Summary: Being that the TL-WN881ND is ONLY a 2.4GHz wireless card… the reception in my basement is about what I expected… just so-so. That’s why I eventually switched to a dual band wireless adapter like the TP-LINK TL-WDN4800 (before going wired).
Pros: First impressions (before powering up and setting up):
Cons: Not much of note worth taking an egg over. The antennas are short so you should plan ahead if you plan on having them hidden behind a huge tower opposite the location of your router. I thought it was odd the spanish instructions i got were for the model 781 not the 881
Pros: The TP-LINK TL-WN881ND Wireless N300 PCI Express Adapter has proven to be Very Reliable, I have been using this for weeks now and has never lost connection and has had very consistent speeds. I am currently using the TL-WN881ND in my PC "Win 7 x64" in the bedroom which is about 70' away and through 4 walls and I'm getting about 70% signal strength. What is really tereffic is that I am getting between 40 Mbps and 60 Mbps from my Network Attached Storage Devices and whe...
Cons: As of right now I have had on problems with the TP-LINK TL-WN881ND Wireless N300 PCI Express Adapter, I will update my review if I have any problems, but I really do not see that happening, I have many TP-Link Products and really have had no issues with reliability.
Summary: 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).
Pros: 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.
Cons: 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 ba...
Pros: This card is cheap, small, simple to install and setup. Simply plug the card into the PCI E x1 slot and screw (not included) the back plate (includes low profile bracket) into place. Install the antennas by screwing them on, and face them up.
Cons: While the range is very good, it isn't the best I've seen. This card is installed in a PC in my basement, and my router is on the top floor. Through all of this it is able to pick up a fairly strong (but not perfect) signal through 3 floors! Other cards I've used have been able to get a full signal, but even with this "less then perfect" signal, I don't notice any connection issues or impact on speed.
Summary: I'm amazed at how weak of a signal I am getting from my router which is less than 30 feet away. I have no visible obstructions between the two devices except for my computer case itself. Moving the antennae around helps boost my signal strength from 29% all the way up to 42%.
Pros: Installation was very easy. The supplied CD had all the drivers and was a very painless process.
