[TriLUG] Wireless security connundrum

[Andrew Hunt]

Hi all.

I've got a wee problem I'm hoping ya'll can shed some light on, or at  
least point me in the right direction.

I've got two wireless access points:

1) An ancient Aironet 4800E base station
2) A new Linksys one

I would like to tighten up security and allow only designated MAC  
addresses access to the wireless, but I can't see how to do that on  
the older Aironet.

It's a piece of cake on the new Linksys, but the Linksys has an  
effective range of about six feet (no joke), and the older (and wide  
open) Aironet comfortably blankets almost my entire 3 story house.

I'd rather not stick yet another piece of hardware in the mix (I'm  
trying desperately to empty my full-size rack).

Any clever suggestions?
