

If it is another brand, can buy another identical router and do the same thing.

Get a wifi extender from somewhere like Amazon. Much cheaper (and often more efficient than Airport Express).
