Where you speed testing with a wired connected PC or wireless? Wire connected is preferred.
Last time i had mine on line at 1Gb I did see hear 900Mpbs speeds:

I don't have mine online currently as I'm running a CM1100 right now with two Orbi systems.

Possible there is a FW issue in recent updates or your system maybe faulty.

Furry,

Thanks for the reply, I think my system is bad, replacing it as we speak, CM600 and RBK50, going to be seriously annoyed if there is no improvement. All my spped tests were wired, 6a cable, changed out cables several times.

I would check with your ISP first to see if they support the CM600 at near 900Mbps on there system. Some ISPs require a DOCSIS 3.1 modem which the CM600 is not. I know for my ISP, they start at the CM700 including the CBK40(CM700 inside), however they prefer the CM1000 or higher. I have the CM1100 here for my 1Gb service. The CM1000 and up are all DOCSIS 3.1 modems.
