Ok, thanks for the feedback.

In my case, it appears there must be an AP at the edge of our range because
sometimes vAP want to switch channels, and sometimes not.  I do not have any good
way to automate configuring the vAP to work together well when some vAP may
switch channels, as far as I can tell.

I can understand why you would not want it upstream though.

Thanks,
Ben
