To anybody: I really don't know much about computers, I have a westell versalink 327W, and a wireless network card (Dell TrueMobile). A neighbor told me he had accessed my wireless network. I know this might sound estupid, but HOW DO YOU SECURE A NETWORK? What do I have to do so others don't use my connection? Thanks in advance..Lisa

In general I always suggest...
1. Change the admin password on the wireless access point (WAP) to something other than the default. Use a strong password.
2. Change the default SSID to something other than the default. Use a unique SSID so you can easily identify your network. Do not disable the SSID broadcast. You only cause other issues. Cloaking your SSID is not a valid security measure.
3. Use the strongest encryption possible that is supported by your hardware. WPA2/WPA is recommended but if your hardware only supports WEP use 128-bit WEP at a minimum. In the case of WPA use a 63-character key. Personally I use WPA-PSK (TKIP) with a 63-character key to encrypt my home wireless network.

4. Do not give the key to your neighbors...
5. If your WAP allows for remote admin over the wireless link disable or turn that off. Only administer the WAP via a wired connection.
6. Use a software firewall on your local PCs. Use the XP SP2 Windows Firewall or a third-party firewall like ZoneAlarm to block unauthorized access to your PCs. Personally I use the XP SP2 Windows Firewall on my PCs and setup File & Print Sharing so only specific PCs on my LAN (I use static IPs for desktops) can access each others files and printers.
The real key to all of this is to use as strong encryption as possible on your wireless segment.

General Steps You Can TakeAlso note that I always run the XP SP2 Windows Firewall on my wireless laptop with
NO EXCEPTIONS enabled. That way if I am at a public wireless hotspot I am not worried about incoming probes. When I am at home and I need to get a file from one of my home desktops to my laptop I initiate the file transfer from my laptop...
