Best way to improve WiFi reception

[mmreagle]

I have an RV that I park on a friends property. The house where the wifi exists is about 100 ft. from the RV. Unfortunately my desk is on the far side of the RV away from the house and I get sporadic signal strength. I currently have a Trendnet TEW-680MD bridge but it has no ability to connect an antenna. I have looked at different solutions but only managed to confuse myself. I looked at the article "Best wifi routers" here where they suggested the Linksys WRT1900ACS. I also looked at various antennas that I could mount on the roof of the RV but again got confused. I am not looking at spending a whole lot of money but I want a good solution as well. Can someone help clarify what my best solution could be for this situation?
Thanks!

You need a directional antenna on the WiFi router pointed at the RV, you can also get a WiFi card that has an antenna port Or try using a USB extender (6 feet is good) and put the adapter out a window to prevent the RV shell from interfering with the signal.
