[Solved]Can't install openwrt on Powerbeam 5ac 620

Installing and Using OpenWrt
1

Hi,
I have an Ubiquiti device that I want to install OpenWrt on, but it's not working. I've followed this guide and flashing with the patched fwupdate.real is successful. However, after rebooting, I can't ping the device on 192.168.1.1.
I've downgraded the firmware to XC v8.7.4 and XC v8.7.0, but the problem remains. I also tried using TFTP, but the device doesn't accept the factory firmware from OpenWrt. I used the PowerBeam 5AC 500 image because I believe it has the same specs as my device.

Can anyone help me or point me in the right direction to resolve this issue?
Thanks.

I've compared the OEM boot log (airOS 8.0 RC2 dmesg) provided on this page for the Ubiquiti PowerBeam 5AC to the one I found in the device's temp directory named Boot.txt, and they seem identical.

What is this page you are mentioning? The forum? A device page?

Looking at the ToH there a couple of variants and you probably flashed a firmware which does not work on your device: https://openwrt.org/toh/ubiquiti/powerbeam_5ac

Which image did you flash?

After closely examining the boot log, I noticed some details I initially missed.

The specs for both the PowerBeam 5AC 500 and the PowerBeam 5AC 620 are the same, but their network ports are different. The PBE 5AC 500 uses the Atheros AR8031, while the PBE 5AC 620 uses the Atheros AR8033.

After researching the technical data for Ubiquiti devices, I found one that matches the PBE 5AC 620.

For others who have the same device as mine (PowerBeam 5AC 620), use this NanoBeam 5AC 19

So you mean this device: https://openwrt.org/toh/hwdata/ubiquiti/ubiquiti_nanobeam_ac_19?
Forgive me for being dense but it looks like you post a link but it is only cursive, blue-colored text.

Yes the links do not work.
There is a very incomplete wiki page about the Powerbeam 5AC but it only mentions the 500; these notes about the 620 should be added there.

Ubiquiti has many models which are the same hardware platform except for a different type of antenna.
