Re: Does anyone get gig speed???

I got the Xb6 gateway also and I get around 940 MBs wired in and roughly 600 Mbs on WiFi. Is your computer your using a Dell by any chance? A poster on here had a Dell with slow speeds and it turned out Dell loads a program that chokes speeds, he removed it and now get full speeds, just a thought

FWIW @Tuckerthedog, your signal stats are all well within spec.

I"ve used my own modems and both flavors of the XB6 gateway and I've never failed to hit 940 Mbps down (real world maximum speed) over Ethernet. 

 

Since numerous factors might interfere with speedtests, you might want to try using the OOKLA Speedtest app for Windows or for MacOS to eliminate your browser as the culprit.
