When securing your wireless router, you are given basically two choices.  WEP and WPA.  WEP encryption does two things:  it encrypts your wireless internet with a hex (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F instead of 0-9) string like “5FE321A” and it sucks.  It’s a pain to remember the key and it’s easy for hackers to break.  WPA allows you to encrypt your wireless with an easy to remember passphrase like “omgthisismypassphrase” and is tough to break.

So just remember: WEP bad, WPA good.  Use WPA.
