Re hello! Sorry for the delayed response, but my problem actually comes from the fact that I have already done that. In other words, I have already gone to "settings > network and internet > etc..." but every time I try to enable sharing on this computer, it tells me it can't configure the hotspot even though I am connected to my Wi-Fi. So my problem is that I cannot share Wi-Fi with my computer even though there should be no issues since my PC is well connected.
If you know how to fix this, that would be great :) Thanks in advance!
In the case of a mobile hotspot, you use a phone connected to 3G/4G, which you activate as a hotspot, in order to connect (for example) a PC to it via Wi-Fi.
If you want to share a PC that is already connected to something, the process is the same:
Select the Start button, then select Settings > Network & Internet > Mobile hotspot.
For Share my Internet connection from, choose the Internet connection you want to share.
Select Edit > enter a new network name and password > Save.
Turn on Share my Internet connection with other devices.
To connect on the other device, go to the Wi-Fi settings on that device, look for your network name, select it, enter the password, and connect.
But of course, if the PC isn't connected to anything, it will be impossible to enable sharing.
