Att, google and Cox offer this service in our area (and up to 10gigabit in some spots) A properly configured EERO system is capable of 10Gig...

Customers don't understand that the hardware in their hand (phone, tablet, laptop) is not capable of such speeds. You can tell them this over and over and over, they just don't get it. The way to manage their expectation is to show them that the network in their home is working to spec by running a simple speed test on a device capable of operating at really high wifi speed.

I'm asking if anyone here has experience with a device that can communicate with a WiFi system capable of really high speed... 2.5 gigabit, 5 gigabit etc.
