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!

Hello,
What is the equipment identification number related to the alert line?
It's HERE to find this information.
Furthermore, which Acer model is involved?
Windows 10 32 or 64 bits?
The number to find might look like this:
PCI\VEN_168C&DEV_002B&SUBSYS_666111AD&REV_01
This driver may possibly work, but I have some doubts, RTLWlanE_WindowsDriver_2023.56.0502.2017.L.zip.
Best regards.

Hello,

So the identification numbers are:
PCI\VEN_10EC&DEV_B723&SUBSYS_B7341025&REV_00
PCI\VEN_10EC&DEV_B723&SUBSYS_B7341025
PCI\VEN_10EC&DEV_B723&CC_028000
PCI\VEN_10EC&DEV_B723&CC_0280

Windows 10 64 bits

My PC is an ACER ASPIRE E5-771G.

I also see that there is another issue in my device manager, but when I look in "Details" the identification number shows root\NetTap6 (the first image from my previous message).

I'm waiting for you to come back to see if I should try the driver you linked or not.

Otherwise, could a possible solution be to restore the PC to its factory settings? If so, wouldn't that cause issues with Windows (I don't remember which version of Windows was pre-installed when I got the PC, I just remember that there was an upgrade to Windows 10, so I don’t know what that would result in?).

Thank you for your attention.

EDIT: I forgot to mention that when I right-click "Update driver," it says that the driver is up to date.

This driver is offered by the manufacturer's website Acer for this model, Realtek_2023.10.415.2015_W10x64_A.zip.
Beforehand, install this chipset, Chipset_Intel_10.1.1.7_W10x64_A.zip then the previous driver, then restart the PC.

Yay: it's working again!! THANK you very much. :-)

However, I would like to understand (even superficially) what happened, why it works and then suddenly it doesn't work anymore.
And what is a chipset? (Okay, fine, I’ll look it up on a search engine… ;-) )

Otherwise, do you have any idea about this unknown device that seems to have an issue as well? It wasn't the case before and it's bothering me.
(I wanted to attach the image, but I no longer have that option while writing this message?! In any case, it's the one with the little yellow triangle "attention" in the first image of my first message.)

No problem, I'm happy for you!
Computing sometimes has its surprises that aren't always explainable; as for the chipset, to summarize, it connects the processor, peripherals, memory—basically all the components of the PC's motherboard, which is why it's often recommended to update it before addressing other problematic drivers.
I'm just brushing over it; we won't go into details here!
