Configuring Our Wireless Internetwork - 0 views

DonDevis Charlie on 04 May 14

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.

DonDevis Charlie on 04 May 14

With a range of products that support IEEE 802.11a/b/g and soon "n" technologies, Cisco really does offer a pretty complete and impressive line of in-building and outdoor wireless LAN solutions.

Wireless Security - 0 views

wireless security is nonexistent on access points and clients. The original 802.11 committee just didn't imagine that wireless hosts would one day outnumber bounded media hosts, but that's truly where we're headed.

Open Access - 0 views

DonDevis Charlie on 04 May 14

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.

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.

WPA or WPA2 Pre-Shared Key (PSK) is a better form of wireless security than any other basic wireless security method mentioned so far. I did say basic.

The 802.11 Standards - 1 views

DonDevis Charlie on 27 Oct 13

"IEEE 802.11 was the first, original standardized WLAN at 1 and 2Mbps. It runs in the 2.4GHz radio frequency and was ratified in 1997 even though we didn't see many products pop up until around 1999 when 802.11b was introduced"
