Just purchased a wifi booster/range extender for the MH.  After looking at the offerings from the 2 main providers at the Rallies that we have been to, MotorhomeWifi and WifiOnBoard, decided to risk it and Do It Myself (DIM, hmmm!!).  Nothing wrong with either of the offerings I saw but the prices seemed quite high, a basic system would cost anything from 130 to 160 pounds for just wifi and that included compromises, could be up as high as 350.  Of the 2 options, WifiOnBoard is probably more flexible antennas, 3/4G etc.., but MotorhomeWifi is the easier to use and setup with a much better interface therefore possibly more reliable.
When I looked at what they did and how, basically they had combined the following:
- decent antenna
- wifi router
- wifi network adapter
So, I have just bought from Amazon:
- Alfa R36 802.11 B, G N, Repeater And Range Extender For Awus036H (56.99)
- Alfa AWUS036NHR – High-Gain 2000mw 2W 802.11 B/G/N Wireless USB Network Adaptor (20.00)
- although the AWUS036NHR comes with a 5dBi antenna, I also bought a seperate CSL 12dBi antenna for wifi, comes with a nice long cable and a stand for outside (8.85)
- Total outlay 85 pounds delivered, could have got it for less than 70 but wanted it asap.
How it Works
The AWUS036NHR via the supplied Antenna picks up the external Wifi connection, this plugs into the Alfa R36 via a USB cable, the Alfa R36 is powered either via 230v or 12v connection.  The Alfa R36 provides a wifi and lan cable connection for my devices in the MH.
In theory this should provide similar functionality to the WifiOnBoard and MotorhomeWifi systems and if necessary allow me to use any 3/4G dongle to replace the AWUS036NHR if wifi is not available and mobile data is.
There are YouTube videos to demonstrate the above setup and driver updates available, so it should be a easy enough.  Will be setting up at home and then testing at Malvern and Cannock.
We shall see?
