Hello,
No issues so far, and this morning, for no reason, I lost my Wi-Fi connection (it works with an Ethernet cable, but I don't have access to that from my office, which is why I need the Wi-Fi, especially since I have a laptop).
My network card is Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC.
I'm running Windows 10.
My laptop is an Acer.
Can someone please help me?
I will try to upload the screenshots from my device manager and the Windows troubleshooting utility.

    Thank you again for taking the time to respond to me (even if summarizing, and I had already looked it up on Google ????).
    I'm talking about this "attention" triangle:

    If this is the case, then there is a problem. Except that I don't know how to identify it (perhaps when I started to try to solve my problem on my own I made a mistake?). But if this doesn't belong here, let me know. I'm already relieved that I was able to recover my Wi-Fi connection so I can work (and play, I admit).

      Actually, by suggesting the installation of the chipset, I thought it would solve this problem.
      There is a card reader on your PC; does it work properly? It's possible that it may be coming from there!

      Well, while testing my SD card reader and USB ports, I don't see anything unusual... But I’ll eventually find out what’s wrong (not knowing and not understanding really annoys me!) and I’ll come back for help here.
      In any case, thank you again for your help, that's nice.
      Have a good evening.
      (I had already marked the discussion as "resolved" ;-) ).

        Your problem may also be related to the Lan driver, try this one and then restart the PC, Lan_Realtek_10.1.505.2015_W10x64_A.zip.
        At this hour, it's rather good night!
