I bought this dongle hoping to fix an ongoing slow connection problem I had with the onboard wireless adapter on a Dell desktop. I inserted the dongle into an available USB port and Win10 recognized it and installed a generic driver that didn't work. I followed the advice of other reviewers and web searched for "CF-812AC driver" (couldn't use the included mini-cd). I downloaded the .zip file, extracted the file and ran the install program. I then disabled the onboard network adapter and rebooted. My PC wouldn't connect to the internet at first but I got a message "available networks", so I just had to select my home network and enter the password, and the device connected immediately! My connect speed doubled and I couldn't be happier!

After I accidentally hit my laptop on the ground, I couldn't connect to the full wifi in my home. Often, I just dropped the wifi in one space. The thing is small, does not take up the position and USES simply, inserts in the usb port, according to the instruction manual operation may. The first time I installed it, I didn't connect it. After uninstalling the previous installation and changing the socket, I connected it again. Like me this kind of problem to go outside to look for someone to repair the computer, the cost of dismantling the machine, the service charge what estimate all have to 100 200, this thing calculate cheap, solved my computer built-in network card to connect to the wifi problem

This tracker got me good. I am absolutely blown away. The heart rate is accurate, it is water proof (dishes were washed with it on), I set a sleep alarm, I changed the brightness level on the screen. AND ITS IN COLOR. I used to have a Fitbit but the band started coming apart, unfortunately it couldn't be fixed. There are so many good things about this tracker, I (attempt) to do yoga and theres a specific tracking option for it.

I’m very pleased with this fitness tracker. I had an Apple Watch for three years but I always want to try out how well a cheaper brand work. This watch monitors my heart rates, steps, workouts, sleep quality and also sends me notifications for incoming text and phone calls. It does more than I need it to. It is impressively well made. Easy pairing with iPhone 7. The battery lasts A LOT LONGER than my Apple Watch. I don’t need to carry my phone with me all the time. It’s light weight, waterproof, and very comfortable to wear. This is a great deal for the price.

My wifi card went out on my laptop a couple of weeks ago. I searched on how to replace and it would have required tearing down the entire computer to get to the backside of the motherboard. I'm pretty competent when it come to computers and I could have done it but then I found this. It works perfectly and is so small that I don't mind it taking up one of the 3 usb ports I have. I might get around to changing the card out one day but for now this is an excellent solution to my problem. Speeds are great and gets close to the advertised speed of what my internet provider gives. One thing is make sure you plug it into a port that's not near a bluetooth device. Just in case there gets interference. It works perfect!

I have 5 of these things on my home network. Need 1 more. Work best with USB 3.0. Comes with install CD. Speeds always come within points of my router speed plan I'm on. Works on WIN 7 64bit and later Windows or MAC's. If you don't have USB 3.0, FebSmart has a card for Pcle plug in. Win 7 needs a driver, but everything up self installs.

Awesome! It works so smoothly on my Windows 10 laptop. I found it can be over 1300mpbs, after comparing a lot, this is the best option for me. When I recieved this, it exceeds my expectation, I plugged this into my laptop USB port and installed it successfully within several minutes just following the clear installation guide. It's small and portable, a very good shopping experience! I'd 100% recommend it to my friends.
