I have cricket wireless broadband, unfortunately I get little or no signal where I live. I would like to hook an antennae to it but don't know where. There is a port on one side but I don't know what it's for and I'm unfamiliar with its adapter configuration . Can anyone tell me both what its for and the adapter type (I REALLY NEED A BETTER SIGNAL) right now I cant even watch a video cause the signal is so poor.
