Review: Works perfect for my 2.5g ethernet - i'm middle aged, so when i got an offer to upgrade my internet to 2.5g speed, i had no idea i'd need an adapter. thank goodness they make tech like this for people like me, simple plug-and-play devices that require no tech skills or smarts. just MAKE SURE you have a 3.0 USB port. most modern PCs and laptops have them (after 2018-2019ish), but make sure before buying. the port should say 3.0 above or next to it, or you can google your PC model and find out whether you have 3.0 ports. trust me, i experimented plugging this adapter into a regular USB port, and it didn't work--no 2.5g download speed. but i put it in the 3.0 port, and presto, my speed was something like 2.7, even a little faster than advertised. it's a solid little unit, well built, some folks say you need to update its drivers but i didn't have to, it worked right out of the box (whew). it connected right away and i believe it's compatible with all Windows devices that have a 3.0 USB port. whoever dreams up and makes these handy little USB devices for those of us who don't upgrade our hardware every couple of months, i give you my heartfelt middle-aged thanks.
Review: Worked perfect for older PC - We upgraded our internet speed and had the sad surprise that both my WiFi card and Ethernet port from 2011 were capped at 120mbps. Thankfully I read the reviews and made sure I had the 3.0 USB port before purchasing (not to be confused with a standard 2.0). I plugged it in and did need to install the driver from the website for my computer to recognize it was an Ethernet connection. After I installed the driver, I unplugged the adapter and plugged it back in and it connected to the internet using the Ethernet immediately. It seems most people did not need to do this step from the reviews I read. If you have the 3.0 usb port, this is a great and easy option for an older desktop PC to get the most out of the internet speed you’re paying for without needing to upgrade any internal ports.

### ⭐⭐⭐⭐⭐ Worked properly right away in Win 11 with the Microsoft driver.
*by C***. on June 6, 2026*

It was plug and play with my Win 11 running on Dell 3050sff usb A port. Tested speed with iperf3 from my cpu to Synology DS218 NAS which I installed this same adapter and got transfer rate of 2.76 GBytes. Had to install a driver onto Nas for adapter to be recognized on usb 3.0 type A port.
