Here's the deal. I finally got around to locking my wireless router but when I did the signal on my iPad 3g and iPhone 4 dropped from full to 1 little dot. I have not signed up for 3g coverage and cellular data is off. They still worked, but slow. It never asked me for a password. I can't get it to ask for one and don't know how to put one in. I went back into my router and turned security off and both signals came back to full. Did this several times with same result. My laptop works the way it should. Asked for a password, put it in a voila! HELP! Tired of neighbors sucking my bandwidth and God knows what else. Any help will be greatly appreciated!
