R8000 - Slow ethernet speed
There are multiple posts on the slow speed on this router but I did not find any that are similar to the issue I have. I have also tried most things listed apart from a factory reset as avoiding till...
the speedtest on the router isn't reliable (through the app). Reason why is it usually picks the closest server and not the fastest server. Its nice to have but if you have reasonably fast internet, its not reliable because you can't change servers.
I guess this is a final summary from me if any help to others.
The problem with the loss of bandwidth for me clearly looked to be the use of Access Control. Since turning it off without doing a factory reset my speed has been stable all week around 550Mbps. Which on an advertised 500Mbps connection is as about the best I am going to get. Today I turned Access Control back on and my speed test instantly dropped to between 250Mbps and 265Mbps. Turning it back off instantly back to 550Mbps.
I was really shocked how much of an impact the Access Control is on bandwidth. I prefer to have that on for Wi-Fi connections but there does not seem to be an option to do that and the overall impact on bandwidth is huge.
Thanks to all the replies that helped me get to the bottom of this. I will certainly be looking more closely at impacted throughput when security features are enabled on any future replacement for this router. I am already looking more at a wired only router and then using an access point for just Wi-Fi connections. Potentially more expensive but likely to be more secure.

for speeds greater than 250mbps the router needs cut through forwarding (ctf) to hit those speeds. When that's been disabled, it places the burden on the cpu and it doesn't have the power to hit much faster than that speeds. Services that disable it: qos, parental controls, access control, traffic monitoring.
Its why we usually recommend those be disabled. Occassionally ,some have had to fully factory reset and leave those disabled to get ctf to be re-enabled.What the heck good are the services if you have to disable all of them to keep the router from choking out your bandwidth? I have been using access control to control when my children have access to the Internet. With QOS and traffic control OFF, I WAS getting speed readings from 180-210 at a laptop wired directly to router. I am paying for 350MBPS. Xfinity technician has been out more than once to troubleshoot. We both determined hard wired speed out directly from modem was 350+. Software Speedtest through router admin interface also showed 350ish. But I was losing 130-170MBPS on the backside of router, regardless of port or cables (tried several cat6e) used. Once I turned access control and parental controls off, bam, 360MBPS. Why on earth would there be such an overhead to run these features? Surely Netgear knows about it and could address it.
