You may congure the channels and power levels available for the AP’s enabled on the router. The router has a dual
band 802.11n radio, meaning either 2.4 GHz or 5 GHz frequency of operation can be selected (not concurrently
though). Based on the selected operating frequency, the mode selection will let you dene whether legacy
connections or only 802.11n connections (or both) are accepted on congured APs.
The ratied 802.11n support on this radio requires selecting the appropriate broadcast mode, and then dening
the channel spacing and control side band for 802.11n trac. The default settings are appropriate for most
networks. For example, changing the channel spacing to 40MHz can improve bandwidth at the expense of
supporting earlier 802.11n clients. The available transmission channels are governed by regulatory constraints
based on the region setting of the router.
To congure the radio settings:
1. Click Wireless > General > Radio Settings.
2. Complete the elds in the table below and click Save.
