What do the radio mode settings in the last column mean?
This shows the list of our 3 SSIDs that we use.What is the difference between a/n/g and a/n/g/n-strict mode?
Does this mean any device with a "a" or "n" or "g" radio can connect to this SSID?

It's an overview of the different modes used on that service. For example if you only selected a radio that was configured for G/N then that column would only show G/N. When you are logged into the controller there is a help file on the upper right hand side of the GUI. You can search that for your rate questions. Example:


  • a — Click to enable the 802.11a mode of Radio 1 without 802.11n capability.
  • a/n — Click to enable the 802.11a mode of Radio 1 with 802.11n capability.
  • a/n/ac — Click to enable the 802.11ac mode of Radio 1 with 802.11ac capability.
  • ac-strict — Click to enable the 802.11ac mode of Radio 1 with 802.ac strict capability.
  • n-strict — Click to enable the 802.11a mode of Radio 1 with 802.11n strict capability.

Not sure whether it's a good idea to have "a/n/g/n-strict" as that would mean that you support 802.11g on some APs and some others are set to 802.11n (strict) and don't support 802.11g.

Could be an issue if a 802.11g only client likes to work in that area.

I didn't actually configure all the settings in the beginning. I am trying to fine tune and improve our wireless. Thank you for all the info.

I agree with Ron, the "strict" mode settings can cause issues if the client does not like the rates we are advertising. The "strict" mode setting is not a standards based setting, it's Extreme specific. While our intentions are good with that setting, it may not be compatible with all the clients out there in the marketplace today. Some Examples...

But what does "802.11n strict capability." mean? Does it just make it so only devices with an 802.11n radio can connect? And devices that use b/g/a will not connect?

That's correct, it means the client can connect at 802.11n rates only.
