Fix Mobile Hotspot

So I wanted to mirror my Phone screen via miracast on my Windows 10 Laptop. After installing the additional Windows Feature, it didn’t work. So let’s start troubleshooting!

After some Google magic, I assumed that Mobile Hotspot needs to work. But of course it didn’t.

I downloaded the newest Wifi driver from the Intel site, uninstalled the current Windows one and installed the new Intel. Well to be honest I changed between 4 different drivers on my system but the uninstall part seems to be important. Don’t forget to reboot. I don’t know if that is still needed but with an SSD who cares?

Now lets check netsh:

netsh wlan show drivers

The last line looks promising!

Unterstützte drahtlose Anzeige: Ja (Grafiktreiber: Ja, Wi-Fi-Treiber: Ja)

It still didn’t work, so I tried this trick from Andre for Directly:

  1. Press Windows key + X
    Click Device Manager
    Expand Network adapters
    Right click then uninstall all virtual adapters
  2. Open Start then type: regedit
    Right click Regedit then click Run as administrator
    Navigate to the following registry key:
    Delete the following key: HostedNetworkSettings
  3. Restart then try again.

My hotspot worked again! 🙂

After disabling Mobile Hotspot and both phone and notebook on the same network, I could choose my notebook for miracast! I had to activate the PIN setting on the Laptop or id wouldn’t connect.

And now let’s be honest. It worked once, video has low quality. You would only use that for PowerPoint 😉


18.06.2021: Over the time, Microsoft installed a new WiFi driver without Hotspot-Support. So again, download the newest Intel Driver directly:
