[GRLUG] Linksys router security setup

[Mike Nicholas]

Next is putting in a WEP key.  Again, the drawback is that devices won't 
auto-config and you have to manually set up any device you want talking 
to your wireless network.  A WEP key encrypts the communication data.
[MN] Typically a choice of 64-bit or 128-bit - keys can be generated with
passphrases if desired.

In my case, I turned off SSID broadcast and then built up a small 
process that asks the router to list all the devices that have made DHCP 
requests lately.  The process then checks that list against known MAC 
addresses and if it finds one without a match, it tells me.  I can then 
go into the router and tell the router to stop talking to that MAC 
(effectively blocking that computer from my network).
[MN] aka MAC filtering - good for small networks; a pain for large ones.
