Product Description
Product Description
The D-Link DWL-G122 802.11g Wireless LAN USB Adapter is a high-performance 802.11g wireless LAN USB adapter that connects your computer to a high-speed wireless LAN. This adapter simply plugs to your computer through a fast USB 2.0 interface to provide up to 54Mbps wireless speed. With industry standard interoperability, backward compatibility with 802.11b devices and plug-and-play installation, this adapter is an ideal solution for notebook and laptop PC users needing fast and standard mobile network connection.
Up to 54Mbps Transmission Speed
The D-Link DWL-G122 provides speeds of up to 54Mbps when used with other 802.11g wireless devices. This compares favourably with 802.11b adapters that offer only 11Mbps transmission.
Compatible With 802.11b
Like the 802.11b devices, the DWL-G122 uses a single 2.4GHz wireless frequency, eliminating the complexity of dualband networking. 802.11g's compatibility with existing wireless LAN standards means that you do not need to change your entire network to maintain connectivity.
Easy Migration to Higher Bandwidth
By maintaining compatibility with your existing wireless network equipment, this adapter lets you upgrade to a higher speed at the pace you want. The D-Link DWL-G122 and other 802.11g standard devices can be gradually added to your network, while the rest of your older network remains perfectly connected.
Network Security
The DWL-G122 supports Wi-FiTM Protected Access (WPA) to provide the necessary security protocols and tools, so you can communicate with other wireless users confidentially, access sensitive information or send data that is dynamically encrypted as it's sent. WPA allows authorization and identification of users based on a secret key that changes automatically at a regular interval. Used in conjunction with a RADIUS server, WPA uses TKIP (Temporal Key Integrity Protocol) to change the temporal key every 10,000 packets. This insures much greater security than the standard WEP security, which requires the keys to be changed manually.
Fast USB 2.0 Interface
The DWL-G122 is equipped with a fast USB 2.0 port and a USB cable that connects to your computer, providing data throughput at up to 480Mbps between the network adapter and the host computer. That is about 40 times faster than the earlier USB 1.1 specification, allowing you to take advantage of the high 54Mbps wireless speed that this adapter provides.
With USB hot swap and plug-and-play capabilities, the DWL-G122 provides you with fast and easy connectivity to wireless devices and users, no matter if they use the 802.11b or the fast 802.11g standard.

Had this product for a few days now, brilliant compared to the Belkin one I had before. Belkin did supply Vista drivers but the thing didn't work that's for sure, it gave about 2 bars signal.
This D-Link is in a different league, Plug in, looks for drivers and installs automatically, then once your connected Windows update supplies the latest drivers which actually work! No worries at all for a change!
Still working, full signal, couldn't ask for anything more! WELL DONE D-Link!

Bought this along with a D-Link DSL-G604T router. I've given DWL-G122 adaptor two stars as it is a really good product when it works but D-Links support is awful. I have had this product for just over a year and I do take care of my computer items.
The positive: It worked well with my laptop for the first 4 months - easy to install, picked up a good connection in the house and had no clashes with XP.
The negative: However, it just stopped working my computer and any other laptop refused to see it when connected. I have since spent many hours on the phone to D-Link with each call I have to repeat the same procedure with my computer which takes considerable time and then they send me to their FTP to download new drivers and it doesn't work I have to go on and do it all again 6 months later I'm binning a faulty adaptor nothing to do with drivers!
The verdict: If it works and you've got some computer software knowledge to fix any problems yourself I think this product would be superb but if you might need support, in my experience, don't touch D-Link.

I've had this adpater for a long time now, lags out every 30 seconds or so for 2-5 seconds, when searching the Internet you don't notice, but when your playing a Online game its a killer, stresses you out, and even with updates and reboots and even moving around it still lags out.
Poor show, this adapter is for workstations only.

Inexpensive and works well
I used this to replace an old PCMCIA card using 802.11a.
This runs 802.11g at 54 Mbps so is much faster and it seems to pick up the signal better. Read more

This item is great, when it works.
Alas for some unknown reason after 6 months it just stopped working completely
A waste of money for me, be aware.
