This article describe how to disable the 5 GHz band on Instant Access Point (IAP) by enabling the extended SSID option.
In certain use cases, IAP using external antenna such as IAP-104, IAP-92 or IAP-108, administrators might want to disable the 5 GHz band as unavailability of compatible antennas or need to increase the number of SSID support on the 2.4 GHz band.
This article is applicable only for dual-radio IAP's.
- 5 GHz LED might show a green LED even after the radio is disabled.
- To disable 2.4 GHz band: Just removing its reference from SSID profile and restarting the IAP.
Environment : Aruba Instant version 6.2.0.0-3.2.0.2 and IAP-105 is used for all the sample output provided in this article.
Making a selection of 2.4 GHz band in the SSID profile will not disable the 5 Ghz band as this radio is also used for mesh-backhaul when Ethernet uplink fails.

Secondly, Create new SSID profile (or) Edit existing SSID profile to change the band to "2.4 GHz only"
