Thank you -your answer is thorough and likely will get at the root of the problem .
The netgear talks on the 192.168.0.X subnet - each router has its own address on that subnet , ie, 192.168.0.20, 192.168.0.30, etc. Each router in turn hosts is own subnet , ie 192.168.0.20's local address would be 192.168.20.1. Of course, each subnet has its own SSID and range of IPS, and each router's password is unique WPA2-PSK.
The channels are problematic though - there are 11 channels, and ch.1 bleeds as far up as ch.6, and ch.11 bleeds as far down as ch.6, so there will be overlap. But I will map out the office and the location of the AP's and see if there is something I can do to lessen the impact. I thought using dual band routers and the 5k range offers something like 50 discreet channels, so that is where I'm exploring if your points dont work. AP ISolation / Client Isolation is something I am not aware of - I'll look into it, and report back about what happens. Thanks again. and seasons' greetings.
