Hello,

I've just did the firmware upgrade on my archer ax53 to the beta version 1.4.3 Build 20250314 rel.78903.

This version should support Ethernet backhauling.

And indeed when I look on my main router archer ax53 v2 I see that "ethernet backhauling" is connected

If i do speedtest on the satellite ax53 v1 with the beta firmware, I get a max speed of 100Mb/s on 5ghz (2402/2402)

However the routers are connected directly to each other with a Cat 6 cable and the tool shows the following:

If I unplug the cable the satellite router archer ax53 goes to wireless backhauling.

Speed on 5ghz (2402/2402) goes to +/- 500Mb/s what is acceptable.

Why is speed so slow on ethernet backhauling?

Both routers are directly connected to each other without a switch in between.

Kind regards
