Thank you for your joining our Intel ® community.
As you may know, based on the Frequently Asked Questions about Intel® Wireless Adapters , our Wireless Adapter support a maximum of 8 clients on a hosted network.
The reason behind this is to avoid system instability.
Technically you can connect more than 8 clients; however the performance of the Hosted network will decrease, causing issues related to the connection.
Please let me know if you happen to have another inquiry.

I contacted Intel at: linuxwifi <email@example.com>
This was our summarized correspondence:
We currently use Linux on the NUC5 with our own half-height Atheros M.2 wireless adapter that we have tested to support multiple-dozen of wireless clients.
We were considering upgrading to the Intel NUC8... which comes with a soldered-down Intel® Wireless-AC 9560 + Bluetooth 5.0 M.2 card. (NUC8 has one less M.2 slot as a result)
I would like to know how many clients the IW AC9560 card can be supported in AP Mode (Access Point Mode).
We can support up to ~12 clients.
How can that max 12 clients be increased?
Is there a licensing option to open that up?
This is a firmware / hardware limitation. So no. No secret password, backdoor, etc
I don't understand how my linux server on a NUC box will experience system instability if more than 8 wireless clients connect to the Intel Wireless Adapter in AP mode.
We currently have multiple-dozen wireless clients connecting to an M.2 Atheros Wireless Adapter in AP mode, and the Linux system has never experienced any issues.
