If you're running a home network, I would start with the following changes:
SSID - change to some new name-oddball mixture of alpha/numeric on both
router and computer. After change is made and network reestablished, stop
broadcasting the SSID (casual passersby won't know the network is there)
Enable WEP (64 bit slows down the network less than 128 bit). On the router
set up page, input a 10 digit hex code (make one up with any combo of alpha
numeric with the alpha restricted to a-f and numeric 0-9). Put them in
both the router and computer. Network will be lost until they are inserted
on both sides.
That's generally enough for most home situations. You could go further in
restricting access to particular MAC addresses (namely the MAC address of
your laptop).
A dedicated hacker could still access your network, but doing the above will
deter the neighbours and casual passersby.
