Solved Laptop won't connect anymore to a specific network over wi-fi

Hi,
It's the second time that a laptop, an Asus X541U, out of the blue doesn't connect to my wi-fi anymore. It used to connect to it and I could use it no problem for several months, then one day it automatically disconnected and won't let me connect anymore: whenever I try to connect, Windows 10, after "verifying the network's requirements", displays an error stating "Connecting to this network is not possible" (I'm translating so it may not be fully accurate), but it doesn't specify why.
The first time this happened, we reinstalled Windows from scratch and the Wi-Fi worked just fine for around seven months, until now. Both times, we've tried connecting it to an hotspot and that works, that's why I think it's specific to this network (although I have no other means of testing besides hotspot). Connecting it via ethernet to the router works.
I've tried making it forget the password and reinsert it, I've tried changing DNS, switching it to airplane mode for a while, resetting the network configuration (via Windows 10 itself) and tried the Windows 10 tool to solve network problems, I've also just now updated it to Windows 21H2, but nothing works.
Could you give me any advice? If you need any specific info I'd be more than happy to comply; reinstalling windows from scratch might work once again, but doing so everytime this problem arises doesn't sound ideal.
Thanks in advance and sorry for the English, it's not my native language

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Sorry, did reply earlier but it must have been deleted by the issues that we are presently having :(

ASUS Wireless Radio Control Have you reinstalled the drivers for this direct from ASUS.

Driver Booster SkipUAC (Tina) Avoid such garbage like the plague.

Once Windows has been installed, you install the necessary drivers for the MB and other hardware and then leave well alone, drivers should not be allowed to auto update and you should never update any driver/s unless the new drivers are intended to resolve a specific issue that you are having, installing new drivers unnecessarily can actually cause you the very issues that any new drivers are intended to resolve and uninstalling the new drivers may not resolve the problem/s that installing the new drivers has caused.

Depending on priority it can take many months before the driver provider releases any fix and depending on the age of the hardware or software concerned they sometimes do not even bother or may have already announced an end of support.

Thank you for your answer, and no worries, no need to be sorry for the deleted message issue.

I have tried downloading all of its drivers from the asus site (I've downloaded them here), including the wireless radio control one, and I rebooted just as they asked after installation - but no luck: it still won't let me connect to my wi-fi.
In the meantime I've also tried connecting to one of those public wi-fi that require you to register in order to use them, and it does connect to them leading to the registration page, but for some reason it still won't let me connect to mine, at all - not even in the "Connected but no internet available" status, it just displays a generic "Connecting to this network is not possible".

Next time I will install Windows, I will do as you suggested - I will install those drivers before connecting the computer to internet and disable windows 10 from auto-updating them. Still, I'd like to re-install Windows only as a last resort, do you think there's anything else I could try?

Thanks for the answer!
1) It's a modem bundled with the ISP's offer and installed by their technicians, on it there's written "Zyxel Home&Life HUB" but maybe this is a more commercial name than anything; by searching on the web I think it's a Zyxel VMG8825-B50B
2) Do you mean powering it off and then on or something more sophisticated? If it's the first, I think I've tried it but it didn't work; I will surely try it again tomorrow morning, just to be sure, and post an update on the matter
3) Yes it does! That's how it's been used in these days as it's needed for some work

I tried that and...it actually worked. I feel so dumb, grateful and sorry for bothering you when it was this simple, and I really thought I had tried that before, I'm sorry about that.

I still wonder why that happened though, and if everytime it happens I'll have to reboot my router (which is not a big deal, of course) or if there is a solution that is permanent.
I'm ignorant on the matter, but I live in a flat in which there are many home wi-fis active, my phone can detect about eight - could that be the source of the problem? I mean: maybe there's interference or something like that, and it could be solved by moving the bandwith on another channel in the router's settings? I don't know if what I said has any sense sorry, but maybe it can be an useful information.

Yeppoon, QLD, Australia.
it could be as simple as all the other wireless networks in the area are set to the default settings and all using channel 4, or 1, or whatever.
so yeah, you could try changing yours to something up in the high end for both the 2.4G and 5G bands.

or it could be that the modem/router needs to be rebooted every month or two.
they aren't perfect, some are better than others, typically the one provided by your Service Provider is adequate but there are better.
with all the traffic flowing through these units, logging MAC address, wifi connections, up/down time etc, I've always felt there is this internal 'bucket' that gets full and a reboot flushes everything out.
but hey, that's just me! :)

I see, thanks! I was weirded out because this was only happening with this one specific laptop, but not with any other wireless device; if there will be a "next time" in which this problem reoccurs, I'll try changing channels to see if that works, but as long as a simple reboot of the router does it I'm pretty happy.

Thank you all once again and sorry if the answer was something so simple; the problem is solved, so the thread can be closed (do I have to click a button to close it or is it something only moderators can do?)
