Product Description
Amazon.com Product Description
Amazon.com Product Description The Linksys Dual-Band Wireless A+G notebook adapter lets your notebook communicate with all three wireless network standards: 802.11b, 802.11a, and 802.11g. Typical 802.11b networks have a data rate of 11 Mbps, and are commonly found in corporate environments and in homes for household Internet connectivity without the need for running cables. They're also popping up all over the country in coffee shops, airports, hotels, convention centers, and other public spaces offering Internet "hot spots" to mobile users.
In high-speed or heavy-usage environments, 802.11b is quickly being replaced by 802.11g, which uses the same 2.4 GHz radio band, but at 54 Mbps--almost five times faster. The third wireless network standard is 802.11a, which also runs at 54 Mbps, but operates in the less-crowded 5 GHz radio band. Corporations are the most common user of 802.11a networks.
Whichever standard you use, the Dual-Band Wireless A+G notebook adapter is ready to connect. And it's simple to use. Just pop it into a PC Card slot and run the included Setup Wizard, which will walk you through the configuration. All wireless communications can be protected by up to 152-bit encryption, so your data stays secure.

See a comparison diagram of the different wireless technologies. | Wireless networks are rapidly becoming more popular and coming down in price. Since they don't require cables, you can use the devices anywhere in an office or home, even out on the patio. There's no need to roll out an Ethernet network cable to each room of a house; you can network anywhere--without wires. Outside the home, wireless networking is available in hotspots at coffee shops, businesses, and airports--great when you're on the road and need to get some work done. For convenience, wireless networking is the answer. Basically, a standard is a set of specifications for a device. All devices that follow a specific standard share operating characteristics, such as the radio frequency used and maximum data transfer speed.

Stick w/ WPC54G card if you have only have G network,
By MyPenName (Florida) - See all my reviews
This review is from: Cisco-Linksys WPC55AG Dual-Band Wireless A+G Notebook Adapter (Personal Computers)
I have a Linksys WRT54G wireless G router and I have tried it with 2 card offerings from Linksys - the WPC54G (for 802.11 b/g) and the WPC55AG (for 802.11 a/b/g). I can honestly say that with my router (w/ latest firmware version 1.02.1) I have had very strong streaming connection w/ the WPC54G card, not so with the WPC55AG. Using the a/b/g WPC55AG, the connection was significantly weaker and I would lose connection at the same distance. My desk is about 20 paces away from the router as the crow flies, (ie: other end of the 2 bedroom condo). Here is a pic of the 2 cards side by side: http://....In conclusion, I would NOT recommend the linksys WPC55AG card if you DO NOT have to connect to a 802.11a wireless network. I purchased the Linksys WPC54G laptop card and WRT54G wireless 4 port router on Amazon for $...(UPS ground shipping included). I purchased the Linksys WPC55AG laptop card for $...(SHIPPING included) on ....com. Their price unfortunately has since gone up ($...), but I was happy w/ their service. I received the product 5 days later via FEDEX. Look up WPC55AG on http://www.....com for the best deal. Enter your ZIP to see the bottom line price including shipping. One last tidbit, you could always go to Best Buy and purchase both cards to test them out for yourself. You are allowed to return the product withing 14 days. CompUSA will also probably have the product but imposes a restocking fee :( Hope this was helpful. - vw

Fine, but do you really need A?,

This review is from: Cisco-Linksys WPC55AG Dual-Band Wireless A+G Notebook Adapter (Personal Computers)
I purchased this card to complement my WRT55AG, dual-band router. I've not had particularly good luck connecting in A mode; in fact, I rarely use it because it's unable to maintain a solid connection. I don't know if this is the hardware or just life with "A", but I would not recommend using it in a residential setting. Save the bucks, stick with G/B.On the other hand, I"ve had no problems connecting to G (which I use at home) or B (on the road). The supplied software is pretty good for helping identify and select new networks, though it does take a few minutes to switch to a new network. Summary: unless you have a compelling reason, just stick with B/G.

Gets the work done,
By Shiya (San Francisco) - See all my reviews
This review is from: Cisco-Linksys WPC55AG Dual-Band Wireless A+G Notebook Adapter (Personal Computers)
I am very satisfied with this wireless network card. It is much easier to configure than my last network card. It is able to detect the networks right away. The connection is fast. The only drawback is when leaving the "Autodetect" of both network speeds on (for the A and the G networks speeds), it takes about 30 seconds to figure out the speed. But if I disable autodetection, it works in just a few seconds. I guess you just have to remember to switch the network protocol/speed when getting to a different wireless network, but still this feature is very nice to have in the case of occassional visits to customer sites and coffee shops.
