OpenWRT 19.07 works (https://downloads.openwrt.org/releases/19.07.8/targets/ath79/generic/openwrt-19.07.8-ath79-generic-ubnt_bullet-m-xw-squashfs-factory.bin)
OpenWrt 21.02 or master doesn't (tftp flash or sysupgrade)

(need to find my serial cable now)

Same here. After upgrading to OpenWrt 21.02.1, with the configuration discarded, the Ethernet port never turned on (except briefly during boot, for recovery). I used TFTP to recover. See also https://owenh.net/bulletm2hp.

I am running into this issue. If I configure the radio in AP mode, then upgrade from 19 to 21.02.2, I can connect and inspect the system. The ethernet link is up and DHCP offers are going out, but no ACKs are received. I wonder if there is a broken firewall rule.

The output of ip link shows that the ethernet interface is up.

I tried the 22.03.0-rc1 release and had the same issue. Going back to 19 for now.
