How to find information about the number of supported SSID's, mesh support etc

Installing and Using OpenWrt
1

I'm trying to figure out the following:

I currently have 3 AP's running Openwrt and freaking loving it.
However, I'm looking to replace one of them.

I have however a certain setup currently in place between those 3 AP's, such as I have them in a mesh and I also have the need for a certain amount of SSID's in the 2.4 and 5 GHz range, because I use those to breakout VLAN's.

However, I'm having issues finding out how many SSID's would be supported, if mesh would be supported etc. based on devices I find online.

Example: let's say I'm considering the TP-Link Omada EAP245 access point. OK, according to the Openwrt wiki, that device has certain WLAN hardware.
In this case: Qualcomm Atheros QCA9563, Qualcomm Atheros QCA9982
(according to: https://openwrt.org/toh/tp-link/eap245_v3).

But... where or how now can I figure out how many SSID's this device would support on the 2.4 GHz and 5 GHz band, if it would support mesh or not etc. before I buy the device and flash it with Openwrt, maybe to come to the conclusion that it doesn't support what I need?

Well two points to be answered first:

  1. What do you mean by a mesh?
    See: https://openwrt.org/docs/guide-user/network/wifi/mesh/802-11s#are_you_sure_you_want_a_mesh
  2. If you really mean "mesh", ie a wireless backhaul, by default, vlans are not supported. You need some form of peer to peer tunnelling for that.

Something like that?

OK, just to clarify, yes I mean that (802.11s) and my question is not if that is a good idea or how to do it.
I already have it implemented for 6+ months, it's working perfectly fine, and I'm using vxlan tunneling to get those VLAN's across the mesh.

My question is: where/how can I find the information about number of supported SSID's for 2.4/5 GHz, if 802.11s would be supported etc. depending on the device.

Yes, exactly, I know of this.
BUT... I'm looking for a new device. I don't want to buy a device, receive it at home, flash it, run the iw list command and then see that the device doesn't have what I need...

Can I find this information somewhere online, BEFORE I actually buy the device?

There is no definitive online list for this. If you already have the device you can run the iw command suggested by @AndrewZ ......

Maybe start a new thread asking people to run that command and post the results... It would make a useful source of information.

Here you can see what is supported by the drivers.
Browsing Techdata pages should give an idea of ​​the WLAN hardware used in a particular device.

OK, so you can get some info there, but still not really conclusive.
Example ath10, side note "only on some devices".
Also: no indication of how many SSID's are supported on both bands.
Basically best I can see is if mesh is supported or not.
