Compared to my iphone4 when on wi-fi. I am using an airport as my wireless router. It is down stairs in my study hooked up to my iMac. I just bought an ad today and am upstairs with it mainly. Well my wi-fi signal is lousy. My ipad is SloW!!!! My iphone4 with the wi-fi signal is a good bit faster I am really depending on this wireless router because I want to save on my data plan. Is there a repeater that may be needed with my set up? I am sitting here with my iP4 and the iPad that I am typing from with both devices set up on wi-fi. My iPhone has good wifi signal whereas my iPad is not even picking it up. What gives? It detects it one second then nada.
