I plan to get a serial connection on it this weekend to see exactly what happens, but with the easy TFTP recovery I've bisected it to the GCC 8.4 update. Doing a dirclean between each test, https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=db70077668e757a27f41d9cb3c84f28ea7d4c22e is the first bad commit. This is the simple config I've used for testing:

Thanks for this report. I'm not in the posession of an AC-Pro but i
have a WDR3600 around, which is mostly identical to the WDR4300.

I've not tested 5.4 there, but i will see if i can reproduce any network-related
issue there.

Best wishes
