will turning off radio 2 (g/n) improve a wireless network

5Ghz band is a better than 2.4Ghz band. There are more non overlapping channels, and less interference from non 802.11 wifi devices ( like cordless phones, Bluetooth, etc ).

If you disable your 802.11 g/n radio, then it will force all users to connect to the 5Ghz band. You could also just not broadcast the ssid on the 2.4ghz radio though.

You could have 5ghz broadcast your apple tv ssid, and use 2.4ghz for other purposes, like guest access.

There is also a band steering feature you could switch on that would push clients that are 5ghz a/n capable to use that band.

It is true that a client roaming back and forth from 5Ghz to 2.4Ghz would not be ideal. You would be able to see if that is happening though from the gui.

Where is the setting to band steer clients to 5GHz?

Another apple tech thinks that too many devices are jumping on the g/n radio, which is slowing everyone else down. He thinks there are too many SSIDs being broadcast and causing interference. He says there are more channels in the 5Ghz band and only 3 in the 2.4Ghz.
The main issue we have is teachers not being able to mirror from their laptop/ipads to Apple TVs. I think it's an Apple issues, not a wireless network issue.

Hi Laura

As Pala asked what issues are you trying to solve?
By disabling radio 2 you will loose all your 2.4Ghz clients.
They will not be able to connect unless they have a dual band wifi NIC that will be able to connect to the 5Ghz radio 1.

One thing too look for at is what channels are in use in the area. The link http://en.wikipedia.org/wiki/List_of_WLAN_channels shows that there is a lot of overlap between channels. The more overlap, the more interference. For a given location, if you see strong channels which are numerically close together you are likely to see an impact to wireless network performance.
