2 out of 5 eggsPlease don't buy...

Pros: When it works its good (5eggs for that), but not the case. I cannot get more than 30 KBPS on this card nowadays.I run it on Windows 8.1 and have tried to update drivers, but there are none. Been on the website and its no help as well.

Cons: Just laggy and internet is unusable after 3 weeks of using the card.
Please be warned that if you are building your own PC and run windows 8.1, it will not work.

Other Thoughts: Please release some drivers for Windows 8.1....
Been internetless for the past week...
Sucks that I will have to spend more money on a new card, because this one isn't doing what it does.

Bought on March 16,2014, stopped working by April 2, 2014 and here I am a week later angry and upset.

2 out of 5 eggsLow range

Pros: Good price, Easy to install

Cons: Range is too low to work off wireless router, it detects the router but doesn't connect to the internet. My old laptop is able to connect to the wireless router with its out of date wireless card far better than this one.

Other Thoughts: Unless you are right next to your wireless router, find something else

Manufacturer Response:

Hello Customer,

One issue that I may think of is your current card may be conflicting with the Driver or configuration settings of the old card.

If you would like to reach out to our Technical support team then we can try to assist you further.

Another suggestion is to update or reinstall the Driver for this device. You can find the driver on our website at:

The issues that you may be having can definitely be due to other Networing or Technical issues like your ip address or DNS.

2 out of 5 eggsDropped connections after 6 months of use

Pros: When this works, it works well. Fast connection speeds, no lag, and it's up and running in Windows without drivers.

Cons: Doesn't work correctly after 6 months of use.

Other Thoughts: Like a few others have mentioned on here, I started using this card and all was well for around 5 months, until it started to drop connections. Initially, a restart of Windows would fix the issue. After a few weeks of that, I'd have to shut down and restart Windows WLAN service, than finally, nothing seemed to work.

I thought it was a Windows issue, so I reinstalled my entire OS. Upon boot with the new OS installed - same issue. Works for 5-30 minutes than drops the connection resulting in "no connections available" and stays that way until a reboot or dropping WLAN for 2-5 minutes.

I've tried uninstalling and reinstalling drivers, but no luck. About to toss the piece of junk and find another card that works.

Manufacturer Response:

Hello Customer,

Thank you for your review and we are sorry to see that you are having some issues with this device.

We would love to assist you in the configuration of this Adapter.

I am curious if you could provide the Windows OS version that you are using.

This will allow us to further assit you.

You can always contact me directly at for any issues or concerns.

We also have a 2 year RMA manufacture warranty to replace any devices that me be defective.

Best Regards!

1 out of 5 eggsDANGER!!!

Pros: Native to Linux, worked properly under Linux unlike the chaos it causes under Windows 7 Ultimate 64-bit (see below)


BEWARE OF BIZARRE OCCURRENCES like lock-ups, mouse jerkiness, blank screen flashing, and audio stuttering/freezing incidents for 30+ seconds! (Linux is unaffected, only Windows.)

Don't waste money on another video card or upgrade your PSU as would normally come to mind, it won't make a difference - unless you have an old/budget GPU or use integrated video, take out this card as soon as you can!

Other Thoughts: After about a year, the card just randomly stopped working for both OSes anyway. Taking it out solved all the bizarre problems mentioned above.

5 out of 5 eggsSo far so good...

Pros: 1. 3 external, up-gradable antennas
2. pci interface
3. 300 megabit ability plus the other features at a pretty low price
4. installed pretty easy...was up and running again in about 15 or so minutes, see other thoughts

Cons: none really as long as it lasts :P

Other Thoughts: the antennas are fairly weak so long range application or alot of obstacles/ interference is naturally going to cause an issue. compared to my old adapter (netgear wn111 v2 which has lasted a good time with good performance) i get better latency ( now im hitting 50ms consistantly vs my netgear would fluctuate between 45-75ms sometimes upwards of 90 on a bad day). im hitting pretty much my max internet speeds even though im pretty far away (the adapter is showing 85-90% signal speeds fluctuating between 19-39mbit) which i cant exactly gripe about considering im a good 30 feet away at least with 3 or 4 walls in the way. web pages themselves seem to load alot snappier. i took a gamble seeing as this was my first pci adapter (ive usually gone usb) and so far im pleased. i used the drivers and whatnot that came with it, later on i will probably update them and see if i get a change in performance, will update the review accordingly. Overall i would recommend!

*little side note: for some reason the windows wireless manager didnt seem to want to work until i used the TP-Link manager (running XP pro). Not too sure if that was a driver issue or just windows having a wild hair.

5 out of 5 eggsIt works, no glitches

Pros: It works, no glitches. Says that it will work w/ Ubuntu Linux which I have yet to test with but will try that aspect soon.

Cons: I paid $37.99 1 month ago for it but now see it is on sale for $27.99

Other Thoughts: Regrettably I may still end up wiring the PC I bought this for up with CAT5E. I'm not quite satisfied with the performance of wireless, but that is no fault of the card.

1 out of 5 eggsAddendum to previous review

Pros: Everything I said in my previous review...For 8 days.

Cons: Worked like a charm for 8 days, but now it will not hold connections. At first I thought it was my router (a Netgear R6250 from Newegg), or my modem, but everything works fine with my laptop as well as when I use an old Belkin 802.11g USB adapter.

Other Thoughts: I thought TP-Link was a good brand, I guess it's time to find a new one...

Manufacturer Response:

Hello Customer,

Thank you for trying our Wireless Adapter.

One suggestion may be to upgrade the drivers for this device if you haven't already. You can find the driver from our website at:

This can help with some of the stability and speed.

Some other suggestions maybe to change the Wireless encryption. We have seen some instances were certain Operating Systems have an issue with certain encyrptions. It likes like WEP or WPA(TKIP) may be the best bet since you have some 802.11g devices.

If you have any issues or concerns then you can feel free to contact our 24 hour technical support or you may contact me directly at

Best Regards!

5 out of 5 eggsExcellent 802.11n dedicated card

Pros: I was using an 802.11n USB adapter bought here at Newegg a couple of years ago which had to be replaced after it was broken (a careless mistake by me.) Installation is fairly simple, the hardest thing is getting the antennae attached but that depends on your case and how much access you have to the back of it. I am using Windows 7 so it was detected and the driver installed from the CD. I did try the software which comes with it, but I found it unnecessary and removed it a short time later. I get full reception even though the router is not in an ideal location. I also do not notice any extra lag in games compared to if I attach to my router directly via ethernet.

I originally had ordered a Netis card from Newegg, but I had never heard of that brand. This card is pretty much the same price (at the time I typed this review) and I have actually heard of TP-LINK.

Cons: It's not PCIe based (some motherboards lack PCI slots completely, mine only has one,) and it's not 802.11ac, but all the current 802.11ac adapters are USB based and I wanted a dedicated internal card for reception and performance.

Other Thoughts: I bought this card at a site deemed by Newegg to be a major competitor because, at the time, their regular price was significantly cheaper than Newegg, and the Iron Egg Guarantee only gives Newegg store credit and only if they determine it to be valid. I have had a negative experience with it before so I bought it from them. Newegg has since lowered their price to be pretty much the same, but I needed it sooner.

If I had to buy it again, I would, but only if internal wireless 802.11ac cards were not available (which at this time they are not.)

4 out of 5 eggsNot bad under Linux

Pros: works under Linux you might need to load a driver but works well.

Cons: have to load a driver. tops in Linux will give you G speed only.

Other Thoughts: not bad, just wish i could buy hardware that worked for all not just windows.
