This post has been replaced by a series of five blogcasts as quite a bit has changed since I wrote this post over three years ago - specifically Windows Vista has a different user interface. The replacement blogcasts are as follows:
How to secure a wireless network: Part 1 of 5 - Enabling WPA on a wireless router
How to secure a wireless network: Part 2 of 5 - How to change the SSID
How to secure a wireless network: Part 3 of 5 - Reconfiguring a Vista client to connect to your WPA secured access point
How to secure a wireless network: Part 4 of 5 Connect using WPA for the first time on Windows Vista
How to secure a wireless network: Part 5 of 5 - Connecting using WPA for the first time on XP
There's an additional blogcast that you may find interesting too titled How to secure a wireless network: How to view the advanced wireless interface on Windows Vista
Note: the original post was worded as follows:
"I've recorded a Blogcast(short focused webcast) which demonstrates how to secure a home wireless network using Wireless Protected Access(WPA). The Blogcast itself can be accessed via this link. I show how to configure a LinkSys wireless access point to mandate WPA for all client connections and I show how to configure a Windows XP SP2 client to use WPA."
I was just setting up a wireless link so this was very useful, thanks!
Some interesting finds for past week and a half
Thank you to everyone I met at Royal Holloway from the MSc in Computer Security (distance learning) course....
