Is it both the 2.5G and 1G Ethernet ports that do this? Have you tried using two 1G ports and leaving the 2.5G port unused? As long as the router is running the current firmware, v6.3.7.5, looks like a call to Netgear support is in order.

Thanks, I've tried to run wired connections in isolation + combination from all available ports.No difference unfortunately 😕

Hi, Very interesting test indeed. Check this out. This is consistent with the speeds I'm getting on fast.com + Speedtest (app and web, same results)Using this argument:iperf/iperf3 -c remotehost -i 1 -t 20 -rRun a test from remotehost to localhost Then I ran iPerf3 with a different argumentiperf/iperf3 -c remotehost -i 1 -t 20 -w 32M -P 4Run a test with 4 parallel streams, and with a 32M TCP buffer... and got better results: Not sure what conclusions to draw, or where to go from here?

    Hi,
    
    Very interesting test indeed.
    
    Check this out. This is consistent with the speeds I'm getting on fast.com + Speedtest (app and web, same results)
    Using this argument:
    iperf/iperf3 -c remotehost -i 1 -t 20 -r Run a test from remotehost to localhost
    
    Then I ran iPerf3 with a different argument
    iperf/iperf3 -c remotehost -i 1 -t 20 -w 32M -P 4 Run a test with 4 parallel streams, and with a 32M TCP buffer
    ... and got better results:
    
    Not sure what conclusions to draw, or where to go from here?

Has Armor or any SPC been enabled by chance on the RBR?
