Anyone having trouble with the hAP AC3 and netinstall / TFTP PXE booting? I can easily get the device into etherboot mode, but it sits there spamming bootp or dhcp requests and ignores the response from my DHCP server, eventually timing out and booting back into RouterOS. I tried upgrading Routerboot to 6.49 and toggling boot protocol and backup bootloader with no luck.

All the usual stuff is covered - firewall disabled, direct cabled connection to Ether1, static IPs.

I did some more testing, netinstall does actually work fine, I just wasn't waiting long enough for the device to show up. There's something about the BOOTP response from tftpd32 the hAP AC3 does not tolerate, yet it works fine on the hAP AC2. I thought the hardware was mostly identical so this is a bit surprising. I'll play around with different BOOTP/TFTP servers and see if I can get something working.
