Integrated 802.11b/g Radio Module—Wireless Routers Only

The Cisco Secure Router 520 Series wireless router has an integrated IEEE 802.11b/g radio module that operates as a wireless access point in infrastructure mode. The wireless routers have one reverse-polarity threaded Neill-Concelman (RP-TNC) connector on the front panel on the right side. The swivel-mount, dipole, 2.4-GHz antenna, which is shipped with the router, connects to the RP-TNC connector to operate the 802.11b/g radio module. For more information, see the Cisco 2.4-GHzSwivel-Mount Dipole Antenna (23.7786.51) document.

You can configure the wireless operations by using the Cisco IOS command-line interface (CLI). For details, see the Cisco Secure Router 520 Series Software Configuration Guide.
