How WIFI works ( ) Uses radio waves, 2.4 or 5 GHz Networking standards. (a,b,g,n) Communication between the computer through a wireless adapter and an “access point”, usually a wireless router.

How to use a Hotspot WARNING!!!! Unsecured and pirate hotspots are dangerous! – Every password, sensitive number should be “encrypted”. Need a wireless adapter (most of the time, it is built into the laptop). Activate adapter; computer will detect available networks. Choose one, type in credentials and go!

How to set up a wireless network at home Best to use a wireless router, which includes: – Ports to connect your DSL or cable modem and cabled computers. – Logic to direct traffic between the different items “connected” to it. (Called a “router”) – A Firewall – A wireless access point. The first two things to do are: – Connect to it – Change the admin password!

Rules for good passwords Must have capital letters, small letters, digits and punctuation. At least eight characters in length There should not be a recognizable word in it. Should not be known to ANYBODY!

How to set up a wireless network at home (continued) Choose an SSID (something non-obvious). You may want to turn off SSID broadcasting. In area to set up security for network, choose an encryption security: – WEP (bad) – WEP128 (just as bad) – WPA better – WPA2 (best) Each of these require a password (again!) You may (additionally) add MAC filtering
