mobile broadband equipment connection questions..........

Hello, I have what I thought would be a simple question until on got on netgear.com tonight and see that you all have launched a ton of new 4GLTE and beyond products, ranging from routers, to modems, to hotspots.  Bear in mind here first that I need what works with my provider, AT&T.

I have had much trouble in the past with "wifi boxes" being able to carry the load, as I say, of all my devices.  I think they have just enough too much data pull on the super mobile devices that they start bogging down.  So now I have been told to consult with Netgear for more of a "desktop" mobile broadband router/modem device, with a stronger gain/signal, and just much more of a business type router that will bear most all.  So I don't mind buying an additional device, I'll just keep my Netgear wifi box for when I'm on the go and I'll simply leave the desktop unit at home.  I just do not have the time to switch out devices all the time.  Having said this, if I'm going to take the dive into a more desktop 4GLTE AT&T mobile broadband solution - I want to buy the absolute best, latest technology, that Netgear has available to buy, in today's market.  I would also like to get some recommendations of the most reputable buying places/vendors.

I will also tell you that when I did try to view your desktop models of this nature, it just defaulted to a a broken link page.  So please assist ASAP - I need to get this ordered ASAP, this morning.  Please private message me for a quicker response.  I do appreciate your expertise.
