Activating 802.11n on the controller

I have an Aruba3200 with 32 AP-93 APs. I am trying to activate the 802.11n radio on the controller but do not see it as an option anywhere. Under the RF Management the only options I have are 802.11a and 802.11g radio profiles, nothing regarding 802.11n. How do I go about activating 802.11n?

It should work by default.  Why do you think it is not working?  802.11n is also dependent on your encryption.  Only Open and AES are supported for 802.11n.

You can also enable/disable support for HT or High Throughput...but this is also on by default.

Thanks for the replies. The reason I know it's not working is that I have a whole building full of wireless N devices, but when i go under clients, they are all connected as 802.11g-HT. Shouldn't they show up as 802.11n?

"HT" is shorthand for 802.11n  g-HT is 802.11n on the g or 2.4ghz band.  It means "High Throughput".

Re: Activating 802.11n on the controller

This leads me to believe that you are running a single radio AP, that is capable of being in EITHER 2.4 or 5GHz, in 2.4 GHz, and you will need to get  that moved over to 5GHz

Perfect, thank you! Is there typically any backwards compatibility issues for 11g devices when upgrading to 5GHz?

Re: Activating 802.11n on the controller

I'm not clear what you mean here. If you're device is only 2.4 GHz capable it won't see a 5 GHz signal at all. This will include your phones, some tablets, older laptops, game consoles, etc. Can you clarify what you're asking here?

Re: Activating 802.11n on the controller

Basically, my APs are single radio. So if i change them all from 2GHz to 5GHz does this mean that my wireless G devices will not be able to connect?

Yes, that's correct. You might want to check out the 802.11n VRD we published, http://www.arubanetworks.com/vrd.
