On Abraxas we went a slightly different route to create a hotspot, with a combination of an Alfa AWUS036H 1000mW USB wireless WiFi adapter ($19.79) and an Alfa R36 router ($49.99) along with a 9db antenna for the 036H. For many years we just used the AWUS036H directly plugged into a laptop with great success, but with the addition of other wireless devices (Kindle Fire HD and mini Ipad) pushed us into creating a hotspot.
The small sizes of the two Alfa units allows them to be packed into an outdoor box and placed outside the cabin.
We sourced the two units from

It is not dissimilar to setting up any router however, so if you're familiar with this operation it should be no problem.
