I'm still kind of new to the whole wireless thing. I set up a wireless router in our house so we could use my son's old dell laptop anywhere in the house. I set it up with WPA security, and have a pretty strong signal all over. I spent this evening installing a wireless desktop card into our minister's computer to take advantage of the wireless router that is used in the administration offices. I set that router up for WPA, but the signal screeched into low, even though the minister's computer is barely 15 feet from the router. Without the security activiated, the signal is very strong. What's going on? It's making me nervous about installing wireless cards in my personal desktops so I can move one downstairs to use as a media center.
