My WILSON SLEEK CRADLE is the older 815226 model that only works with 2G-3G... Perhaps you are running into this situation... I use mine in the truck and in the RV OFF-ROAD POPUP trailer...
When setup at the campgrounds I get a good 200-feet or so coverage area around my POPUP trailer for our WIFI enabled devices...
I use mine with my VERIZON 3G MIFI unit sitting the cradle. It works great for me with its passive external outside antenna connection even running down the roadway when we are in travel mode. My setup has the magnetic mount longer antenna (Not the short stuby one???) My MIFI unit provides internet for up to five of our WIFI enabled devices... Wife plays with her tablet going down the roadway... Our carrier is VERIZON...
We are probably talking about two different things here haha...
