I am securing my network "by the numbers" 1. I changed the admin password. 2. I changed the system ID 3. I turned off broadcasting the SSID. I have 3 XP Pro Boxes. The first computer is hard wired to the router, the other two are wireless. All went well with these first three steps until I rebooted the wireless computers. Then they could not connect to the network. They can see and log into other wireless networks. My network is the only network name on the preferred list. If I turn the broadcast back on, the wireless computers can find the network and connect. If I turn off the broadcast, they stay connected. If I reboot they cannot connect. My next step is to move onto WEP, but I would like to get this out of the way as well.
