I came across this cool website today.. http://networklessons.com
On here it has “How To” guides for Cisco equipment setups and and walk through guides… so be sure to check it out!
One which I found interesting was authenticating WPA2-Enterprise via a RADIUS server with Windows 2008 using PEAP and EAP-TLS, which explained it step by step quite well.
