I have local Wi-Fi network with 2 Macs, 2 PC's, iPhone, iPod and iPad at home on Linksys router. Each one of these devices have static IP address assigned. On iPad, when I launch app that requires Internet connection, it takes about half a minute, maybe more, to start syncing, opening webpage etc. Whet it finally connects everything goes fine. Another apps connect immediately. But after some time (i.e. 5 mins) of inactivity problems comes back and I have to wait another 30 seconds for loading page, sync etc. Any help, please?
