Well, i bet it's not the first time you hear this: I open up safari, browse the web, got 3 bars of signals and suddenly... Safari can't open up any page and i have to switch the wifi off and then back on. Same with any other app, not a safari issue. Every single device that uses my home wifi is assigned a static ip so there's no ip conflict. I've read somewhere that iPhones/iPod touches only use the first DNS entry on the settings, and that if that server fails they don't move up to the second one. They suggested to use an openDNS server, which i did. Worked fine for a couple of hours but the problem came back. Really, its serious, it happens like every 5 minutes or so, you cant use the internet like that. I also forgot to mention that the router is within 3 feet and every other device connected to it has no problems at all, but the really really strange thing is that when i go to my friend's house and connect to his wifi, i get no problems... My wifi has a WPA2-Personal setting, could this cause the problem? (Back on Tiger and Leopard, i had the same problem on the mac untill i switched to WPA. Could this be?). Sorry for the long post
