Hello,
I have recently purchased a raspberry pi5 and I ran iperf3 to my pi4b, and I was showing full 1 gbps up and down, but when I use speedtest I get much slower speeds, I checked dmesg, and see that, flow control is not enabled.
From RPI 5 running RPIOS lite:
But on my raspberry pi 4 running ubuntu, it shows:
I also see that running lshw, that this shows what driver is being used, and I am wondering why it is running macb, and not some broad com driver.These are both plugged into the router right next to each other, I was thinking that this should work.
