captain,
Just about any wireless router will do for what you intend. As for setting it up, just about anyone posting a response is going to have a "this works best" plan and is what they use at home. There is nothing wrong with that. I personally have my home wireless router set up to use WEP @ 64bit. This allows me to set an 8 character password, though not as secure as 128bit, it works for me. Since I am also running a DOMAIN in my house, ANY outside intruder that gets past the router then has to deal with getting past my firewall, then get inside my network.
I feel pretty secure. If you have trouble setting one up after purchase, please feel free to e-mail or PM me for further assistance.
