Here's a thread on
RV.NET Technology Forum that will be of interest. I copied the starting post:

I have spent many months trying to find the best allround solution for getting WiFi service into the RV including custom routers, bridges etc and I have just come across the best solution bar none!
It's a Long Range USB adaptor ($50) and a Super Cantenna ($40).
We are at 1000 Trails in Las Vegas and anyone who has stayed here knows just how bad the WiFi service is, only available by sitting outside the store with a laptop.
I'm sitting here about 150 yards away from the store with the cantenna sat on the table inside the RV with a signal strength of -51 dBm. I'm seeing a 400kbps download and 250 kbps upload - totally unheard of.
In addition I have an active USB extender if I need it to move the unit outside to get even better signal strength.
The USB Adaptor is a high power 200mW unit from EnGenius and I bought it from
www.newegg.com - the Super Cantenna came from Frys Electronics.

Adapter
High Output Power up to 200mW (23dBm)
Super Cantenna
# 12 dBi gain
# 30-degree beam width (approximate)
BTW, the adapter is USB, so it can be just stuck out the window with its own antenna for simple setup or used with the cantenna or other antenna like the ones previously mentioned here.
The advantage to using a program like Netstumbler over
Windows Zero Config is that you can set it up to refresh itself every few seconds while aiming your antenna for best signal. When set, close NS and open
Windows.
The thread above mentions
WiFi SiStr which shows updated signal strength but is not controlling the adapter. Haven't tried it yet.
