pc cards

I bought this card to put in an existing PC, but the PC has PCI version 2.1. I could not get it to work. The computer wouldn't even boot up when the card was in, and I tried this in two very different computers. Same thing happened. Finally, after much online research, I discovered that the computer must support PCI version 2.2 and above. Since I waited to install it, I cannot return it now so I'm stuck with an unusable card.

I ordered the NETGEAR WGT624 Wireless Router, and this card as a PCI connection. However, the card and the router were incompatible, which was an irritating waste of my time. I saved time by going to a brick and mortar store, locating the compatible card, and buying it there. Don't misunderstand me -- it works great now, and I'm very happy with the ease of installation. I just wish someone would have warned me that not all NETGEAR products are compatible with one another, even when they are so close to being identical.
Just for the record, I ordered the WG311 54 Mbps Wireless PCI Adapter, and needed the WG311T 108 Mbps Wireless PCI Adapter.
If someone can explain why I should have known they are incompatible, other than the adapter cannot utilize the full range of the router's capability, I'd appreciate the insight.

After a considerable amount of time, I decided it was time to augment my home network with a wireless system. I decided that there was no other option than to select hardware that supported WPA encryption. The WEP encryption is very weak (I have heard that it can take less than thirty seconds to crack), and the piece of mind is well worth the extra money. The Netgear router and pc card I purchased (WGR614v4 & WG511v2 respectively) have worked flawlessly. The security upgrades to enable WPA were available on the Netgear site were easy to install, and once again - worked flawlessly. My disappointment came when I found that the pci card I purchased at the same time to use on a PC that was too difficult to wire in, was not going to work. The WG311 was supposed to have a firmware upgrade to WPA in the 'February timeframe' according to Netgear. This target has obviously come and gone. I have emailed Netgear several times, but they have not emailed back. In respect to the setup, design, functionality, and ease of use - I am impressed with most of my purchase. The unfortunate thing is that when this company fails, it does so in a big way.
