Good if you install driver
Music and Audio will not work unless you install the drivers... without drivers all youtube or music apps will have weak connection

did not link with wireless earbuds
I need wireless earbuds to teach online, so I bought the TP Link for this purpose. While it says that it connects to headsets, it did not connect my voice (only hearing) to my desktop. After searching online, I found I was not the only person with this problem. They should clearly state that this device does NOT connect with earbuds.

Excellent Ethernet adapter but check the speed and duplex settings are correct for max Gbps speeds.
After disabling my onboard WiFi card, I plugged it in to a USB C to USB 3.0 adapter to plug into a USB A port on the front of my desktop PC . Initially, Ethernet connected but then kept dropping connection. After checking the Ethernet properties in the Network section on my PC, I discovered that the TP-Link UE302C was only achieving 100mbps. I checked my CCleaner driver update page and discovered an updated driver and so I downloaded and updated it. The stability issues disappeared, but the speed was still capped at 100mbps. I then after carrying out an internet search, discovered that the Speed & Duplex setting in Advanced settings, was not configured correctly. I set it to 2.5Gbps Full Duplex and Hey Presto! the Ethernet adapter was now operating at full capability. This information will be useful to some, so please be aware. All in all, a well made piece of kit at reasonable cost. Easy to set up when you are aware of the operating settings. The great thing about this UE302C, is that I can swap it between desktop PC, Laptop, iPhone etc.

Je vais d'abord acheter une ugreen avec bluetooth 5.4 avant de me rendre compte que la marque ugreen n'est pas compatible Linux je me suis tourné donc vers TP-LINK et mon dieu qu'elle fonctionne bien pour son prix même pas une seule latence avec 3 appareils bluetooth connecté manette haut-parleur casque audio
