Thanks for the reply
Yep the AP has a static out of the DHCP range, NAT was off as well.
I tried giving the laptops a static ip and that worked connecting to the Zoom but this is not ideal as we need the wifi to be DHCP (from our server).
I'm going to send the AP back, Zooms customer service haven't helped any, will exchange for a different Access Point.
Does anybody know a decent AP? Is the Netgear WG602 any good?
