Summary: This card works fine to connect my Win7 box to the NetGear WAP I use, but something about it angers other wifi devices in my house. I found that turning off the PC this was in made everything else work better. The included drivers didn't show me an obvious way to crank down the gain on the sending side, so I ended up replacing it with a dinky USB model that did the trick more effectively for my situation. YMMV.
Summary: The TL-WN851ND is easy to install and works properly under Windows XP despite it did not pass the Windows XP Logo Testing according the Microsoft's message displayed during the installation. The throughput is over 100 Mbps from a 30-foot distance, which allows to transfer 13 MB/s (8 b [bit]=1 B [byte]), 800 MB=0.8 GB/min - more than enough for streaming video or file transfers. However, the throughput drops off dramatically with increasing distance.
Summary: Laptop blows it way as far as signal reception in the same room. I have tried updating the driver, uninstalling-re-install and still can't get better than 58-62% signal strength. 2008 HP laptop reception is 99% and download speed at 16 mbps, this card's best is 9 mbps. Same problem this guy is having and I do shut everything off that might interfere with the signal when I test.
Summary: My downloads were lagging on my factory installed card so I decided to try this after buying a router that can handle much more data. I slapped this card into my PCI port (the PCI express port will not work so you may need to remove your modem card from your PCI) and it worked great. I am 4 rooms away from the router and have full bars on this. I'm downloading at a steady 200mbps and reaching speeds up to 300. I'm very happy with how this is performing.

Summary: My son is the computer expert in the family, and said this is easy to install and works as it should. We now have a computer that is now convereted from cable to wireless. It can be used in den near router or a room now up to about 20 feet away. the only negative is we can not get wireless outside about 25 feet, where his brother's wireless laptop will pickup.
Summary: This is a simple A+. It immediately works with Windows 7 and is compatible with all past protocols and encryption schemes. The detachable, fully poseable antennas and narrow circuit-board with two computer coverplates completely cover any conceivable need. All in a reasonably priced package. This doesn't surprise me: I have at least three other different, inexpensive TP Link networking products that all managed to impress me.

Summary: Computer networking upgrades are getting better, and this is an excellent example of how easy it can be. The TP-LINK TL-WN851ND Wireless N300 PCI Adapter, 300Mbps, w/WPS Button, IEEE 802.1b/g/n, Support 64/128 bit WEP, WEP, WPA/WPA2 represents an economical and practical way to when one needs to connect to a network with a good, fast wireless connection.
Summary: For the uninitiated, this product allows your desktop computer to connect to Wi-Fi so you don't have to run a network cable. A perfect application for a PC that's a fair distance from your router. No running of cable through walls, etc. This installed quickly and easily in my Windows Vista (slim case) PC. The instructions were simple and clear. I use this Vista machine in a remote part of the house (about 70 ft from my router) and the signal is rock solid.
