Hi, my first message here... I have a ZenWifi XT8 pair, currently on 3.0.0.4_386_25524 public firmware... actually back to it after about an hour on today's RC4 beta. Just wanted to confirm that while both primary and secondary devices accepted the new firmware (dirty flash over public version, no factory reset) - there were several immediately noticeable issues:
1. Wireless clients cannot talk to wired clients... I've noticed it immediately as I have an iperf3 server on wired connection, which I routinely use to measure the true speed for WiFi clients - and I was unable to connect to it from any wireless clients. Pings are also not coming through... The wireless & wired clients did have perfect connectivity with Internet, but no comm between wired & wireless hosts, as if the wireless hosts are on a guest network where "Access to Intranet" is set to "Disable" (that is how I set a guest 5G-1 SSID for my employer's devices). So, I've tried to turn On and then Off again the "Set AP Isolated" for each of 2.4G and 5G-1 bands (I normally have it Off, but just in case... flipped it forth and back) - no effect, wireless is not able to talk to wired. I have wireless cameras and wired NVR for them - so, it's a show stopper for me.
2. Web interface seemed to be **very** sluggish, even after ~1 hour after install, I've tried both https and http URLs for it - both were very slow.
3. I have a portable Dell USB3.1 Gen2 SSD connected to the USB port (and it is set to USB 3.0 mode) - the speed on this RC4 have dropped about twice, and I think it wasn't great on public FW either (~40...45 MB/s over wired connection), but with this RC4 Beta it fell to ~20-25 MB/s. If I recall correctly I had much faster network storage speed with the same SSD drive on the RT-AC86U (which had died on its 2.4G side recently, got RMAed, but also got replaced with this newly purchased XT8 pair because we all work from home these days... no time to wait for RMA to arrive...).
4. I was unable to manually flash the remote node back to the public FW - the small browser window where you normally get a button to upload file was simply timing out, as if the web interface on the node was not responding (hint... web interface was very sluggish on the primary as well - same problem?). So, I had to remove the AiMesh node from the primary, reset it with WPS button method, bring it close to the main router and eventually - I was able to bring it into AiMesh again and then - reflash with public FW.
A side note - propagation of Guest SSID to the remote node worked, Guest SSID were broadcast from both the main and the remote node, on both 2.4G and 5G-1 bands - a good sign of progress. If only the #1 above would not be the case...
Finally, a few words on why I was still trying to use this beta FW - the public version keeps mysteriously drop 5G-1 speeds after a day or two, it drops from 300-500 Mbps (on fast-CPU 2x2 AC devices, measured with internal wired iperf3 server) to abysmal and erratic 10...60 Mbps. Powercycling of the main router fixes it. And scheduled reboot daily seems to minimize, but not completely eliminate the daily occurences. Hence, to keep my marriage going - I really hope this beta will quickly become a debugged, new public release...
All the best to Asus engineers, keep up the good work! And stay safe!

Might want to try a clean upgrade. I'm on RC4 and my wireless laptop and mobile phone can connect to my wired CCTV and NAS.
Dirty upgrade from RC3. Did have issues with reconnecting every 60 seconds until I removed the node and added it back.
When connecting to Guest it isolates from everything on the LAN & WLAN again.
(Guest is on 5ghz-2)
