Plug and play
Adds wifi and bluetooth to devices that don't have it from the factory. Seems to work just fine. I did end up having to use a wired internet connection on my garage pc I use for indoor cycling, which I suspect was due to conflicting signals.

Simple and works straight away
Simple and works straight away This Bluetooth adapter worked really well for me with no fuss at all. I plugged it in and it worked straight out of the box, with no drivers needed and no messing around with settings. I’ve had no issues connecting any devices so far and everything has stayed stable once paired. It’s small, discreet, and does exactly what it’s meant to do, which is all you really want from something like this.

Brillaint, works as intended
Why did you choose this product over others?: I trust TP Link as a brand for their reliabilty and functionality. As the intended use was for a laptop, the nano sizing was descrete enough to leave plugged in the laptop without looking out of place and without being too big that it didn't get knocked and broken. Ease of installation: Simply plug in and download driver. Was simple and only took a few minutes to install. Speed: The network speed of the laptop was rubbish being an older style laptop now with this plugged in getting download speeds around the 400mbps with 150mbps upload.

Good enough
I bought one of these for my neighbors PC that needed a Wi-Fi add-in card/dongle. It's not the best dongle but it works as expected however I would make sure it is plugged into a port that isn't blocked by walls or other hardware as the signal strength of this isn't superb but it's not awful

Drivers for Win 11 worked fine but on a Win 7 PC had real problems. pls read
I live in the UK, our old copper phonelines are being switched off in 2025 and fibre will be the only option. My main PC (Win 11) and back up PC (Win 7) are in a different room to the fibre router. My Win 11 pc has a wifi card so can connect via wifi but the Win 7 machine has no wifi card. I was looking for a quick and cheap solution so tried the AC600 nano. First I installed the drivers on my Win 11 machine and the adapter worked perfectly. Not so with the Win 7 machine, it would not install the drivers as it was saying they were not digitally signed. After hours of trying various solutions from various sites on the web which did not solve the problem I found a quick and easy solution. There is a downloadable tool from the web, it's called SamFw.com FRP tool. I downloaded this, installed it then clicked on the misc tab and there there is an option to disable driver signature enforcement. Click this then reboot your PC and the drivers will install. If you click the other option enable driver signature then the TP link drivers will not load so don't do that. Hope this helps. After doing the above the adapter works on both machines and receive at only a mgb less than when the PC is wired to the hub.

The device was delivered fast and works well! As soon as I plugged it into my computer, Bluetooth started to work and I even screen recorded my pc window to show this. The product is a bit expensive but you only need to purchase it once so it is a good investment. If you bought this and Bluetooth isn't working, look up solutions online as there are many things that can fix it before returning :)

I was worry since my PC has no optical drive/cd drive since this thing is need to be installed through a mini cd (which is included in the packaged). To my surprised, I just plug it and it works automatically. Bluetooth and wi-fi are working perfectly. Highly recommended to those who wanted to use a Bluetooth operated head phones and speakers. Specially if you don't have or don't like a long cable network passing around your room to your PC, wi-fi ability is great and works well. Thanks to the seller for a "the same day delivery privilege". Kudos!
