5 out of 5 eggsIt works...

Pros: So far the signal has been consistent; minimum to no buffering when streaming; but then again it also comes down to your router. So far my speed has been at 144, yet again it comes down to router.

Haven't run into any problems, it is also mac compatible and runs right out of the box. If your doing a mac clone build.

Cons: none

1 out of 5 eggsPiece of trash

Pros: None

Cons: The driver is a nightmare running on windows 8.1. There are three drivers listed when trying to update and none of them work (including the ones listed directly on TP-links website). The adapter works fine for a few minutes, then it cuts out and needs to be reset. I cannot even download a 240 mb podcast on fios, because it cuts out that quickly. When it is working, my samsung galaxy and surface 2 outperforms my desktop. Look elsewhere if you want to access the internet.

3 out of 5 eggsPoor range

Pros: Easy enough to install

Cons: Does not keep a consistent connection with a router approximately 25ft away in the same apartment. It isn't a clear shot but I am still not pleased with that performance.

Manufacturer Response:

Hello Customer,

Thank you for checking out our Adapter.

One suggestion if you haven't already done so is to update the Driver of this device.

This driver can be found on our website at:

Also keep in mind that the 5GHz band will not travel as far as the 2.4GHz.

If you are using the 5GHz and there is obstruction like walls or doors, then you may find that this distance is too far.

Please feel free to contact me directly at for any issues or concerns.

Best Regards!

5 out of 5 eggsWorks without a problem.

Pros: 2.4Ghz and 5Ghz
Good security features
Compact size
Effective Antennas
Runs at fast speeds.

Cons: I cannot find any.

Other Thoughts: I have been running my desktop with a powerline for over a year now. The powerline technology gives full speed of a direct connection anywhere in your house, which gives great performance. This card has worked well enough I have decided to use it always instead of my powerline.

The first really good thing I found about this device is that it works on the 5Ghz frequency. There are many electronic devices in the world today like wireless headphone technology that works on a 2.4Ghz frequency. The problem with that is that it can interfere with wireless internet which operates on the same frequency. Combining this wireless card with any 5Ghz wireless router should allow you to avoid interference with any other electronic devices. This has proven very helpful.

After this, there are other aspects of this device that work extremely well. Despite the antennas being only about 2.5 inches long, they work perfectly. I have a lot of difficulty even with my laptop picking up wireless in this room of my house. I used a Rosewell wireless card with much larger antennas and that allowed my desktop to connect but often only had 1 bar of signal strength. This device most of the time works with 3 bars of signal strength, in the same position, with antennas less than half the size.

For the other features of this device, they are pretty ordinary. There is no trouble connecting to a secured network, and speeds seem to be overall good. I was not able to test the transfer speed to its max potential, but it works exactly the same as the wired connection did. It works well enough you cannot notice which means its excellent fast service always. While loading videos I only ever noticed pauses when my brother was playing videos and playing online games at the same time, and it comes as a result of my limited internet package to my Internet Service Provider. Whenever he was not doing this, the device works perfectly without even a pause on high definition video streams.

I highly recommend this device to users because the fact that it does work so easy without any problem. That is the mark of a good network device. That you put it in, and it works without ever needing any maintenance or other interactions. If it occasional quits working then its a bad device, but this one has had no problems since receiving it. It works flawlessly.

I would highly recommend it for anyone. It has everything you need for a fast modern network.

4 out of 5 eggsEasy install and it works

Pros: Easy to install, just insert the card into a PCI-e slot, attach the two industry standard antennas, and Windows 8 does the rest.

I did not install anything from the included mini CD. Windows 8 installed the Driver automatically. I used the Wireless manager built into Windows 8 to manage the Card (e.g. connect to my Router via either the 2.4 or 5.0 GHz wireless network). Just move your mouse to the lower right-hand corner of your screen.

Windows 8 indicated I connected at 300 Mbps on both the 2.4 and 5.0 GHz networks. Signal strength was three of five Bars at ~50 feet through one wall.

Also see my 2/10/2013 review of this product. The card appears to be identical to the one I reviewed earlier.

The Box has been updated to show a Windows 8 Logo and Low Profile Bracket (which is now included unlike the earlier card).

Cons: Download speed is rather poor. This may not be the fault of the card (since it is lower than my earlier test, I am still investigating). My laptop runs ~12 MB/sec for both both upload and download on 2.4 GHz (laptop does not support 5.0 GHz).

I measured the following between the TL-WDN3800 adapter and a TL-WDR3600 router (to/from a Gigabit Wired PC):
- 2.4 GHz: Upload 9.1 MB/sec, Download 2.8 MB/sec
- 5.0 GHz: Upload 13.2 MB/sec, Download 4.1 MB/sec

I saw similar speeds when initiating the Tests from the Wired PC. That is, much lower transfer rate when a file is transferred towards the Wireless PC (vs. away from).

Other Thoughts: Having the option of both 2.4 GHz and 5.0 GHz is desirable in areas with high external air-space interference.

Wireless Standards will likely shift from 802.11 a/b/g/n (a, b and g are already obsolete) to the new 802.11 ac, but this will take some time. Likely your Modem is the bottleneck on your Internet network anyway.

The TL-WDN3800 adapter is the third in a series of four TP-LINK wireless adapters (PCI Express x1) TL-WN781ND (150 Mbps @ 2.4 GHz), TL-WN881ND (300 Mbps @ 2.4 GHz), TL-WDN3800 (300 Mbps @ 2.4 or 5.0 GHz), TL-WDN4800 (450 Mbps @ 2.4 or 5.0 GHz).

4 out of 5 eggsGood card for a great price

Pros: - Compact design
- Antennae’s can be repositioned
- Connected quickly and easily to my router
- Comes with a low profile bracket if needed
- Stable connection for the last week

Cons: - Driver CD does not contain Windows 8 drivers, drivers are dated 6/20/2013 on their site
- Utility? (see below)

Other Thoughts: There was a separate download for the Utility, I figured I would check it out and when I attempted to install I was presented with a Repair screen for the Utility and Drive install. Looking around my PC, I can’t find a TP-Link Utility. Nothing in systray and nothing appearing as part of the adapter. I can’t comment if the utility is useful or not on Windows 8.1.

Speed Tests:
Basic Win8 driver test results on 10ms Ping, 16.60 Mbps Download, 4.50 Mbps Upload
TP-Link Win8 driver test results on 9ms Ping, 28.48 Mbps Download, 5.95 Mbps Upload
Same test location and tests were run a few minutes apart after loading the TP-Link driver. If you are running Windows 8, it is definitely worth visiting their download page and grabbing their Windows 8 drivers.

Transferring a 4.01 GB file, home network is 1 Gbps wired to home server:
WiFi: Server to PC = ~21 minutes, 80 Mbps peak
WiFi: PC to Server = ~20 minutes, 97 Mbps peak

For my test with gaming, I loaded up some Battlefield 4. Tracking ping values was tedious and not helpful. But... I can say that it was playable, but not as good as using my wired connection (obviously). I wouldn’t be opposed to using this for gaming, but since I have the choice I opted not to.

Streaming media (Netflix, Xfinity, YouTube) was fine. The video was smooth and the highest resolution was always available to me.

Closing thoughts: The card works well once the Win8.1 driver is loaded and I would use this in a system in another room, which includes any type of a home theater. Having used this for the last few days, I am happy with it! I had to subtract a star due to the age of the CD that was completely lacking Win8 drivers and the downloadable app that does something I’m still not certain of what that is.

4 out of 5 eggsTP-LINK TL-WDN3800

Pros: There are a lot of wireless cards out there promising various things, and TP-LINK is a brand that usually promises functionality at a competitive cost.
When this card functions, it functions well. The setup and driver install were simple. The card has a standard PCI Express interface, something most home PCs have a spare slot for. this card should do nicely in terms of compatibility. The WI-Fi connectivity is fast and generally stable. There have been a few connection hiccups (TP-Link software related) but nothing I wouldn't expect from a card at this price level. Good signal at 45 feet away from my wireless router going through 2 walls, windows shows 3 to 4 bars for the signal strength.

Cons: Unfortunately, I have no choice but to dock TP-LINK 1 Egg for the software bundled with this card. They push their own wireless interfacing software, going so far as to make it seem like a smart choice to install it. The average user will probably install it along with the driver, because TP-LINK recommends it. -1 Egg for the faulty software,
this software was pushed heavily during the install using the disk provided. It's a misleading promise.

With the software installed, this card connected and disconnected from my wireless network rapidly, completely at random. It made downloading anything nearly impossible.

Other Thoughts: The card itself is fine for its price. That being said, the wireless network manager it comes with is junk, and should certainly be skipped regardless of TP-LINK's personal recommendation. Run it through Windows' default wireless network managing tools, and you'll be fine.

4 out of 5 eggsIt Does It's Job

Pros: - Can be used with a Low Profile computer
- Well written installation guides
- Easy to use software with a good interface

Cons: - Software has issues on my computer
- Card did not fit well in my system

Other Thoughts: Let's start with the good. This card can be used in a low-profile case, and comes with a low-profile bracket. The instructions and guides are well written, easy to follow, and unlike a lot of products I deal with, have good grammar. The software is easy to install, works well, and surprisingly has a decent user interface.

This leads me into the cons. The software has some serious issues with my computer. Even when minimized to the system tray, the program hijacks focus every 2-3 minutes. This prevents the screen-saver from working, and can also be very aggravating while gaming. Closing the software fixes the problem, and I have no problems managing the card from the Windows Network and Sharing Center. The reason I took an Egg off though is because of the fitment inside my case. When properly seated in the PCI slot, the other end of the card and bracket sit about a quarter inch in from where they need to be. Now, this is easily remedied by pushing the bracket into place, but I do wish that the fitment was a little bit better.

In terms of range, it could be better. I get one bar less than full strength about 30 feet from an access point through a couple of thick walls and with a lot of interference. That may sound good, but my other wireless card has full strength under the same conditions.

Overall, this is a solid card that performs as it should. If this card is what you are looking for, I see no reason not to get it.

3 out of 5 eggsFailed in 1/2 a year

Pros: price

Cons: range is limited , speeds are slower then Ethernet buy a lot (2.1 Mbs download on card, 4.7 Mbs on Ethernet while downloading)
the card didn't fit well into the Thor v2, had to bend the bracket.

Manufacturer Response:

Hello Customer,

Thank you for checking out our Adapter.

We are sorry to see that you've had some difficulty with this prodcut.

One suggestion that we have is to upgrade/reinstall the drivers if you haven't done so already.

You can find the drivers on our website at:

One other suggestion may be to upgrade the antennas if you find that the distance is relatively far.

On the Router some settings that we've noticed to improve the speed are setting the Channel width to 20 MHz. This improves speed and stability.

You can also try using the AES encryption for WPA2. This allows the clients to use the full wireless N speed.

Feel free to contact me directly at for any issues or concerns.

Best Regards!
