Before getting the Verizon MiFi 4510L, I used a USB Wi-Fire antenna to pull in the campground's WiFi. Can't say it did a whole heck of a lot. If there was a lot of traffic on the WiFi, I didn't see any improvement. But then, this CG has repeater antennas strategically placed. Now, with the MiFi working like it should, I have my own hotspot and it's working fine.
