White Switches becoming unavailable in Home Assistant

“Yes I updated but the problem appears to be tied to the 2.4Ghz channel I was using so I changed it in my router and it appears to have fixed things.”

This. Any additional information about changing/updating 2.4Ghz channel in your router? I’m not familiar with exactly what the word channel means in this context, such that it’s hard to know if my router even supports doing what you did.

The reason I’m asking is due to this attached chain. It seems to be a pattern lately of people having intermittent “unavailable” connectivity issues with the white series, such that their only apparent resolution is to pull the air gap.
