I've lost conductivity to my KASA smart switches.
When I researched cause it became evident that the smart switches will only connect to a 2.4ghz network.
My Netgear Nighthawk C7800 sends both the 2.4 and the 5 ghz signal so the switches are unable to connect to the network (incompatible).
Question is- Is there a way to temporarily turn off the 5g network signal until I get switches connected?
Has anyone else encountered this issue? It seems to be a common issue when I trouble shoot smart switches.
Can you set separate SSID for the wireless or check if anything can connect at 2.4 the wireless might be faulty or the smart switch could be faulty
Can other devices connect to the 2.4Ghz Wifi? See if this page helps.
Having "lost" connectivity means you had connectivity...so it's not an issue with incompatibility.
Did you recently reconfigure something (router, switch) on your network? Any recent firmware updates requiring a reboot? Is your router configured to automatically change/optimize channel widths (20, 40, 80, etc MHz)?
If the switch is configured for 2.4, it'll only communicate on 2.4, unless, as Andrew noted, you combined the 2.4 and 5 into 1 network.

They should be separate SSIDs. According to my research, the C7800 doesn't have band steering. Are you using stock firmware? Or did you mean something different?
Good research on band-steering...now we can return to square-1.
What specifically is losing connectivity? Are there 3 devices in this process: switch, router and, for example, cellphone?
