OK, here's the deal. We have a home wireless network with a D-Link wireless router. All has worked well for a long time. I recently purchased a wireless security camera for a room in our house. In order for it to work I had to switch from WEP to WPA2. I did. Everything seemed fine. EXCEPT...for my apple products. My iphone my wife's iphone my son's iPod my MacBook by son's MacBook Air all intermittently lose wifi connectivity. And not all at the same time. When my MacBook loses connectivity I go to network setting, click on the assist me button and then diagnostic tool after which everything is reconnected...for a while. Then 10 min later, sometimes shorter sometimes longer, it all happens again? It's not that we are losing wifi connection to the router, but the ISP shows yellow or red when I bring up the diagnostic tool. I've tried to reset network settings, I've tried to create a new location...nothing works. Same problems over and over. Help
