1) Enabled Firewall on the router 1) Make sure you DO NOT USE THE DEFAULT SSID and/or Security Key! Change them! 2) Do not Broadcast SSID (Authorised PC will have to know this SSID as it will not be seen in the list of available Wifi) 3) Use 'strong' Wifi Encryption key (WEP - 128 bits)
If you do all of the above, you will be pretty secure! Please note that this is not a trivial exercise as you will also need to amend Network settings on the authorised PCs/Laptops. Hope it helps.
