I did some research into my home network tonight and found out my 'smart bulbs' were borking my gateway, trying to reach out.
Time to roll back to traditional soft light LEDs.
Yeah, mine were Feit bulbs but popped up on network as wlan0 and Hangzhou. Swapping them out solved my issue.

I like Shelly lights. They can be switched to an mqtt mode that takes them offline. That or z-wave and ZigBee with a hub.
SonOff reloaded with tasmota is good too.
