Summary: The part arrived earlier than expected and fit properly, but I had to return it. The program that came on the CD would not work with Windows 7 and the correct drivers could not be found on the internet.
Summary: I did not keep this product because I did not check my computer before I ordered this, when it got here I cound not install it im my computer so I had to send it back for a refund. The replacement part that I did order works great.
Summary: PCI wireless adapter, Linksys has gone through several revisions of this card. I'm not sure what to make of this adapter, most of the time it works without flaw but sometimes it is glitchly as it won't connect to some SSIDs, not sure what the issue is but it is a more popular brand/model and...
Summary: Setup was easy and flawless when instructions were followed (run CD, install adapter, reboot and finish setup). The adapter works but is slower than a much cheaper ethernet adapter or even a USB wireless adapter I bought for a cheaper price. For the price, it should be faster or more versatile.
Summary: The drivers Windows installs for this card are a trap. They will cause a -lot- of packets to be dropped. Please ensure that you get the latest drivers from Linksys' site and use those. Other than this, this card works well with Windows 7, Ubuntu, and Fedora.
Summary: I have Win 7 Home Premium 64-bit. It works slowly on there. However, when I tried this card on Ubuntu 11.04 64-bit, my Internet was a lot faster. So, I guess it's because this product cannot support Win 7 fully.
Pros: Works for Windows 7 after update with Windows Update.
Cons: Slow connection and activity, even after update.
Summary: Before you buy this, be warned this card isn't compatible with Win7 64bit out of box, there is no Win7 driver found on Linksys website either! Are you serious? a wireless card made by Linksys has no Win 7 64bit support? what a joke!
Pros: high speed, big antanna and great signal
Cons: No Win7 64-Bit support out of box! need to find a workaround. Just follow Artpav's step below and it will work with Win7 64-Bit.
