i set up a wireless router at my aunts house. the router ranges to 700 feet. i have a laptop and i only live next door. when im sitting at my aunts, just in the living room, my signal is low. when i go home, i dont even get a signal. do i have to add a network to my computer or am i already on her network?! when i connect, it connects to her router, but how come my signal is low?! and in order to share files between our computers do i have to create a network?! how do i do that?! i have a usb flash drive and when i connect it to her computer, it says connect to the wireless access point. is that the router?! please someone help me!
