Keyword: that support 802.11n should be configured for 802.11a/n mode for maximum speed and compatibility. Juniper Routers that only support 802.11a can be left in 802.11a mode. Different Wi-Fi Juniper Routers support different radio modes, so the exact setting will vary depending on the Wi-Fi router in use. In general, enable support for all modes. Devices will then automatically select the fastest commonly supported mode to communicate. Note that choosing a subset of the available modes will prevent older devices from connecting (for example, 802.11a devices will be unable to connect to a Wi-Fi router in 802.11n-only mode). In addition, choosing a subset of the available modes may cause interference with nearby legacy networks, and may cause nearby legacy devices to interfere with your network.
