Just the ticket if you need a PCMCIA card

Charles M., Newegg
21 June 2012
  • Summary: These cards were sold in bulk to hospitals, schools, etc. Thus, there is a glut of them on the secondary market now and new ones can be found for a fraction of original price.
  • Pros: I needed to find a newer PCMCIA card for an older laptop in order to connect to a WPA2 encrypted network, and this gets the job done nicely. (May need latest drivers for WPA2 support, see cons) Works great with CentOS 6.2 Linux - kernel has driver pre-installed Site Survey Utility for Windows wor...
  • Cons: Cisco won't let you download drivers unless you have a service contract with them; buying the hardware is not sufficient reason to have drivers in their eyes. The driver disk in the retail box is pretty old (v2.1). I had to download the latest Windows driver (v4.5) from an offshore "repository".

Good card, bad price

Donald H., Newegg
5 April 2012
  • Summary: We were throwing out a few laptops at work, so I took three of them to keep. Each had this wireless card in it. XP didn't have native drivers, so it was pretty hard to get the driver file on the computer.. The cd drive didn't work, and I had no floppy drive I could put it on a disk!
  • Pros: Fast connection
  • Cons: Windows XP didn't have the built in driver PRICE PRICE OH WOW, THE PRICE

The card

Earl M., Newegg
19 March 2010
  • Summary: Someone got the smart idea to get 50 of these for are Panasonic laptops at work so we can get a better connection. Guess what, the dead spots are still at work and the cards dont get a better connection.
  • Pros: It works and is easy to install.
  • Cons: The thing sticks out too far in the lap top and it will snap off if you do not watch out. I have seen 4 so far.

Best wireless card

mwelu, Amazon

  • Summary: 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.

Great Wireless Card

S. J. Northrip, Amazon
12 September 2009
  • Summary: Bought this used and saved a ton of money. Have put Linux (Ubuntu) Distros on some older laptops and these cards seem to work very well for Ubuntu. Will probably be buying another one for yet another "Grand Son's" computer.

mis advertising

Peter Van Scherpe, Amazon

  • Summary: This bus card is offered bundled with an external antenna but it does not accept one. Just to be clear.... you can buy the external antenna with the bus card but there is no way to connect the 2 together.

  • Summary: It turned out I wanted this Wi-Fi device for my OLD XP laptop anyway. I just checked the product description, and it didn't make this clear.

This is a superb card. Period.

D.B. Spalding, Amazon
3 June 2009
  • Summary: 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.
