I recently upgraded my ISP from Ch***** to Lumos Fibre.  Using Speedtest I now have  consistent download speeds of 2.275Gb and upload speeds varying from 1.2Gb to 1.9Gb. I have 4 devices on each of the 5GHz channels (8 total) plus 2 2.4GHz devices.  

   While checking download speeds I compared the Ch**** and Lumos speeds.

                                                     Ch********                Lumos

PC                                               668Mb/22Mb           2.275Gb/1.2Gb to 1.9Gb

iPhone                                                                         769Mb/507Mb

Laptop                                         647Mb/22Mb           556Mb/417Mb

I dam puzzled why the laptop and iPhone aren't faster.
