Can't get it to work at all!

Hi-- I got a Surf On the Go to use in my RV. I am plugging everything in as instructed, but when I turn it on I stop having any wifi. I’m not tech savvy, but it seems straightforward. I’m registered. I have a Mifi hotspot plugged into the Pepwave, and the Pepwave is connected via ethernet and adapter to my laptop. Any ideas?
