Digital Cameras Photo Reviews of D-Link DWL-G520 Wireless PCI Adapter, 802.11g, 108Mbps

Customer Review: Doesn't work well with Windows 98 SE
Summary: 2 Stars

My Dell Dimension XPS 400 Windows 98 SE has the Linksys WMP54GS card in it and it works perfectly. (The first time I installed it!) This computer has a modem and didn't have a wired ethernet card.

After trying the D-Link DWL-G520 AirPlus Xtreme G Wireless PCI Adapter 108Mbps card, which worked only once (after disabling the Dial Up modem) the Linksys card was the only card that the computer recognized, didn't freeze up during boot, and that connected to the wireless router the first time.

With the WMP54GS, the dial up modem is still installed and enabled.

I didn't have such good luck with my Compaq Deskpro P500 Windows 98 SE computer.

This card stopped the computer during boot up, even before the screen shows the memory test. Something very serious happened during the bootup sequence that locked up the machine.

It appears that older computers, especially Compaq, have unique charateristics that preclude using newer cards (read: cards with higher speeds). It might be in the BIOS that recognizes cards, it might be bus speed, it might be the use of PCI connector pins, it might be the operating system, it might be the incompatibility with the cards driver. I don't feel compelled to diagnose what is wrong.

After 3 weekends trying to get the D-Link DWL-G520 AirPlus Xtreme G Wireless PCI Adapter 108Mbps card to work in the Compaq, I bought and simply tried several major brand cards (Linksys, D-Link, Netgear) for 54 Mbs and 11 Mbs until I found one that worked. That card was the Linksys WMP11. It works perfectly. (The rest are being returned - sorry about that AMAZON.)

An installation quirk: In the Compaq, using the Linksys WMP11, I had a strong signal, and it reported it was connected to the Internet. but my computer couldn't connect to the internet.

I determined that the wired Ethernet adapter in the Compaq was causing a problem, and capturing during bootup the TCP/IP connection before the wireless modem had a chance.

The way I checked what was connected to TCP/IP in your computer is to RUN winipcfg and see what is in the dropdown box. If the WMP54GS or WMP11 (or whatever wireless card you installed) description isn't there, then the computer can't use it to connect to the internet.

The dial up modem is still installed and enabled in both computers. That did not stop the WMP11 in the Compaq or the WMP54GS in the Dell from working.

HINT: The wired Ethernet adapter is no longer in the Compaq. I am saving it though because that wired adapter is the one I used to connect via hardwire to Comcast, and it has the MAC address that I cloned into the Linksys router. I'll reinstall it and connect it to the router if I need to re-do the setup for the modem to the Comcast internet connection.

Looking back, it appears that the newer wireless lan cards are throughly tested on Windows XP and Windows 2000 computers (the install is usually much easier according to my wealthier friends) and minimally tested on Windows 98 SE and Windows ME computers.

Linksys apparently spent the time debugging the drivers and the resident modules on Windows 98 SE so it knows how to handle an existing dial up modem.

D-Link apparently didn't. For the D-Link DWL-G520 AirPlus Xtreme G Wireless PCI Adapter 108Mbps card(the only high speed card for which both computers booted up successfully at least once) I had to disable the modem (entry in network and modem in My Computer - Devices)to get it work at all, albeit fitfully and ultimately not sufficiently to serve its intended purpose.

Description of D-Link DWL-G520 Wireless PCI Adapter, 802.11g, 108Mbps

The D-Link AirPlus Xtreme G DWL-G520 PCI Adapter is a wireless PCI adapter featuring the latest technology to deliver data transfer rates up to 108Mbps in the 2.4GHz frequency. The DWL-G520 also works with 802.11b-compliant devices and when used with other D-Link AirPlus Xtreme G products delivers throughput speeds capable of handling heavy data payloads including real-time MPEG video streaming. Plus, the DWL-G520 also includes a configuration utility to discover available wireless networks and create and save detailed connectivity profiles for those networks most often accessed.

D-Link, the industry pioneer in wireless networking, introduces another performance breakthrough in wireless connectivity--the D-Link AirPlus Xtreme G series of high-speed devices capable of transfer rates up to 54Mbps.

The D-Link AirPlus Xtreme G DWL-G520 PCI Adapter is a wireless PCI adapter featuring the very latest in advanced wireless silicon chip technology to deliver incredibly fast data transfer in the 2.4 GHz frequency. The DWL-G520 also works with 802.11b standard wireless devices and when used with other D-Link AirPlus Xtreme G products delivers throughput speeds capable of handling heavy data payloads, including real-time MPEG video streaming.

The D-Link AirPlus DWL-G520 also includes a configuration utility to discover available wireless networks and create and save detailed connectivity profiles for those networks most often accessed.

In addition to being the industry?s fastest wireless network solution, it includes management settings and policy-based content filtering for advanced network management. Filters can be set based on MAC address, IP address, URL and/or Domain Name.
The D-Link Xtreme G DWL-G520 with 108 upgrade is ideal for creating a fast and affordable wireless network, delivering the industry?s fastest wireless network performance. D-Link Xtreme G is also the only 802.11g solution with 108Mbps mode that remains fully interoperable and compatible with all 2.4GHz devices, capable of creating one homogenous network environment for the multi-vendor environment.

Packet Bursting: The packet bursting technique puts more data into a single transmission, allowing more raw data to be stuffed into each packet and as a result not only delivers much more data, but also executes this process with less traffic on the network. Packet bursting transforms lengthy binary code into simple equations, resulting in an overall reduction in the number of 1s and 0s being sent over the network. It is also the technique defined as one of the methods for performance improvement in the IEEE 802.11e QOS draft standard.

Fast Frames: The fast frames technique enhances data throughput by increasing the number of bits sent per data frame and accelerating the timing of a data frame with a dynamic transmit optimizations. This technology enhances the Packet Bursting capability synergistically to provide accelerated performance results. The fast frames technique is also based on the 802.11e QOS draft standard.

Hardware Compression and Encryption: Xtreme G uses the Atheros AR5002 chipset which employs special engines to compress and encrypt data. These hardware engines operate in real-time to enhance throughput by implementing standard algorithms and compressing data prior to transmission and after reception.
Multi-Channel Bonding: Multi-Channel Bonding embraces two radio channels simultaneously. It collapses the available channels from 12 to 6 for increased bandwidth on the available channels. Single and double channels are not run at the same time. This technology senses single channel and dual channel frames and negotiates time-based solutions with priority on single channel processing.
Select Mode: Select Mode gives users the option of locking the Xtreme G products into a Static mode (instead of the default Dynamic mode) for even higher performance within a complete D-Link 108Mbps Xtreme G environment.

The DWL-G520 is a powerful 32-bit PCI adapter that installs quickly and easily into desktop PCs and when used with other D-Link AirPlus Xtreme G products automatically connects to the network. Like all D-Link wireless adapters, the DWL-G520 can be used in ad-hoc mode to connect directly with other 2.4 GHz wireless computers for peer-to-peer file sharing or in infrastructure mode to connect with a wireless access point or router for access to the Internet in your office or home network.
