This is almost exactly how my wireless backhaul behaves, but it's hidden so I only notice it when I'm using Wifi Explorer.

They all have the same 32 character SSID, but I'm quite certain it doesn't change, so I don't know what that's about.

They're labeled in nvram as:
wl2.5_ssid
wl2_ssid
wl_ssid
wlbp_ssid
 
Go back to stock firmware, and let's see what happens...

I still think OP is chasing ghosts here...

It's a reasonable concern especially since they were seeing some VPN stuff also get created, however I'm starting to suspect it is just a bunch of default stuff that gets dumped on but not actually used.

All the VPN stuff he showed is just the normal default values present in the firmware.

Bumped into this thread on my RSS Feed.
I see this thread is for Asuswrt-Merlin AddOns, yet to try Merlin, @sfx2000 suggested OP try stock. Well, I am and was.

Single unit.
RT-AX88U Pro
Current Version : 3.0.0.6.102_21514
Previous Version: 3.0.0.4.388.23110

What is mystery? (Just a guess.)
Note: BSSID vs SSID.
When I enable, Authentication Method: WPA3-Personal for 2.4GHz, I get the mystery 2.4GHz WPA2 SSID with the same BSSID as 5GHz WPA3 SSID.

Example, BSSID and SSID modified.
OS: Ubuntu 23.10 (Mantic Minotaur)

Bash:

The pro routers with advanced guest are different, probably part of that new feature.

If I had to guess, I think mystery SSID is intentional and related to this pop up when switching to WPA3-Personal.
Edit. I could try to verify later on if it would allow me to flash back to the Previous Version: 3.0.0.4.388.23110, where it didn't have new advanced guest features implemented. And to clarify, in my test, I never got past initial setting that are included above. So guest wasn't touched, created. I am aware that version has some CVE that was fixed in new version, Current Version : 3.0.0.6.102_21514
Considering the compatibility of AiMesh system and end devices, we
suggest you using WPA2-Personal. Do you want to switch to WPA3-
Personal ?
*If you encounter connection issues, please switch to WPA2-Personal
or check with the manufacturer(s) to obtain further info.
System Log - General Log
If I search for mystery 44:44:44:44:44:44 (duplicate BSSID), this is the only spot where it's duplicated, in proximity to each other. I don't know what it means, to me, it looks like a confirmation and not a duplication or creation of something else.
(time removed, it's the same to the second on all three strings, BSSID modified, because I don't know what should or shouldn't be shared)

I agree that this does sound like a reasonable explanation. Just need to confirm with @randomised that's he's using WPA3.
 
From a security stand, something is broadcasting, and you have no clue or control over it.
From a performance stand, the router is using resources to add noise?
 
I experience the same issue with my RT-AX58U. Did you manage to understand what is this ghost SSID?

For additional context see DnLS's separate posting here which may have a little more information about their issue:

@DnLS, What firmware is the RT-AX58U running? Are you using YazFi?

Thanks for your reply. It's my post, but unfortunately nobody has answered yet.
I'm running stock Asus WRT 3.0.0.4.388_24762.

So you are not running YazFi since you are running stock firmware.
