Enable Dynamic Channel Assignment
Step 5 Make sure that the wireless 2.4-Ghz and 5-Ghz networks are shut down, as described in the “Disable
Low Data Rates” section.
Step 6 Enable Dynamic Channel Assignment (DCA) on both the 2.4-Ghz and 5-Ghz wireless spectrums to
optimize channel assignments on radios for interference-free operation. For the 5-Ghz spectrum, enable
channel bonding to increase throughput.
DCA uses over-the-air metrics reported by each radio on every possible channel and provides a solution
that maximizes channel bandwidth and minimizes radio frequency interference from all sources: self
(signal), other networks (foreign interference), and noise (everything else).

Associate WLAN Clients
Step 7
Association of WLAN clients is done on the end-client device by choosing the appropriate SSID and
supplying the required credentials for authentication. Client connectivity depends on the type of device
used which can be verified by looking at the wireless network interface details.
