Can you use the KR1 together with and exress to pc card adpater and a router?

I just got off the phone with one of our customers who tried this out. He is using the KPC680 with the XCA3 ExpressCard to PCMCIA card adapter and the MB6800 he also has the 5dbi antenna for the router. He is using it as a marine solution. He has it his office on land and is transmitting it to boats that are about 300+ ft off the land. He says it works great and is completely impressed with it. He now wants a higher gain antenna to transmit the signal even further. We are also looking into other routers that may possibly work. We will update as we find out. If anyone is using this with solution with another router let us know.
