Cheap + works well out of the box

Bought this to use in an HTPC (a low-profile bracket is included, and a doddle to swap in) and found that it worked straight away with Windows 8.1 without even having to install the included software/driver. Doesn't seem to have the best reception strength (same room as my router and not perfect signal) but I get plenty of speed through it and wouldn't hesitate to buy again.



Just got this card with my new rig, really good if you have a router close by, good strong signal with no interfirence, great for the money aswell, i would suggest this to anyone that is looking for a decent wifi card that dosent cost alot and has a good connection signal.

Jobs a goodun

Nice card, I'm ahamed ot say the main reason i purchased this is because I have a zalman Z9 plus and the PCI slot covers are not replaceable and I removed the wron one... So I got this to replace my other one, im planning ot upgrade my modem/router to get the full benefit of it. Also if like me your pc is in a corner moving your pc a few inches out of the corner boosts your signla stength?

Now ot find a PCI sound card to fill the other broken cover...

decent for the price

Since I'm going for an SLI graphics set up, I can't use my old Belkin PCI wireless network card anymore, so I hunted down a cheap PCI-E card that could do 802.11g to replace it, and came to this one.

Set up was easy on Vista; plug in the card, turn the computer on, put in the CD and install the driver. I didn
