constant reconnect to clients

[wredo]

Hello,
I'm using the Veyon Master (version 4.7.1.3) with in total 25 laptops which are connected via 2.4GHz WLAN to an access point.
When all laptops are running the connections are constantly appearing and disappearing. Quite randomly. I have tested it with 8 laptops and it was stable.

As example the users (here pcname) are constantly appearing and disappearing.

What could be the reason?

How much bandwidth would be needed in order to run 25 laptops simultaneously? Can the access point be a bottle neck?
Could such a "flickering" behaviour of the connections be caused by a too low bandwidth capability of the access point?

regards
Wredo
