I have my work PC with a USB Wireless Adapter setup as a wireless hotspot. Everything works fine, but every now and then, the iPad loses internet connection even though the "wifi icon" on the status bar shows its connected. I have to turn off and on the wifi for the internet to work again. Sometimes while I'm connected and browsing YouTube, the iPad seems to lose connection by itself. When this happens, the wireless icon on the PC shows the iPad disconnected. Now I know it has to be the PC, cause I've had an iPhone 4, and it used to do the same thing. Anyone know why?
