I just read the release notes, in particular, the 'known issues and regression' and noticed that it is not listed that ports 3 and 4 on OpenWRT version 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a do not work. That means, plugging an Ethernet cable into them does not provide a connection.
This issue is being worked on in the upcoming release: 22.03.0-rc6 r19590-042d558536 / LuCI openwrt-22.03 branch git-22.204.42822-9a18337, where the lan ports in question presently work, but where wifi and ssh do not work. it is possible to create a wifi network via luci but connecting to it is not possible. all attempts at ssh connections are rejected with a bad password, though the same password is used in luci and works.
These would mean the last fully working version of the firmware on these boxes is 19.0.
On a side note, the firmware recognizes by box as a V2 even though this is not printed on the box.
Question: any plans to resolve the port issues on the 21.02.3 r16554-1d4dea6d4f / release?
