Slow speed using AC1750 (R6400 v1) router
Hello community. I'm struggling to figure out why I'm not getting nearly the internet speed I should be getting from my AC1750 (R6400 v1) router to my ISP (Comcast). Comcast increased my speed to 800mbps which was confirmed recently by a service tech at my home. My old Netgear modem did not support this higher speed and was no longer supported so I purchased a new Netgear CM2050V modem. I connected this new modem to my AC1750 router via the new ethernet cable that came with the new modem.
I have the latest firmware (V1.0.1.78_1.0.50) on the router. I use the Netgear Nighthawk app on my iPhone to log into the router and use the Internet Speed test function in the app. I believe this is testing the speed from the router to my ISP. I consistently get 375mbps, roughly half the 800mbps Comcast confirmed is coming into my home. I've read several other slow speed posts. I confirmed QoS is off and I turned off Traffic Meter which did not make any difference. I use to us Parental Controls but Netgear no longer supports that and I don't believe is in place.
I believe the AC1750 should handle 800mbps and is still supported by Netgear. Maybe it can't. Any thoughts?
Thanks. I am researching with Lenovo. My ethernet connected HP is now much quicker at the 900+ speed vs the 300+ speed I was getting. Factory reset of the router was the trick. I appreciate all the help!

Did I read correctly that the service tech confirmed that 800MB speed before the modem was switched out for the CM2050V modem?
One first step may be to connect an Ethernet capable device directly to the CM2020V modem and perform a speed test.
(desktop or laptop). It could be that the new modem needs to be provisioned by Comcast.
I did not try a factory reset of the AC1750 router after installing the new modem. I'll give that a try.
The reason I ran the speedtest from within the Netgear Nighthawk app is because I wanted to eliminate my laptop and its ethernet cable to the router as a possible cause.
I did run an Ookla Speedtest from my newer windows laptop ethernet cabled to my router which also shows an ~375Mbps download speed.
Lastly, the Comcast service tech just happened to be at my house for another issue after I had already installed the new modem so I asked him to verify the incoming speed since I was not seeing it via speedtest. His comment was maybe the router could not handle the speed.

"Maybe your router can't handle it" does not sound like verify.
How long will it take to connect the laptop directly to the modem and run a Speed Test?
If the laptop does not get more than 375MB directly from the modem, then the Orbi cannot, either.
a couple things.
1. try hardwiring a pc/laptop into the router to test it. The built-in speedtest isn't that accurate.
2. after the upgrade, did you try factory resetting and reinstalling the router? Always good to try after a speed change. Make sure to leave qos, access controls, traffic monitoring, and parental controls all disabled.
