Thank you. I successfully flashed 21.02.1 for 4A Gigabit version.
Unfortunately I cannot get the ethernet working. I did a fresh install, not keeping any settings.
Now when I try to set it up it does not work.
I can log in to LuCI via browser (192.168.1.1) but when I configure the network (static IP address from ISP, DNS etc, same as before) I have no connection.
For WAN Interface settings the original value for "Device" was "wan". Did not work so I changed it to "eth0" but that does not work either.
192.168.1.237 DNS in LAN is AdGuard running on raspberry pi. Tried with or without, no luck.
Really don't know where's the problem.
Here is the screenshot of router current network settings (/etc/config/network) and the backup I created before flashing.
What am I doing wrong? (I did not set up wifi yet)
