Clients are getting frequently disconnected on 2.4GHZ Radio from R500 while its is running smoothly on 5GHZ in same network.Connected devices would disconnect frequently and new devices hardly get to connect.But no issue in 5GHZ.Any idea on what the issue could be?Also in some old devices with b/g it seems fine.Is there any way to disable n mode in vSZ for 2.4GHZ Radio?
