If you want to free up some PCI slots or if you have the latest motherboards that only have PCI Express slots (and none of the PCI slots), in my opinion, this is an ok wireless card to have. I used this TP-Link Wireless Adapter to replace an existing wireless card to free up one of my PCI slots.

For me, the greatest things about this this TP-Link Wireless Adapter is that it supports 300Mbps, fits into your PCI Express slot and has a small footprint. My wireless router also supports the 300Mbps transfer rate which means better transfer rates.

When I opened the box, I was amazed at how little the chip was. At first, I wasn't sure if it would fit into the PCI Express slot and be able to reach the outside of the computer case, but upon installation, it fit quite well. The card itself is just like any other wireless cards, the quality of the card feel sturdy. The external antennas were detachable, which made installation easier as well. Although it didn't come with an extra screw to screw into the case, I did manage to find older screws and it is standard size which helped make installation easy.

I use a 128 bit WEP key with my router so it supported that as well. The WPS button was an additional plus because I have multiple wireless devices connected to the router so a push of a button to connect my PC with this TP-Link Wireless Card was a breeze.

It also supports "n" speeds. It connected my PC to the wireless router with reasonably fast "n" speeds. Even though I wasn't getting full speeds (read below in the "cons" section), I was still able to stream HD videos and music files throughout my network. The PC was approximately 15 feet away but through a door and a wall.

I had a full computer case so I didn't utilize the low-profile Brackets that were included but it's a nice addition for those who have smaller computer cases.


First con; although they classify this wireless card at 300Mbps, I never really got up to that speed in downloads and uploads. In my tests, I was not able to get a reliable connection even over 100Mbps. It fluctuated between 48Mbps and 72Mbps, nothing more. I usually got a better signal when I opened the door to my office (where the PC was located) but I couldn't tear down the wall. I was able to get 2 bars constant but that was it. The most I ever got was a full 4 bars and that (again) was when the doors were open wide.

Another con I ran into was the driver issue. It's not such a big issue since it did come with its own Driver CD, but at the same time we're getting into Windows 8 now and it would just be easier if we never had to install another driver again...besides I don't keep CD's anymore but now I'm going to have to keep this one since the driver is on there (or transfer the data onto another HDD).

Another issue I ran into was the inconsistencies this TP-Link Wireless Adapter kept having while transferring data across the network.When transferring a large data file or a large video file to one of my other PC's or laptop over the same network, it was sluggish. It was so noticeable compared to my previous wireless card. There were times it even would hang for a couple of seconds and then continued again. I did notice that downloading large files was much faster than uploading large files across the network.

The last issue is the 5Ghz band missing from this TP-Link Wireless Adapter. I was able to connect to the 2.4Ghz band on the router but now that I've had the pleasure of using the 5Ghz band just for this PC with the previous wireless adapters, it's too bad they didn't include the 5Ghz band. This was a deal breaker in my opinion because a lot of other brands carry both the 2.4Ghz and 5 Ghz band.

Other Thoughts:

Again, if you need a cheap WiFi card in a small form factor that fits into your PCI Express 1x slot, this one is fine.It also comes with a low-profile bracket mount for smaller PC cases. Just make sure that the PC you use this card in is not too far away from the wireless router.
I was only 15-20ft away from the router but already ran into some connection issues. So if your PC is further than that, this card will only put u

Manufacturer Response:

Dear customer,
Thank you for reviewing the TL-WN881ND.
We're happy to hear you like this adapter.

For the wireless connection speed, it seems you're using the WEP-128bit security type on your router.
If so, the wireless connection speed will be limited to 54Mbps. This might be the main reason of your low speed issue.
I suggest you change the wireless security type to WPA-PSK/WPA2-PSK to resolve this issue and enjoy the fast wireless connection.

For the driver issue, you may always get our latest driver from our download page.
The TL-WN881ND fully supports Windows8 now.
