I have something similar to that already. I wonder how much better that is over what I have? I was looking at something like this.

I don’t know if anyone is using a similar setup and had any input.
Instead of a Mofi, since they're expensive as heck, look into the GL.iNet X750 with the EP06-A modem. You can only get this from their website, otherwise amazon has a crappier model for the same price (although free prime shipping)

I can help you configure the mofi or x750 if you buy one.
