4 out of 5 eggsGreat buy, decent life-span.

Pros: Easy install, popped right in, downloaded and installed quick. Almost no issues. Does what it pretty much says.
Great and had no problems with gaming, streaming, etc.

Cons: Connection would be dead dropped if so much as a small tap of anything came in contact with ether antennas.

Been using this for a bit under 6 months. Very disappointed that it just suddenly stop working. Can't hold a connection, connect, or even be read by my PC.

Other Thoughts: No matter how far or close I was to my router, I could never get past 3 (sometimes 4 bars) of strength.

2 out of 5 eggsLinux-friendly, but poor signal strength!

Pros: I purchased this card for use with a Debian 8 / Windows 8.1 Pro dual-boot on my new computer. Easy installation and for the first month or two, other than a few hiccups, it was blazing fast on both operating systems. My computer is a long ways from the router and the antennas were still able to grab a signal.

Cons: After a few short months this card refuses to work reliably in Windows 8.1 Pro. I have 30mbps down but this card is only able to get 1-3 bars, randomly disconnects, and cannot achieve speeds higher than 100kbps -- if that! Impossible to stream video, download small files, or even update software through APT in Linux.

At the same time it failed in Windows 8.1 Pro, it also failed in Debian and now is only functional approximately 10% of the time. I used a Belkin USB wireless adapter and now receive speeds of +/-10-25mbps compared to the TP link speeds of +/-100kbps. It took over a week of troubleshooting to be sure it was my TP-Link card causing the problem. Sadly unreliable card and it takes up the only PCI slot on my M5A99FX Pro motherboard.

Other Thoughts: I was really excited about this network card when I heard it would mesh well with my Linux installation, since it has somewhat limited hardware support. However, the TP-Link card turned out to be so unreliable that my Raspberry Pi can outperform it with a $10 USB adapter. Using the same Pi adapter in my PC increased my WiFi connectivity tenfold when compared to this PCI card. I have heard great things about TP-Link and I'll consider them in the future, but if I purchase from them again, I will make sure to get a much higher end card that supports Windows 8.1 Pro.

For now, I would recommend sticking to an inexpensive USB adapter or just using the much more reliable ethernet connection if you're on Linux. I have to give this card only 2 eggs because it's a hopeful product, but one that cannot deliver.

2 out of 5 eggsyou get exactly what you pay for

Pros: Extremely cheap.

Cons: upon receiving the package and everything seemed in order, the device plugged directly into my main floor without any issues and while Windows 7 attempted to install the device drivers I went ahead and installed the drivers from the CD. almost immediately I noticed there was a 76% signal rating from the utility. I checked another device with a USB dongle for a wireless adapter which receives higher signal quality between roughly 85 and 92%. well my network was seeing and I could connect to it the device had some issues transferring data from the wireless access point. After checking the firewall on the router I determined that the issue might be with the router itself. I swap in a wireless N router and tried to see what the signal boost would offer, however the signal still remained in the low 70's to mid 80s range of the device is less than 50 feet away from where I am. after a few hours the wireless adapter will drop the wireless signal completely and a vendor the device entirely useless and essentially coming down to what you pay for is what you get.

Other Thoughts: this wireless adapter works well however the price range of a fact that is dropped signal considerably and failed to communicate with two individual routers tells me that there is something faulty on this device. I would not recommend it based on the price alone, however I would recommend trying to find some more reliable hardware either a USB dongle over this particular unit or saving money and finding something a bit more expensive but more reliable.

5 out of 5 eggsGreat WiFi Adapter, Cheap Price

Pros: This was bought for a customer who wanted to be able to connect to his neighbor's (he has consent. lol) WiFi and game on it as well. This person had a tight budget so I decided to try this adapter out. So far, my customer and I have been very pleased with the adapter. The desktop is about 30-40 feet away from the router inside the neighbor's house, and router/modem is from an ISP (so nothing fancy).

The customer is able to maintain 3/5 bars which I was, at first, a little worried. We ran some speed tests and were able to maintain 50-60 ms for ping! We played some games and didn't have a problem at all when it came to lag.

It's been about 2 months at this point and it has maintained it's performance so far.

Cons: None so far.

Other Thoughts: As far as driver installation, I let Windows 7 install the necessary drivers and nothing else. We did not download any drivers from TP-Links website; just let Windows control it.

4 out of 5 eggsQuality

Pros: PCI cards fit well in micro-atx mobos and cases as well as mid and full. Dual external omni-directional antennas aren't too long so they conceal easily. Excellent signal strength. I paired these with a TP-Link 750 dual band router and computers up to 20ft away, through several walls, still had a solid 5 bars with 300mbps connection.

Cons: I'm thinking it's a glitch in the software that came on the disc included with the product, but several computers experienced random disconnections, would not automatically reconnect even when set to do so, and would also somehow no longer have the wifi password saved. After switching to windows wifi manager the problem stopped. Still, I'm gonna have to deduct an egg for the annoyance.

Other Thoughts: Overall a high quality product for home or office.

3 out of 5 eggsTechnical Difficulties with Windows 7

Pros: Works good once installed

Cons: Software is not current, had to call tech support several times. Finally got a technician that suggested I download the current driver software.

5 out of 5 eggsDoes work with windows 8

Pros: Disregard the comment under mine. I have had no issues with this card under Windows 8, 7, Vista, or XP. Windows 8 will install a driver for you, and it causes connection issues for me, but that is a Microsoft issue, not TP-Link! Either run the driver program in compatibility mode or install the driver manually and you will be good to go. I use this, and the similar Mini-PCI card TP-Link has in an older laptop with Windows 8.1 and both work perfect. Im no IT pro, but if you install a card and you get lockups after, use a different driver. In this case where Windows 8 installs a driver, USE THE DRIVER THAT CAME WITH THE CARD!!!!

Cons: None.

Other Thoughts: People are quick to give bad reviews the second they run into a problem without doing a little work on their end. Like they expect the company to come out and install the driver on the cd for them...

5 out of 5 eggs

Pros: Good reception, cheap, reliable connection, doesn't use a PCIe slot

Cons: None that I experienced

Other Thoughts: Can't comment on the utility software, I only installed the drivers. I got this because it seemed to have the best rating to price ratio of any PCI card, and I didn't want to use up my only PCIe slot with a wireless card. Installed the drivers first, then put the card in. It has never dropped signal, and it picks up my router with 100% strength, and picks up neighbors' signals much stronger than my laptop with the included antennae.

1 out of 5 eggsNot Compatable With Windows 8

Pros: n/a

Cons: Windows 8 will assign a driver and the card will appear to run correctly. Under windows 8 this network card will lock your system up while streaming video. As a tech you’ll think its heat, memory or a faulty PS, fact is this card is not compatible with windows 8. Tp-link offers other network cards that will run fine under windows 8, look on their site.

Manufacturer Response:
