Hi,
After changing some settings on my 2.4 GHz Band, Wi-Fi clients begin disconnecting from AP (2 GWN7610 and 1 GWN7602).
After many tentative ways to resolving the problem, including soft reboot and hard reboot of APs the problem didn’t resolve.
I discovered that SSID was broadcast after each reboot but then disappeared.
Finally, I created a new SSID with a new name on 2.4 GHz band, and clients could connect again.
So, to resolve I simply delete original SSID, and renamed the new one with the old name and all clients connected again to 2.4 GHz band.
Something corrupted on SSID configuration, only by creating a new one the problem was solved.
