Raspberry Pi 2.4ghz Wifi Knocks Bulbs Offline?!?

I have a Cisco Meraki MR26 AP that the LIFX devices connect to. The Meraki is a (effectively) 2-radio system that supports 128 clients per radio. So I’m not hitting a limit there, and the LIFX connect to a Meraki-NAT network, rather than the main network, so they’re isolated and they can’t talk to each other.

I also have a Linksys VELOP 3-node mesh system that has everything else on it. I have not tried connecting the LIFX bulbs to the Linksys, since it’s new, but when I had all my devices on the Meraki, there would always be a couple that dropped off.
