Tenda AC9 can not install OpenWrt 18 to 22 series

Installing and Using OpenWrt
1

After I install 18 to 22 series, the Router fails to start. The network card is not assigned to an IP.
Installing the 17 series works fine.
How can the new series of the system run normally?

2

Tried upgrading from 17 to 18 ?

I tried. The same problem.

4

And it's not an AC9 v2 ?

5

How to check its version?

6

No idea, for this specific device, start by checking sticker on back/bottom.
