you need to implement MAC address filtering. Check your router's configuration page and look for filtering. Some routers you have to choose Allow or Deny. you want Allow. Then you enter the MAC addresses of the wireless adapters that are allowed on the network. You get this by typing IPCONFIG /ALL at a command prompt on each computer. Scroll down until you find your wifi adapter and look for ''physical address''. It will be 6 pairs of hexidecimal characters

Simple enough. You need to use a system called MAC address filtering. This basically takes a unique identification number from each computer's network card and can be used to set up access/deny rules.

Whether or not you can set this up using a typical Linksys router, I don't know, but I hope that you'll be able to do a bit of searching for the answer now you know what to look for.

In the security section there is the ability to limit connections by MAC address, this address is hard coded onto your network cards. when you do IPCONFIG, you are given the mac address of your network card. If you know the mac address of all the systems you want to use your router you can put these into you router and this will only allow you and anyone you want to use it.
