I'm going to assume that you're not using wireless VLANs and that you're trying to configure WPA2-PSK rather than full WPA2. &nbsp;The WPA2-PSK isn't too hard, but fulll WPA2 is much more involved and required some supporting systems outside of the Cisco router. &nbsp;If you're trying to do wireless VLANs or full WPA2 with per-user RADIUS authentication, let me know and we can look at that. &nbsp;For no VLANS and WPA2-PSK, the configuration goes as follows:<br />
<br />
dot11 ssid Your-SSID<br />
&nbsp; &nbsp;authentication open <br />
&nbsp; &nbsp;authentication key-management wpa<br />
&nbsp; &nbsp;guest-mode<br />
&nbsp; &nbsp;wpa-psk ascii 0 Your-WPA2-Pre-shared-key<br />
!<br />
interface Dot11Radio0<br />
&nbsp;encryption mode ciphers aes-ccm<br />
&nbsp;!<br />
&nbsp;ssid Your-SSID<br />
<br />
The dot11 section defines the SSID and the WPA key. &nbsp;The Dot11Radio0 section tells the radio to use AES encryption and not TKIP encryption. &nbsp;TKIP versus AES is the primary difference between WPA and WPA2.

I am trying to enable/configure WPA2 on an cisco 850 series router.  I know it supports WPA2 but the site doesnt show me how to enable it.

How do i configure WPA2 on a cisco 850 router?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.
