Blink cameras going offline

I have a GL-X3000 and connected Blink cameras (outdoor 4th generation), but they keep going offline and will not reconnect. Anyone else seeing this or have suggestions?

Are your camera using 2.4G or 5G wifi?
What is the encryption and channel?

Do you have the log of the router? Which may show the activities of camaera connection.

I think I figured it out after reading Blink camera Wifi compatibility guide. The GL-X3000 uses Wifi mode 11g/n/ax by default, but Blink cameras require 2.4G at b/g/n. So I changed routers mode to 11b/g/n and all the cameras started to work. Yippie.
