In this post, you will be guided on how you can set up the USB tethering feature on your Windows 10 computer and share your mobile device’s mobile data so other devices can also access the internet. Tethering is usually known as Wi-Fi tethering which allows users to share mobile data to any device with Wi-Fi, laptops included. This is really useful especially when you have no other way to access the internet. For instance, if you are using a desktop computer and there is no way for you to connect to the Ethernet, and you have no Wi-Fi adapter that you can use to connect to a router as well, you can use USB tethering instead to access the internet. It is almost similar to Wi-Fi tethering except that it works over a USB connection instead of a Wi-Fi adapter. USB tethering is almost quite the same as an Ethernet connection except that it’s faster compared to Wi-Fi tethering as well as Bluetooth tethering. Just like Wi-Fi tethering, USB tethering is free unless your network carrier has blocked it. Thus, it’s better if you make that clear with your operator. Once you have that covered,

Follow the instructions provided below to set up USB tethering on your Windows 10 computer.

Step 1: First, connect your mobile device to your Windows 10 computer using a USB cable. Step 2: If it asks you to enable the file transfer feature, just cancel it. A prompt that says, “Tethering or Hotspot active—Tap to setup” should be available as soon as you get connected – tap on it. Note: If there is no prompt, just go to Settings > Network and Internet > Hotspot and Tethering and from there, toggle on the USB tethering option. Step 3: Afterwards, the setup will create a new network adapter in Windows 10 automatically and your computer should now be connected to the internet using USB tethering. Note: You have to make sure that the Wi-Fi connection in your mobile device is turned off and if it is connected to an existing network, the USB tethering will be disabled but if you see its status as enabled, then the USB tethering setup is successfully done. In addition, keep in mind that the location of tethering can be different for every phone, especially on a customized operating system such as RealMe, Redmi, Samsung, and any other mobile device although they are clubbed in the section of Mobile and Data Network. In case you encounter some problems when using USB tethering in your Windows 10 computer, there are troubleshooting tips you should follow. The NDIS-based Internet Sharing Device network adapter is what Windows 10 uses to make USB tethering possible so if it stops working, follow the options provided below.

Option 1 – Perform basic check

The first thing you can do if you encounter problems in USB tethering is to do a basic check like checking if Wi-Fi is enabled automatically as well as check if the USB cable is disconnected or if you’ve turned off USB tethering accidentally.

Option 2 – Try installing or updating the USB RNDIS adapter

RNDIS or Remote Network Driver Interface Specification can also help you resolve any USB tethering problem. If the pre-installed driver does not help you in connecting to the internet, then you can try installing the USB RNDIS driver that is, if it’s not installed yet. If it is already installed, you can try to update it instead.

• Tap the Win + R keys to open Run and type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• Next, expand the Network adapters section and look for the Remote NDIS based Internet Sharing Device. But if you are using a Samsung smartphone, you might see “Samsung” instead of under Network adapters.
• Right-click on it and then select the “Update driver” option.
• Then select the “Browse my computer for driver software” option.
• After that, select the “Let me pick from a list of available drivers on my computer” option.
• Now uncheck the checkbox for “Show compatible hardware”.
• From the given list on your left-hand side, look for Microsoft and then select the Remote NDIS based Internet Sharing Device on your right-hand side.
• Click on Next. A new popup will appear where you have to click on Yes. This will install the driver.
• Now click on the Close button and restart your computer.

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin. However, there are some servers that don’t have an associated MIME type to support MP4 files and so they fail to play these files. In such cases, you will encounter the “Unsupported video type or invalid file path” error, especially when you use the Internet Explorer browser in Windows 10. To fix this problem, you may have to configure the MP4 MIME type in IIS but you might find that IIS is not enabled in Windows 10 which is why you need to turn it on or enable it first.

Step 2 – Configure the MP4 MIME type in IIS:

• Go to Control Panel and from there, access Administrative Tools.
• Next, click “Internet Information Services Manager” from the list of given options.
• Once confirmed, it will open the IIS console where you have to click the name of your IIS Server located on the left panel. This will enable several options in the central details section.
• Now double click on the icon with the label “MIME Types”.
• After that, you should see an “Add” link option on the right panel. Click on the link to open a configuration dialog box.
• Then type “.mp4” in the File Name Extension field and enter “video/mp4” in the textbox of the MIME Type.
• Click the OK button to save the changes made. This should fix the “Unsupported video type or invalid file path” error on your Windows 10 computer.

Step 3 – Reset your browsers:

• You have to change the default printer.
• And troubleshoot the printer.

For more details, follow the instructions below.

Step 1: Connect your printer to the Wi-Fi network. In this step, you need to turn on your printer and look for the option to connect to a Wi-Fi network. Note that the step to connect to the Wi-Fi network depends on what kind of printer you use as well as its OEM since there will be a user interface or a Wi-Fi button that will get the job done for you. Once your printer is connected to the Wi-Fi network, you need to keep it turned on until the setup is completed. Step 2: Next, add a printer or scanner to Windows 10

• Since you’re already connected to the Wi-Fi network, you now have to go to Settings > Devices > Printers & scanners.
• From there, click on the Add a printer or scanner option.
• After that, the scanning process will begin as Windows 10 looks for the printer and once it finds it, it will display the printer in the result.
• Choose the Wi-Fi printer from the results and click on the Add device option. Once you click this option, Windows will install the drivers via Windows 10 update. Note that this process will apply to all the printers – connected, wireless, and so on.

Step 3: You have to install a printer software In this step, you need to use the driver software from the OEM even though the default printer software works since in most cases, the driver software from OEM works better compared to the default ones and offers much better functionality like ink-saving modes, and many more. Step 4: You now have to change the default printer After installing the printer software, you now have to set or change the default printer in your computer. If you have not installed any printer, the default printer in Windows is the one that saves the files. Now since you have already installed your printer, all that’s left for you to do is to change the default printer of Windows 10 to the one you installed earlier. To do that, follow these sub-steps:

• Go to Settings and navigate to Devices > Printers & scanners.
• From there, check the checkbox labeled, “Let Windows manage my default printer” if there are many printers. This will recommend you to use the most used printer. But if you don’t want to switch to the most used printer, then uncheck the checkbox.
• Once done, click on the printer you want to set as the default one and go to Manage, and then click on the Set as default button.

Step 5: If you have any issues with your newly installed printer, then you need to troubleshoot it One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.
