So I have seen this issue repoerted in many previous discussions, with no answer. I have setup the Software Controller via docker on linux and I only every get a max of 41 clients showing up , despite there being > 70 on my network.

I have already tried to setup a new Software Controller on a different Linux device and get the same thing, 41 clients max. Even devices I know are online as I'm ssh'd into them dont always show up and/or I am unable to set a fixed ip to them as they are not showing up in the clients list. 

Performing a forget client only helps so much but the max of 41 never gets any higher.
