Just because you can receive a wifi signal doesn't mean your device will be able to transmit back to the access point. Both the access point and connected devices need the ability to transmit packets as well as receive packets. Often times the access point has more transmit power than handheld devices, and access points may use omnidirectional or dirrectional high gain antenna's to boost it's signal further. So while your Ipad may receive a wifi signal from an access point, it doesn't necessarily mean your IPad or connected device will be capable of transmitting back to the access point. In terms of getting better wifi range, it's often better to use an alternative wireless adapter.
