How to Setup Terabyte W777mi Adapter and Driver on a PC

The installation of the Terabyte W777mi WiFi adapter and Driver is very simple. If you purchased this device then you’ve got the manual too which basically describes the features and installation process of it. You can follow that to setup it up.

Well, nobody likes to read the whole manual because of too many extra words in the manual. So, here I’m going to simply describe how you can set up it on your PC in a few steps.

Here are the steps to Install the driver and set up the Terabyte W777mi WiFi Adapter:

  1. Get the CD out of the Package and insert it into your computer DVD writer. After that, just open the CD Drive Disk and open the “MTK” folder.
    Terabyte W777mi - Select MTK folder
  2. In the MTK folder, you will find files like – “MT761XU mac”, “MT7601U Linux”, “MT7601U mac”, “MT7610U Linux”, “MT7612U Linux”, “windows”, etc. Select the folder according to the OS of your PC.

  3. Then Double click on the setup file to launch the Installation Wizard. Click Next and then tap on the Install button.
    Driver Installed
  4. After the complete installation just clicks on Finish and move back to the first interface of the disk files. Then select the “Realtek” folder, and then the windows folder.
  5. Double-click on the “Setup.exe” file. Just install it like we installed the adapter driver from the previous folder.
    Realtek installation setup
  6. After completing the installation, click on Finish and restart your computer. After fresh bootup, take out the USB Adapter from the package and insert it into your PC. If you are using a desktop PC then I recommend inserting the USB adapter on the back panel USB Port.
  7. As soon as you insert the USB adapter, the notification of driver installation will start showing up at the right bottom. And then wait for the USB Adapter detection.
    Internet is working through Terabyte W777mi
  8. Now enjoy the high-speed internet on your PC.

Those files are basically the drivers of the USB adapter which are needed to help the PC recognize and access the USB adapter. If the USB did not recognize by your PC, just restart it (with USB inserted).

And then try to connect to some Open WiFis. At first, try connecting to WiFi with NO password because it will be easy to get connected. Once your USB gets connected try to surf the internet with any browser like Google Chrome, Opera Browser, etc. Just search any random terms such as FB or Twitter and check whether web pages are loading or not. If you face any hardware issues, you can contact the Terabyte service center.

  1. Bro I purchased it,
    After putting it to my pc it is running perfectly, it gives me 80+ mbps at starting but after few minutes it goes down, less than 1 mbps.
    Why I am facing this issue, I check it on my laptop too . Both the system(pc and laptop) facing the same issue

    • Hi, Pulkit

      The initial speed that you see isn’t your actual internet speed. The actual speed gets painted after several seconds of continuously consuming the data. Most Internet speed testing tools do that. Also, it might be the limitation of the WiFi adapter in your system. However, in my case with the same adapter and my Airtel Xstream 40Mbps plan, it goes up to 35-38mbps (Download speed). Hope you got the answer.

  2. i think the realtek setup is unnecessary and it is kind of scam. it gives access of pc to this person. also the realtek name is being misused for hacking user computer. file name such as cisco, realtek etc are installed which shows fake website as source in control panel. even after removing this unnecessary file wifi can work with only mediatek software

    • Yes, the Realtek setup is unnecessary but it is not a scam my friend. It is a utility software that provides control to users over their USB WiFi tool. Also, I don’t own Terabyte. If you buy this tool from anywhere, you will get the same software & driver that I have shared here. About cisco & all that, it just modules that help the USB tool works stable. If you have any doubt or question then you can contact the Terabyte Support Team:

  3. Bro my I have installed the driver and it is detected by my PC in control panel but in control pannel says that no drivers installed for this device .I am using Windows 7 pirated.

    • Try to re-install the driver and it will start working. Just take out the adapter and first install the driver. Once installed, insert the adapter. In a few seconds if you see a WiFi icon on your taskbar then it means the driver is installed & everything is working.

    • I have never encountered this error while installing the driver. Nor I have heard this error before. Please restart your PC and try installing it again.

    • Bro,
      The Windows driver runs fine on both 32bit & 64bit operating systems. Please read the manual paper which comes with the Terabyte W777mi product.

        • I would recommend placing the Hotspot device close to your PC or Laptop. It usually happens when the device is placed too far to supply internet data.

          Let me know if it works!

          • no not that issue the device itself is connecting disconnecting like we know we get a notification of a usb device is connected thats the problem

          • I have never encountered such an issue in my WiFi Adapter. You may have got a faulty one. To avoid such issue from happening again, you can try:

            1. Clean the Adapter & reinsert it.
            2. Update all the drivers on your PC.
            3. Check if the USB port is working properly.
            4. Check whether the Hotspot device is properly working.

            Let me know if it helps.

    • Sorry for your lose, click here to download the driver for Windows. I have provided you the direct download link of the driver that I have copied in my computer. Just download from the link and install it on your computer. Enjoy!
