C7800 on Comcast as modem/router w/gigabit internet will not d/l more than 150mbs wired/wireless

Did CC walk you thru a reset and speed test with the model while you were on the phone with them? 

Be sure your using a fast and capabable PC that can handle 900Mb speed testing. I found that some older dual core CPUs can't handle speed testing at 900Mb or greater. My Quad core Mac Mini does fine. So Quad core CPUs are desired for good speed testing at thes higher speeds. 

Be sure your PC doesn't have any background running apps while speed testing. 

Use OOklas speed testing app vs a web browser pointed to there site. Too many ads on the web site can slow down speed results. The installable app is preferred.

As the title says.

New to the community, hello!

My c7800 will not pull anything more than 150mbs on a wired cat6 or wireless.

I'm paying for gigabit speeds and comcast says the problem is with my router.

I've done what troubleshooting I know, somewhat of a novice, reset, factory reset, reboot, get comcast to authorize the router, line test on the cable.

Any help would be appreciated

There are no parental controls and this model has no QoS settings that I know of, Traffic meter is disabled
