This review is from: Cisco Aironet 802.11a/b/g Wireless Cardbus PC Card ( AIR-CB21AG-A-K9 ) (Personal Computers)

I have an older Aironet 350 802.11b card, and decided to upgrade to get the better range and speed that this card offers (not to mention full support for WPA-PSK AES; my 350 only supported WPA-PSK TKIP).

I couldn't be happier. The client utility software has been simplified and made elegantly effective, and the site survey utility (once an option, now included) is a terrific tool for scanning the local environs and identifying Wifi access points. For performance and connection reliability, I don't think you can find a better Wifi PC Card.

5.0 out of 5 stars Best wireless card, August 1, 2005

If you're looking for a wireless card that maximizes on signal capture, you won't regret buying Cisco. I bought Linksys, although cheaper, it was a joke, kept cutting off connection all the time. Although Cisco is more expensive, you pay for what you get. It was painful to have to buy another card but I don't regret spending a single dime on this card.

I've tried linksys, netgear, dlink, etc. but nothing competes with this card. I always lose my signal with those other cards but this one always has a solid signal. It's expensive, but well worth the money. It saves lots of frustration.
