at last, a post about wifi!! (home wifi being a main part of my job)
like many people said here .. apply mac filtering! thats always a good start, but it is also pretty easy for someone who wanted to to spoof an allowed
mac address.
wpa is minimum you should use for security!!!!!! and dont make your ssid/key to easy. wpa2 is stronger (suposedly) and is not compatible with all wifi
adapters yet.
the easiest methods are to not broadcast your SSID ,on most routers broadcast ssid can be turned off. or to simply turn wireless off on the
router.
and last, and more complicated, change the ip range so it only covers the 5 ip addressess needed, and manualy assign the ip addressess on the
connecting computers.
for example, most routers are set to use blocks of ip addressess.. say 192.168.1.1 - 192.168.1.254, which easily allows connections, all that is
needing changed would be to limit the range to 192.168.1.1 - 192.168.1.5, this would give you enough for your router/gateway address and the 4 pc's,
that way it would be impossible for any one else to connect as their would not be any ip addressess for them to use.
best to have a look through the router firmware, if you dont want to break it have a look for an emulator online and check all the settings and
featured their without worrying about anything,
