TL-WDN4200:: Works with Windows 8.1 Pro 64-bit after tracking down an updated driver from MediaTek R. DECASTRO September 10, 2014
Like many Windows 8.1 Pro 64-bit users, this dual-band adapter failed to see the 5 GHz band of my router out of the box. Great 2.4 GHz speeds (195 Mbps), but disappointing not to have get the expected 5 GHz speedball. The problem is with the PlugNPlay-installed driver from Microsoft (dated 5/15/2013, v. The adapter can see and connect to the 2.4 GHz band just fine. After a friendly but ultimately unhelpful interaction with TP-Link support, I checked the adapter's chipset (Ralink RT3573) and tracked down a later driver (dated 6/27/2014, v. from MediaTek ( The download installs the driver into Windows. Then you access the Update Driver... button for the TL-WDN4200, pick Browse my computer for driver software, Let me pick from a list of device drivers on my computer, then pick the MediaTek driver. Afterwards, the 5 GHz band should show up. I now joyfully get 405-450 Mbps, as advertised. I dropped my rating one star for the trouble this product caused me.

Good for the price--better because it is small Dusty White February 26, 2013
I know there are almost a hundred reviews already, but I hope you will give me just a minute. By the way, I even uploaded images to help you see more about this product. I testes this head-to-head for an hour straight against a Sinmax 300 mbsEtekcity High Power 802.11 B/N/G 300M USB Wireless 1000mw Wifi Network Adapter with Dual Antenna. Of course the Sinmax gave me 5 bars of reception from my 4620LE Jetpack (cellular modem -- 30 feet away) and this gave me 3, but this is more designed for laptops and portability. The Sinmax (made by Elekticity) is portable, but it has those 6" bunny ears. So, what is the verdict? this old up. It gets better reception than the built-in PCI-express wireless card (that has a 5" antenna I had to screw into the card) that came standard with my i-7 Windows 8 ASUS. So if that card is new and this tiny USB antenna can whomp it, it is not a bad portable antenna.

I remember my old T-Mobile USB antenna "dongle" came with m micro card slot and you would use it as a flash drive. This does not--just so you know. It has one function, and it does it reasonably well. I had bad luck with Windows 8, but it did work once I went into Device Manager (Start: search "Device Manager" and click that, look for Network Adapters, and see the images I uploaded). On a separate machine I tried it (the 3200) on Windows 7 and Windows found it right away--the mini-CD is useless.

The speed is good, and the signal strength is better than adequate, but IMHO, if you need a strong signal and you don't mind bunny ears, get the Sinmax (Elekticity). But if you need a LAPTOP or tablet antenna or antenna booster (if yours is weak) this is a great little product. It looks cool, it is small, and pops right into a USB, USB 2, or USB 3 port. Just to be fair I used a USB 3 port for my tests to max out the data transfer speeds.

I am keeping this thing. It won't be obsolete any time soon and it is small enough, and cheap enough that it can fit anywhere and I am not concerned about losing it. This is the perfect device for travelling. Anyway, thanks for reading--hope this helped.

Not very fast. Mr.Knowall October 21, 2015
Could not achieve higher download speeds.

It's gonna take up a couple of USB ports... DL October 19, 2015
Works well. The only problem one may run in to is that, for PCs, this is a bit large for USB - both in its thickness and width. I can stick it in the front of the PC usb and i don't care, but if you're looking to stick it in the back and out of sight, you're gonna need to sacrifice a couple of ports to make room for this. They do provide a short usb cable so you can attach it easier on a line, but who wants that. Otherwise, can't complain.

Great thru put! Fred September 19, 2015
