Unifi AC HD ethernet problem

[SurrealColin]

Hello!

I've been successful installing an a couple of AC-PRO.

But now trying to install 22.03.2 on a AC HD.

Flashing goes as expected but when I reboot into OpenWRT I get severe packet loss pinging 192.168.1.1 and the LuCI Web interface is unusable. Same setup locally wired to a PC is stable when I revert to Unifi software.

Any suggestions what to try next? Older version, a snapshot?

I did notice it doesn't have an internal switch but instead uses the AR8033. Could it be something to do with that? I tried looking at release notes and commits but wasn't exactly sure what to look for.

Thanks

Does this device have a problem with the AR8033? I can't reach gigabit speed.

Unifi HD wired low speed, high CPU usage

Hi, as you know unifi hd has IPQ8064 SoC, it has two ethernet ports. Using an older device, the Zyxel NBG6716, I can get 950 megabits of speed from the wired ethernet port, while I can only get 500 megabits of speed with unifi HD. And in the meantime, I see that the CPU usage is 100%. Wifi is off, firewall is off, dnsmasq is off, there is automatic dhcp assignment, I performed the test as a switch. What is the reason why such a powerful device cannot exceed 500 megabits between two ethernet port…
