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

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 thent.
You can configure the wireless operations by using the Cisco IOS command-line interface (CLI). For
