Unified Services Router User Manual broadcast the SSID for the VAP with WEP since it is meant to be used for a few legacy devices in this scenario. 4.4 Tuning Radio Specific Settings Setup > Wireless Settings > Radio Settings The Radio Settings page lets you configure the channels and power levels available for the AP's enabled on the DSR. 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 define whether legacy connections or only 802.11n connections (or both) are accepted on configured APs. Figure 34: Radio card configuration options The ratified 802.11n support on this radio requires selecting the appropriate broadcast (NA or NG etc.) mode, and then defining the channel spacing and control side band for 802.11n traffic. The default settings are appropriate for most networks. For example, changing the channel spacing to 40 MHz 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. The maximum transmission power is similarly governed by regulatory limits; you have the option to decrease from the default maximum to reduce the signal strength of traffic out of the radio. 62
