Hi, I had trouble with my gateway and now my mac comes up telling me I must join a network each time. I have to click on it I do not have to put the code in. I use no password. This happens each time I boot the computer. Can someone tell me how to stop this, before the problem it would just connec5t. I have two other computers that are windows and they connect with no problem. I connect all of the wireless. Thanks Don Jones
