# 1. Remove the lan6 port from the local LAN bridge configuration
uci del_list network.lan_dev.ports='lan6'
# 2. Assign the physical lan6 port to the IPv4 WAN interface
uci set network.wan.device='lan6'
# 3. Assign the physical lan6 port to the IPv6 WAN interface
uci set network.wan6.device='lan6'
# 4. Commit and save the network configuration changes to flash memory
uci commit network
# 5. Reload the network service to apply the changes immediately
service network reload
I use AI for help it. But i think that it include in openwrt wiki.

And use the board for set settings in LUCI, ssh, ping. It has 1G link from some other router.
Now i use WAN-sfp port with SFP to RG-45 1.25G reconnector. And it work good.
Now i use iperf3. Link is 1G. Wan-sfp with sft to rg45 reconnector. BPI r4 pro 4r is not SERVER.

@frank-w Write to me how i can SET wan-phy, please. I’m already confused with the interface names, sorry. I will test iperf3 with phy wan port. UPD1: Found the command:

Mhm,wonder why wan-phy has retransmitts
Btw. You can add -r switch of iperf3 to reverse the direction (leave server as it is) or --bidir for both directions
What do you mean? I can repeat the test.

Wan-phy is interface wan (eth1)…have you bridged this interface to br-lan too?
What does ethtool -s tell you after the retransmitts shown in iperf3?
You can see this in the previous logs.

yes and here the stats were interesting, somehow my wan-phy does not come up completely…do not know why yet. in my running system i see an sfp-property which should not be there in phy-mode…i do not see it in my dts{,i,o} files…i try reflashing.
I hope it will be help to you

mhm, after rebuilding and flashing i get a trace when bootup process tries to bring up wan…really strange…seems like something has changed…still do not see the sfp property on mac@1 in any dts{,i,o}
ah, it looks like i miss the phy driver/firmware in my current state…maybe i had it enabled manually
Symbol: PACKAGE_mt7988-2p5g-phy-firmware [=n]
Symbol: PACKAGE_kmod-phy-mediatek-2p5g [=n]
wonder why this happened because i have it enabled…maybe because switching between 4e and 8x board without distclean

already noticed, that the device-specific defaults are not taken when selecting another board (here R4pro 8x vs. 4e), not sure how to solve without distclean and rebuilding .config
but back to the retransmitts…i have them only in sending direction and less count than you

maybe caused by client/switch between client and server, or something must settle a bit…did a bidir after the first run which is completely clean (could be lower layer too - tcp window, MTU path discovery or such)

Have you used same cable,client,switchports for sfp and phy test? Could be pause/flowcontrol-setting on the way
1 Like
Just to clarify: in my previous test on wan-phy, I had 0 retransmits across all runs in both directions (Retr: 0 on TX and -R RX).
Regarding my physical setup:
- Cable: The exact same cable was used for both tests.
- Topology / Switch: BPI-R4 was connected through a 5-port 1 Gbps switch to the main router (AX6000 at
192.168.31.1). - Ports: The port on the main router (AX6000) remained unchanged throughout the tests.
AI think:
In your case, rx_flow_control_packets: 0 in ethtool points to disabled Pause frames. On a direct link or small switch buffers, microbursts easily cause buffer overruns during unidirectional TX, forcing TCP Cwnd to collapse (from 656 KB down to ~294 KB). In --bidir mode, incoming ACK pacing naturally smooths out the traffic bursts, which kept your Cwnd stable at 771 KB with zero drops.
UPD2:
I Checked Flow Control on wan interface with AI:
Autonegotiate: onRX negotiated: on/TX negotiated: onrx_overflow: 0rx_flow_control_packets: 0
In my setup, symmetric Pause frame negotiation succeeded with the intermediate switch. The absence of rx_overflow and 0 retransmits even under --bidir confirms the MT7988 PHY/MAC handles full-duplex line rate gracefully when Flow Control auto-negotiation is properly resolved by the link partner.
