From the link below: https://www.stupid-projects.com/posts/nanopi-r4s-benchmarks-with-networking-optimizations/ The MTU size seems to be important too. With the commands: ip link set dev end0 mtu 512 ip link set dev enp1s0 mtu 512 The packet loss dropped from 15%-30% to 0%.

@whitefox, have you tested disabling the tcp-segmentation-offload and generic-segmentation-offload? If not, could you try? With the Nanopi-R4s it was the "Solution". It ins't performant, but work far best now. The packet loss is gone. Here are the lines to run: ethtool -K eth0 tso off ethtool -K eth0 gso off To verify: ethtool -k eth0 I hope it helps.

The command below seems to be the solution for this problem: ethtool -K enp1s0 tso off I have found this post, where the command was.

Hello everyone, I have a problem with my NanoPi R4S. The WAN (eth0) port does not work well when it is configured to work on 1Gbps/Full. When this setting is active there is about 15% packet loss, which is quite annoying. In my tests I have already been able to identify that if I configure the port to work at 100Mbps/Full everything works normally. So I found the forum-post below, that explain that some u-Boot version wasn't setting the correct clock configuration for the netwok device at boot time, but now I have installed the linux-u-boot-nanopi-r4s-edge 22.08.6 and linux-image-edge-rockchip64 22.08.8 but the problem still there. I've read millions of forums for the solution, and so far I haven't made much progress. Would anyone be able to help me? in dmesg it looks like: [ 1.853954] rk_gmac-dwmac fe300000.ethernet: IRQ eth_wake_irq not found [ 1.853967] rk_gmac-dwmac fe300000.ethernet: IRQ eth_lpi not found [ 1.854071] rk_gmac-dwmac fe300000.ethernet: PTP uses main clock [ 1.854234] rk_gmac-dwmac fe300000.ethernet: clock input or output?
