C7000v2 WAY slower than Xfinity modem
I just signed up for 600Mb Download speed from Xfinity.
I've BEEN using a C7000v2 with Xfinity for a while, but when I upgrade to the new speed I ran a speed test (WiFi) and get about +/- 260Mb.
With Xfinity's router, I'm seeing well over 600Mb down.
I'd LOVE to use the C7000v2. The Xfinity modem is LOUD and expensive.
Suggestions?

was the C7000 new?
did you enable or has qos been enabled? it isn't recommended >250mbps as it disabled ctf (cut through forwarding) which allows speeds >250mbps.
I've read of qos settings being retained even through a reboot. you could try factory resetting it. just make sure not to enable traffic meter or qos.
Another thing you could do is have them re-provision it. I've had them send the wrong provision file before.
Take a screen snip of your modem connections page. it shows the connection back to the isp. This helps check the signal
I'm pretty sure I bought it new, but it's been a while since I did.
As far as I've been able to tell, there is no QOS setting/option on this device.
Traffic Meter has been off the whole time.
I can't send a screenshot since the only way to get it is if the modem is active, which it's not at the moment -- Comcast/Xfinity won't let me have both devices active at the same time (and, obviously then, I'm using the Xfinity modem at the moment).
What are you wired speeds thru the NG modem?
Have the ISP check the signal and line quality UP to the modem.
Be sure there are not coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?I no longer own a computer with an ethernet port.
The Xfinity gives about 700Mb down via WiFi.
The NG gives about 260.
