Hi, all. I recently set up an AirPort network to share a cable modem. It was working great until now. When I'm done on the web I turn my computer's AirPort card off and put it to sleep. Then, when I return and wake it up, the AirPort shows a strong signal and my network settings show that I'm connected to the network, but Safari will not load anything and says it cannot find the server. Mail will not get my email, either. So, I mess around with AirPort setup assistant and AirPort Admin. utility. After a little while, without changing anything, suddenly everything works as it is supposed to. What is going on? Is my AirPort a lemon? Does it not take well to having the computer put to sleep? Any help you can offer will be appreciated because I don't have a clue what is causing this.
