How to configure band selection in Aruba Virtual Controller
Description:
Service Set Identifier or “SSID” is the name of the wireless network. SSID allows users or devices to connect to the desired network when multiple independent networks operate in the same physical area. Frequency bands are ranges of radio wave frequencies used to transmit data in the wireless spectrum, and can further be broken down into WiFi channels. (The higher the frequency, the faster the data transmission and shorter the signal range.)
Investigation:
Filter SSIDs and then check to see if multiple bands are using the same SSID.
Mitigation:
Configure an SSID for only one band when possible. Typically, each wireless band for a network would have a unique SSID for each band (2.4ghz and 5ghz). For example, one network may have the SSID of “Wireless” for the 2.4ghz band and “Wireless-5G” for the 5ghz band.
