wirless connection security issues

["Cherian Thomas" <cherian.in () gmail com>]

Hi all,

           Recently I bought a linksys wrt54gl router for my home
networking use. I live in an environment where we have frequent wi-fi
brute attacks with air crack and so on. This was very evident the
first time I did a check on my router dhcp client table and found two
unauthorized systems accessing my internet connection (I didn't
implement any  authentication method then).
            I am pretty much a newbie into this wireless arena and
therefore ignorant of the best security practices. Can you suggest me
methods to setup a "secure" wireless environment? Consider me paranoid
:-)
            I will post my proposed network topology which can give
you an insight of my situation.
            : I have two connections coming to an xp system. One a
128kbps and the other a 256 kbps one. I did a connection sharing of
the 256 kbps one and a 3rd internal network card takes it to the
router. The router then shares the net wirelessly to 4 laptops. The
problem with the topology is that my first system (connection sharing
system) is no longer in the LAN (any work around's for this prob).
Also can I get access to any software which can help me with
connection teaming the 128kbps and 256kbps one (I know of a software
midpoint. But that company that makes it has bought it down) to
effectively make it 384kbps (I need it to be in the windows platform)
