Product Description
Manufacturer's Description
The TL-WN851N Wireless N PCI Adapter complies with IEEE 802.11n (Draft 2.0), IEEE 802.11g, and IEEE 802.11b standards. Wireless transmission rates can reach up to 300Mbps. The PCI card employs MIMO technology and has two external detachable omni directional antennas providing even better wireless performance, transmission rates, stability and coverage. At the same time, CCA technology automatically avoids channel conflicts using its channel selection feature. This product supports 64/128/152-bit WEP encryptions, as well as WPA/WPA2 and WPA-PSK/WPA2-PSK encryptions and mechanisms in addition to the adapter's QSS (Quick Secure Setup) feature, allowing users to quickly and easily configure wireless security. This product can also simultaneously operate bandwidth intensive applications such as voice and video. Applications using a lot of bandwidth that are sensitive to interruptions such as voice and video applications are given priority in order to assure quality. It also works well with other 11g and 11n protocol wireless products.

5.0 out of 5 stars
Excellent even with windows 7, xp or fedora,

This review is from: TP-Link TL-WN851N Wireless N PCI Adapter (Personal Computers)
I picked up one of these a few months back after my long serving tp-link USB adapter died.First of i installed this on windows XP and it went well although i did use the drivers on the disc once only to connect to internet so i could download the latest ones from TP-link and i had no problems. I then installed windows 7 a few months later and it went 100% better showing me the available networks i could connected to during installation just before i had even loaded into windows 7 for the first time so that was good. I even loaded Fedora linux for a dual boot and it worked straight away even without installing fedora so i can safely say this is the most compatible product i've had yet. As for speed i borrowed a tp-link N router from a friend to do some proper speed tests as i only have a tp-link G router at the moment and it worked super fast. Even using a G router i was impressed because although i was capped by the speed of the router i managed to get a better signal and a more constant signal as well as a higher speed than i had with my wireless G USB adapter. All in all i'd say this a great product considering how cheap it is and since it works out the box with windows 7 and fedora without any installation as well as with XP using the disc you can't get a product that is as compatible as this. Will be buying another for my father which will be replacing his much more expensive and worse performing d-link card.

Works straight out of the box in Windows 7 64-bit,

This review is from: TP-Link TL-WN851N Wireless N PCI Adapter (Personal Computers)
I don't quite know why others have had any problems with this network card. I've purchased two now, one for me and one for my brother. They both work flawlessly - both on Windows 7 64-bit.In fact, they installed using standard Microsoft drivers. Didn't even need to use the CD that came with it. Those people who claim that their data speeds are not what they thought they would be: either your router is capping the speed (if your router is only 54Mbps, then no matter how good the wireless card is, this will bottleneck everything), or there are interference problems. Certainly, irrespective of data speeds, this card has proven to give good range for reception. I can't fault it. [EDIT] I've since discovered that the drivers for the card seem to struggle badly with certain routers. I recently changed routers and even though I was only a few feet from the router, my signal strength reduced from 5 bars down to 3, and I couldn't get any 802.11n speeds out of it. I've no idea why. I've since replaced this card with Edimax EW-7612PIN 300Mbps Wireless PCI-E Adapter and this works _perfectly_.

3.0 out of 5 stars
Not a strong enough signal for me,
This review is from: TP-Link TL-WN851N Wireless N PCI Adapter (Personal Computers)
Despite the hefty-looking aerials at the back of this, the signal strength just wasn't sufficient for me. Admittedly, my router wifi is weak, and the PC I fitted the card to is awkwardly positioned. But even with lots of aerial tweaking I ended up with drop outs, unless I pulled the PC out of the dark corner it's in. I'm getting better results with a USB stick pointing from the front of the PC. So, if it's a signal boost you want, this may not be for you. If you want something less fiddly than USB and always on, go for it.Edit: I gave this to a colleague who has found the signal strength and speeds excellent. It's going to depend on positioning I guess!
