AX11000 long ping and big jitter on 2.4G network

Hello,
in my home network I use an AX11000 router as the main AP.
My network is setup as follows:
- Most of the heavy users are wired through a few switches to the AX11000
- The consumer devices (smartphones, laptops and similar) all use the 5 GHz network
- I have a some (very) thin clients on the 2.4 GHz, for IoT - less than 30 devices
I use powerline extenders with One Mesh, and I have great coverage all around my house.
As of lately, I noticed some of my IoT devices acting up, so I joined the 2.4 GHz network, and the network was unusable. I tried to ping the AX11000 from my laptop:
113 packets transmitted, 93 received, 17.6991% packet loss, time 112730ms
rtt min/avg/max/mdev = 3.989/932.114/3565.253/976.440 ms, pipe 4
As you can see, I lost 18% of the packets with a maximum 3.5 second response - something is most definitely going on. I then fired up LinSSID, which is a WiFi analysis tool for linux, and I noticed something extremely odd.
On the 2.4 GHz ch11, which is the one I have set, there is my network - the power I measured was around 30 dBm. On the very same channel, another network is present intermittently, the odd thing being that the ssid is composed by a bunch of \x00, I count 30 to be exact.
Now for the icing on the cake - LinSSID provides also the mac addresses of the networks it sees, here is what I found:
| MAC address | Description |
|---|---|
| 14:EB:B6:D8:CD:2E | My main 2.4 GHz network |
| 82:EB:B6:D8:CD:28 | The mistery `\x00` network |
| 82:EB:B6:D8:CD:29 | The guest network I activated |
As you can see, the MAC address of the "mistery" network is the AX11000 guest network MAC address, diminished by one. And of course it is very similar to the main 2.4 GHz network.
Further details:
- After I enabled the guest network, the problem seemed to be less prominent
- I now have rebooted the Archer, guest network is disabled, and it seems to work reasonably well
Can anyone comment/suggest further steps? I am very willing to perform further analysis and investigation, as I want to get to the bottom of this. This kind of performances from this router are unacceptable, and sould be fixed.
Many thanks for your time.
Ciao,
V
