I have a 500mb connection from my broadband provider which is verified by the M5's internal speed test. However, even when I use a mobile device within inches of the master M5, I only ever get around...

Hi. I am considering an M5 system but need a "real life" comment. I have a 500mb fibre connection. What speed could I expect through wifi? My current router, a Netgear X10 loses 200mb! Thanks
