As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

As you know, Bluetooth headphones allow users to connect to their mobile devices wirelessly. This allows you to talk on your mobile device or listen to music without having to connect any cords or wires. Additionally, it even allows you to adjust the volume of a left or right speaker. However, Bluetooth headphones in Windows 10 are another story as their scope is limited. For instance, the left and right pieces can’t have different volume levels. But if you still want to change the dual control of the volume of headphones separately in Windows 10. And in this post, you will be guided on how exactly you can do that. In addition, in this post, you will also be guided on what you can do if the Windows Update messed with the Bluetooth volume control and what you can do to disable the absolute volume in Windows 10. In case you don’t know, the Absolute Volume feature is actually incompatible with a number of Bluetooth devices which can result in the inability of the Bluetooth device to adjust its volume. Thus, if you experience this kind of issue, you’ll notice that the volume slider in the taskbar and the device volume control neither have any effect in adjusting the volume. And each time you try to adjust the volume level for one speaker, the volume of another speaker also automatically changes. In such a case, it would be difficult for you to separately change the dual volume control headphones. Worry not for there is an easy registry tweak you can try to make this possible to do. But before you proceed with the instructions provided below, make sure that you create a System Restore first. Once you have that covered, follow the steps below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor. Step_2: Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMControlSet001ControlBluetoothAudioAVRCPCT Step_3: After that, look for the entry named “DisableAbsoluteVolume” which should be located in the right pane. But if you’re unable to find this entry, you can just create it by right-clicking on the CT key and selecting New > DWORD (32-bit) value, and then assign “DisableAbsoluteVolume” as its name. Step_4: Once done, double click on the “DisableAbsoluteVolume” DWORD and set its value from 0 to 1. Step_5: Now exit the Registry Editor and restart your computer. On the other hand, you can also disable or enable the Absolute Volume feature by executing a command in the Command Prompt.

• If you want to disable the Absolute Volume feature, just execute this command: reg add HKLMSYSTEMControlSet001ControlBluetoothAudioAVRCPCT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f
• If you want to enable the Absolute Volume feature, just execute this command: reg add HKLMSYSTEMControlSet001ControlBluetoothAudioAVRCPCT /v DisableAbsoluteVolume /t REG_DWORD /d 0 /f

After you execute the command, just restart your computer.

After your computer restarts.

Once you’re done executing the given instructions above, you have to right-click on the speaker icon located in the system tray and select Open Sound Settings and click on Manage device settings – the same controls will be visible to you like earlier. Now when you change the volume level for one speaker, the other speaker should now remain as it is and won’t change alongside the speaker.

Typical use of file explorer will probably not need any kind of elevated privileges, but from time to time you might encounter some tasks that will require administrator rights in order to perform them.
