[seriously OT] securing wireless networks

["Ted M. Goodridge, Jr." <tedgoodridgejr_(_at_)_acm_(_dot_)_org>]

I understand this is off-topic, but I thought with the plethora of security 
people on this list, I could get some direction and reliable information.

If necessary, please reply off list, because I know people need on list 
material to be ontopic.

I am moving into an apartment August 1, and I want to have some wireless 
networking for my laptop I will be buying.  It will be a combination 
wireless/wired network with an OpenBSD machine serving as the main 
gatekeeper at my broadband connection.

What I could really use is a starting place, for reliable information on 
securing that network.  I am more than willing to read manuals, 
documentation, but I need a place to start.  (Googling is fine, but I have 
no way of verifying the accuracy of what comes up.)  What information do 
the people on this list find reliable, and secure enough so I don't get 
people accessing behind my firewall using some wireless technology?  A few 
links to get me started is all I ask.

Thank you in advance,
Ted
