SSIDs, WEP, and MAC Address Authentication - 0 views

DonDevis Charlie on 04 May 14

SSID is a common network name for the devices in a WLAN system that create the wireless LAN. An SSID prevents access by any client device that doesn't have the SSID. The thing is, by default, an access point broadcasts its SSID in its beacon many times a second. And even if SSID broadcasting is turned off, a bad guy can discover the SSID by monitoring the network and just waiting for a client response to the access point.

All Wi-Fi Certified wireless LAN products are shipped in "open-access" mode, with their security features turned off. While open access or no security may be appropriate and acceptable for public hot spots such as coffee shops, college campuses, and maybe airports, it's definitely not an option for an enterprise organization, and likely not even adequate for your private home network.

Wireless LANs (WLANs) use radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves. These waves can be absorbed, refracted,or reflected by walls, water, and metal surfaces, resulting in low signal strength.

I'd be pretty willing to bet you've heard the term VPN more than once before. Maybe you even know what one is, but just in case, a virtual private network (VPN) allows the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols.

MESH and LWAPP - 0 views

DonDevis Charlie on 04 May 14

As more vendors migrate to a mesh hierarchical design, and as larger networks are built using lightweight access points, we really need a standardized protocol that governs how lightweight access points communicate with WLAN systems. This is exactly the role filled by one of the Internet Engineering Task Force's (IETF's) latest draft specification, Lightweight Access Point Protocol (LWAPP).

Configuring through the SDM is definitely the easiest way to go for wireless configurations, that is, if you're using any type of security. And of course you should be! Basically, all you need to do to bring up an access point is to just turn it on. But if you do have a wireless card in your router.
