The same thing happened to me last summer with a storm on an RT-AX58U, lan ports 1 and 3 do not work. The rest is fine, wan, wifi and lan ports 2 and 4.
Thanks to home insurance I solved the problem, and paying the difference I bought the RT-AX88U, leaving aimesh RT-AX58U.
I did that a long time ago but for the guest network. The image of the QR code, I took it from the Asus router mobile app, printed it and pasted it on a magnet.
As I have said before, it works perfect at least for me, I do not have or have had any problems. Asus RT-AX58U (FW Merlin 386_2_4) and Lyra MAP-AC2200 (FW 9.0.0.4.386.41615 RC2).
The Lyra MAP-AC2200 works perfect for me with this version of the firmware "FW 9.0.0.4.386.41615 RC2 (Aimesh 2.0)", since February, no faults, no problems.
ASUS Lyra / Lyra Mini / Lyra Trio Firmware versión 9.0.0.4.384_46629 Beta

Just what I expected to find! Works fantastic, at least on my Lyra AC2200. Let it take a couple of days at least to see stability.
Thank you very much once again Ligeza.
