I have a similar issue to others posted. I'd like to use my Brother MFC7840V wireless all-in-one with my Verizon Mifi2200. When I called Brother, I spoke with 2 different individuals who said that this wan't possible, but their explanation was somewhat beyond my comprehension. In reading the other posts, it appears that a Pepwave Surf Mini might help out, and so I put one on order. I would be very grateful for any help you can offer. It's not even important that the Brother works perfectly; the main criteria right now is to find a solution which doesn't necessitate keeping my high-buck business internet service. Thanks so much. --Judith
