I have tried twice with two cards, both WMP54g, and neither have worked.  I am using Win XP Pro.  The OS automatically starts the wizard to install the device after boot up.  Then it goes through some questions and finishes by saying that the hardware could not be installed properly.  Has anyone elese had a problem with this on an XP machine.  I have tried the drivers off the Lynksys website.  Did not work.

Don't let XP choose the driver.
Select "have disk" and browse to the driver you downloaded from Linksys.
YOu may also have to disable Byte Merge in your BIOS PCI setup.

You should find ByteMerge as a setting in your BIOS PCI configuration pages.

Chipsets have an integrated write buffer which allows the CPU to immediately write up to four words of PCI writes to it,  freeing it quickly and allowing it to work on other tasks.

The CPU doesn't always write 32-bit data to the PCI bus. 8-bit and 16-bit writes can also take place. But while the CPU may write 8-bits of data to the PCI bus, it is considered as a single PCI transaction, equivalent to a 16-bit or 32-bit write. This reduces the effective PCI bandwidth, especially if there are many 8-bit or 16-bit CPU-to-PCI writes.

To solve this problem, the write buffer can be programmed to accumulate and merge 8-bit and 16-bit writes into 32-bit writes. The buffer then writes the merged data to the PCI bus. Merging the smaller 8-bit or 16-bit writes into a few large 32-bit writes reduces the number of PCI transactions required. This increases the efficiency of the PCI bus and improves its bandwidth.

You may have to disable the feature to get your card to work though, this card and some 3COM cards are know to have a problem with this setting.

I'd first try freeing up an interrupt by disabling unused com and lpt ports and "reset configuration data" in the bios.

tried the Bios change and it did not work.  I started the windows zero config and I got the drivers to install but now can not get the card to recognize the network.  I have a laptop with a linksys wireless card and it read the router just fine.  not sure what to do???

That's progress!

To associate with an Access Point you need to know the WEP encryption settings (if there are any), and the SSID (if there are other available AP's close to you).

WEP encryption is sort of a password, a string or strings of characters used to encrypt the wireless transmissions.
An SSID identifies your station, the default depends on the AP, ANY will scan through the AP's in earshot and try to associate.

Right click on the card's icon in the  taskbar and select netowrk properties, then select the card, right click on it and select the 'wireless networks" - if your access point is listed there, you may have to click on "associate even though I forgot to set up any kind of securit":...well that's not the actual text...

Is it device manager? Is there a yellow exclamation mark?

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

sorry I meant to say that I do not see the name of the wireless network, the SSID, listed in the wireless properties section in the windows configuration screen.  The card is active and working.

New update:

I tried uninstalling/reinstalling in a different PCI slot. I noticed something odd. The light on the card was on until I installed the software, then it went out. Machine said it was installed, it did not recognize and I finally gave up. any thoughts?

At this point I think I'd ask Linksys to replace the card.

That's one element out of the equation.
Can you move the machine closer to test your theory?
You've tried different channels? (1,6,11)?
