WiFi is the popular wireless networking standard. This class covers everything you need to know to setup, secure and access wireless computer networks.

The class begins with a brief comparison of wired vs. wireless networks on things like cost, security, speed, etc. Next, we cover the different types of WiFi networks: A, B, G and N, exploring the pros and cons of each. Then we go over the configuration options and parameters involved with setting up a new WiFi network. A big ongoing annoyance with WiFi networks is poor reception (signal strength), so the class covers a number of ways to improve reception.

Every computer network depends on a router, so the class offers advice on purchasing a router.

Security is critical with wireless networks and the class reviews many steps you can take to secure your home/office wireless network. But this is only half the story, we also cover securing your computer when using a public WiFi network such as those at Starbucks, hotels, airports, etc. If you are not familiar with WiFi security you should not be using a wireless network.

The security topic includes the use of Virtual Private Networks (VPNs). VPN is only the beginning of the alphabet soup involved with wireless networks. We also cover: WEP, WPA, PSK, TKIP, AES, RADIUS, WPA2, WECA, SSID,  DHCP, MAC and NIC. 

To tie everything together, the class ends with a demonstration of configuring a router use with a WiFi wireless network.

This is a three hour class. For links to WiFi articles and web sites see the page for my Networking For Homes and Small Businesses class.
