Problems with Prism in Beta

When using the v2.9beta14 and Prism cards in the AP mode, a significant minority of my wireless customers would not connect. I downgraded to 2.824 and the problem went away. Has anyone else experienced this problem, or is there a fix to it?

Please make a supout file after you see the problem in v2.9 and send it to us so. support@mikrotik.com
