LAN connections broken after upgrading Firmware - Archer BE550
My Archer BE550 got upgraded yesterday to version 1.2.2 Build 20251209 rel.57736(4555). Since then, my LAN connections are not working anymore ( 1 Windows 11, 1 Mac, 1 TV).
Sometimes I manage to make it work by powering off/on. The connection with the router is fine, but the browser keeps waiting forever to load the web pages. The wifi connections are fine.
I rely on the LAN connection for my work, so this issue is critical for me.
Thanks.

@Dast Where can I see the logs? Is that in the app or only via the web interface?

@icruces Just had the same thing, happened this afternoon and again this evening, I searched for the release of the firmware and this post was at the top.
I've just rolled back to the last version I could find on the tp link site and we're up and running again now.
