USB WiFi Bluetooth Adapter, 600Mbps Dual Band 2.4/5Ghz Wireless Network External Receiver, Mini WiFi Dongle for PC/Laptop/Desktop

It works very well , however it says this product is driverless, it does have drivers . Overall it is a good product .

I had a customer with an older laptop that had lived a really hard life with drops or falls, but it still worked good enough despite looking war-torn. Until it broke the antenna wire thru the hinge and would no longer connect. She still didn't want to replace the computer. So we put this WiFi adapter on thru USB to restore connections for internet and found the computer worked even better than the original internal WiFi card for speed and reliable connecting. A true way to possibly improve your speed by 2.4 or 5.0 connecting or even turn an older computer into one capable of WiFi connections. Works great!

I bought this adapter so I can get 5g wifi and bluetooth on an older laptop I keep as a spare. Everything is working fine now.........but!!! There were absolutely NO instructions included, only a small thick paper cover folded to hold the tiny installation CD for Bluetooth on Windows that had Wifi specs on 1 section, Bluetooth specs on another section, and the adapter description cover on the 3rd section. getting WiFi set up was arduous and time-consuming. Bluetooth was easy to install since all I had to do was click on the .EXE program file to run & install. Getting WiFi working was a total pain since it isn't an "intuitive" app that guides you through setup. I'm very happy with the WiFi and Bluetooth results, just frustrated that it's not really user-friendly to install. I imagine Amazon Support has received a lot of requests for help.

{Using Windows 10 for this review. Don't let this review scare you with all the details.}Pros: Truly affordable, near-instant install, stable and reliable connection(s), sufficient speeds, online in less than two minutes, WiFi/Bluetooth combo, definitely discrete, and perfect for desktop PCs.Cons: I did have to dig around and poke at settings. By default, the adapter operates on 2.4GHz, and not 5GHz.[Check Your Install]The drivers are on the adapter and installs in seconds (When plugging in for the first time, it will appear as a storage drive. Double-click the newly appeared drive to start the seconds-long install. The drive will disappear and your Wi-Fi/Bluetooth will be active, no restart needed.). The mini-CD is a backup just in case.You may need to double-check Bluetooth settings, and test peripherals to ensure operation (like an XBOX controller). Remove/add Bluetooth devices if necessary.[2.4GHz or 5GHz?]By default, 2.4GHz may be active. You can check by going to your "Wi-Fi Settings". Click on your connected network and scroll down. Look for "Network Band" to check the frequency. If it's not 5GHz, keep reading.To switch to 5GHz, go to Device Manager > Network Adapters > mine reads "Realtek 8821CU Wireless LAN 802.11ac USB NIC" > (right-click) Properties > Advanced Tab > Wireless Mode > Switch the Value to "IEEE 802.11ac" > OK. Give it several seconds and check the Wi-Fi Settings like before. This time, it should read 5GHz for the Network Band![Speedtest.net Sample Results]On 2.4GHz, I had 4ms ping, 36.15Mbps download, 47.23Mbps upload. Best I could get after multiple tests.On 5GHz, I ran one test. Ping is 5ms, Download is 134.56Mbps, and Upload is 53.22Mbps. MUCH better.In short, buy it. It's the BEST value you'll ever get for a Wifi/Bluetooth combo USB adapter/dongle. For over 95% of people, this is all you need.Use 2.4GHz for everyday usage. Use 5GHz for gaming or 4K video streaming.

I recently bought this and have literally spent countless hours and days trying to get this to work right. As a result, I missed the 30-day return date. (I hope this has taught me a lesson.) My final effort was yesterday evening when I said "That's it. I give up! Time for a new computer." First I want to say that the NIC usb adapter did NOT come with a mini-cd as advertised. Nor did it show up on my "This PC" when first inserted as stated is the instructions. I literally read all I could online about this little bugger. And spent countless hours trying this, that, and other things. When you go to Device Manager and click on the properties for this Realtek NIC card, you'll see that the device wasn't started because it requires further installation. Repeatedly. Even though there is no ? on it in Device Manager and it says that it is working properly. But go to the Events tab and you'll see differently. Just writing this review has caused my blood pressure to rise. I feel like I'm ready to blow a gasket. So, yeah, I'm pissed that I wasted my money and TIME on this. So uncheck the boxes for quality, build quality, signal strength, ease of use, etc. This little bugger is a POS.

bought this as a cheap way to add wifi to an older gaming desktop. it does work, and instillation is as simple as plugging it into a usb port, and letting it do its thing. the only complaint i have is the range of the wifi is EXTREMELY limited, and it does not work well through walls, even thin ones in an old house built in the '40s. bars were only about half full approximately 30-40 foot away in the other room, and speed was not great either. i ended up going with a pcie wireless card that only cost a few dollars more, and the signal strength is much better, but this will work if you do not have the slots for a dedicated card, i would just try to set it up in the same room, as close to the router as you can, and if you have the pcie slot for a dedicated wifi card, and the knowhow to install one, just spend the $20-$25 and have a MUCH better experience.

Worked Great!
