With 16 properly configured non-encrypted stations, running with

However, I do continue to see DMA warnings such as these (I had picked up my
portable phone, and it knocked all the interfaces offline ..here
they are coming back up after I hung up the phone).
Is there some theory as to why using multiple interfaces cause so many
problems with DMA?
Seems pretty directly related to channel changes and/or resets, and exacerbated
by other interfaces sending data while another is scanning, for instance.
Other issues we've found in the past have been various races that you wouldn't
normally see with a single VIF.
Thanks,
