Nighthawk R6700v3 maximum wired speed less than cable modem

Question

I've seen several similar threads stating that a firmware issue exists that prevents reaching maximum available speeds, so let me know if there is anything I can do here.

I have the current firmware installed (1.0.4.128_10.0.104) on an R6700v3 router. The problem seems obvious:

1) Connecting my laptop directly to the cable modem port gives my ~220 Mbps download via speedtest.net (I pay for 200).

2) Connecting my laptop directly to one of the ethernet ports on my Nighthawk R6700v3 gives me 150-170 Mbps.

I was considering bumping up my internet speed but if the router won't support it then that would be pointless.

I've powered off and restarted, I've never used QOS (downstream and upstream boxes are unchecked, both WMM boxes are checked), let me know if there is anything other than replacing this router that will fix it. Thanks!

Edited to add: I see a common suggestion is factory resetting, so I will try that when I'm off work. Just seeing if there is any other solution as that seems like a pretty non-user-friendly approach.

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.&nbsp;
&nbsp;
Try a factory reset and walk thru the setup wizard. Be sure to NOT enabled Armor, Access Controls, Circle, QOS or Traffic Meter.&nbsp;

Thanks for responding!&nbsp;Modem is my own, Arris Surfboard SB-8200.&nbsp; I'm 99% sure the cord is not the problem as I only use Cat 5e or better, but I'll swap in the cord I got 220 Mbps on my laptop just in case.&nbsp; Otherwise factory reset will be the next step.

Just wanted to follow up - the factory reset fixed the problem.&nbsp; Kind of a pain to have to do that, but I guess if it works...&nbsp;Too bad it doesn't just automatically fix itself after a normal reboot.&nbsp; Oh well, just wanted to post my results, my speeds are now matching when bypassing the router and when using a LAN port.&nbsp; Thanks all.

It does normally.
&nbsp;
A reset isn't needed most of the time. A reboot usually works.
&nbsp;
One thing you can try is to save the configuration before you update the firmware. Then if you have issues after an update you can reset the device and reload the saved settings..
&nbsp;
This can revive the problem you had before the reset, but it doesn't always. If the issue resurfaces, then you just have to reset again.
&nbsp;
In any case, you should always have a backup that you can reload for whatever reason.
