WIFI weak signal

[rverdlm]

When we pull into a CG with WIFI and get set up many times the signal is so weak it's hard to use. My wife and I both have laptops and use them at the same time. When we have our DirecWay dish set up it runs through a router so we are both on wireless. Is there any way to use an antenae through my router? We don't want to be hooked up with a wire running to an antenae because we don't like wires running across the floor. We also would need 2 antenaes for 2 computers. Any solution that will allow us to increase our signal strength would be appreciated.
