## Description

Review: 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.
Review: Tiny, but good distance and good for old devices. Works with Ubuntu (Linux). - Very small. Used with Ubuntu 24.04 on a really old laptop to connect to an old Bluetooth creative speaker. It works out of the box and over 20ft away. Ubuntu installed it with no need for user interaction. 5 stars from me

## Questions & Answers

**Q: Does this work with a PS4 controller on pc?**
A: Yes. You need to hold the share and ps button, once it starts blinking it's ready to pair with a PC

**Q: I do not understand, does it act as a receiver or a transmitter when plugged into your PC or both ?, forgive my ignorance but this is all new to me.**
A: It acts as transmitter, so that you can connect devices to your PC such as phones and other devices

**Q: Will it work in a tv soundbar ?**
A: It's likely this would work. I use my soundbar for listening to my phone AND my PC. If your phone can connect to your sound bar via Bluetooth, it's likely your PC would too :)

**Q: My pc  is connected to my phone but my phone isnt connected to my pc?**
A: On Windows, the phone will not connect to the pc unless needed, it is only paired. For example, when you send a file you select the Bluetooth device then it will send it.

### ⭐⭐⭐⭐ This works well, but beware as I found that my Win 10 (Ver 1909) has gap in Bluetooth support
*by R***E on 25 April 2020*

There is nothing wrong with the product itself, and it ought to work well in plug and play with native drivers IF windows 10 Bluetooth support didn't let it down. That's apparently no fault of this product, though, so I haven't marked it down, and there is a workaround. 1) WHAT HAPPENED TO ME USING WIN10 PLUG AND PLAY: Product installs immediately. All drivers present and correct. Paired an audio speaker successfully. But wouldn't play, and in sound control panel it persistently said the device was 'disconnected'. The internet is absolutely full of people reporting exactly the same problem, and loads of suggested "solutions" that simply don't work - I tried most if not all of them! After further research - likely cause is that it seems until Win 8 Microsoft left it to hardware device suppliers to provide their own Bluetooth stack software, but from 8 onward Microsoft implemented a plug and play driver solution within windows itself. But this is inadequate/incomplete in some respects and they are currently working on completing it - no immediate solution therefore unless manufacturers provide 3rd party drivers. HOW I SOLVED IT EVENTUALLY: TP-Link claim to provide pre-Win8 drivers for the UB4a but the link on their website doesn't lead to drivers! However they often talk about UB400 at the same time, and UB400 does offer a driver in the support page for Win 7 and below. I decided to risk trying it with this product on Win 10. Result: it installed perfectly first time and the product now works with devices exactly as expected. You just have to right click the Bluetooth icon in the notification area to gain access to the Bluetooth functions, as obviously this software predates win10 and is not integrated into the win10 native bluetooth interface. The driver software is badged as "CSR Harmony Wireless Software Stack" and although it is a bit long in the tooth, it is a perfectly acceptable substitute until Microsoft get round to finally fixing their inbuilt bluetooth software stack driver. UPDATE: I need to revise the above having just taken delivery of super Bluetooth Headphones which I've reviewed elsewhere. These DID connect to this product when using Win10 plug and play mode without any additional driver. My previous attempts had been with an older Bluetooth cube speaker. So, as other reviewers have said - you might be lucky with plug and play. Seems this may depend on newness of Bluetooth item to be connected. Or, probably for older Bluetooth items, you may need to resort to the older driver as described above. I guess it is down to Windows not recognising/supporting older products - another example of software-driven product obsolescence keeping landfill busy and manufacturers happy. Well I don't give in that easily! My Bluetooth cube speaker lives to fight another day.
