Many years ago I installed a Linksys router and Linksys wireless network adapter on windows 98 at the time. (I am now running Windows XP.) I set up a wireless network but did not encrypt it. Stopped using it for quite awhile and recently aquired a Laptop running XP and decided to use the wireless again. This time I set up a network and encrypted it. Everytime I search for a wireless network the old one is still there. I am worried someone could be using it. I tried encryting with WEP both at the router and from the client computer. Linksys has been no help. Even when it appears I have successfully encrypted the old network, it still shows up as an unencrypted network. I upgraded the firmware on my router but nothing seems to help. What am I missing?
