If thenĮcho "$PRIMARY_INTERFACE reconnected. #Reset USB device on disconnect to fix switch problems:ĮTH1UP=$(cat /sys/class/net/$PRIMARY_INTERFACE/operstate) UpSeconds="$(cat /proc/uptime | grep -o '^\+')" After hours of testing, I came up with a solution of monitoring the adapter status, and restarting it when the link is down: Since ip link set eth1 down sleep 5 ip link set eth1 up and other adapter restart commands didn't work, I noticed that when the realtek-r8152 drivers are being reinstalled, it unbinds the USB device. I noticed, that I can workaround this issue by re-building the realtek-r8152 drivers. The new NAS is a self-built Odroid device with an external USB3.0 2.5Gb ethernet. Putting the old NAS to the QNAP switch could workaround the speed issues, only in this rare scenario when I would be copying files from both NAS devices at the same time, but I still wouldn't be able to copy from the new NAS and download something from Internet with the full 1Gb/s speed at the same time.Īnyway, I found a workaround for this issue in my new NAS. Since the old NAS is only 1Gb/s it would be a slot waste, and such an expensive router like GT-AX6000 should theoretically route from it with no issues. I use two more ports of the QNAP switch for other devices. Thank you for the answer, but it's not a solution. Is it possible that it's some bug in the firmware? I'm using the newest Merlin: 388.2_2_rog. ![]() I'm really confused and I don't know how to test it. This was not happening on my old (bad) router: Xiaomi AX6000 with 2.5Gb/s LAN port. ![]() Then, after the switch power cycle, after some GT-AX6000 reboot, or after some time - the bug starts occurring again, and the transfer from NAS 2 always goes by the router instead of Switch -> PC. Unplugging the New NAS ethernet for 1 minute doesn't fix this issue - only the full reboot. So after I reboot the new NAS, I am getting the full speed of 2.5Gb/s on my PC. I only managed to fix it by rebooting the New NAS. Router restarts, PC restarts, multiple switch restarts, or executing ethctl eth5 phy-power down in Router SSH doesn't fix this issue. Then, data transfer from the New NAS to My PC goes by the GT-AX6000 router, instead of directly from the Switch. It maxes at ~1.6Gb/s, and either slows down the transfer of one of the NASes, or doesn't give the full speed on speedtest.Īfter trying dozens of different things, I noticed that the problem starts when I power cycle the QNAP QSW-1105-5T switch (unplug / plug the power). I noticed, that I can't get the full speed of 2.5Gb/s on My PC when I'm copying files from the Old NAS, New NAS and doing a speedtest at the same time. eth5: Unmanaged QNAP QSW-1105-5T switch (2.5Gb/s).I got a new Asus ROG Rapture GT-AX6000 router. ![]()
