Regular Wi-Fi dropouts and severe Wi-Fi slowdowns

Good evening everyone,

I would like to seek the forum's help because I’m having quite a few problems with my Wi-Fi. For some time now, my Wi-Fi disappears completely without any apparent reason. My computer no longer connects, the Wi-Fi icon is no longer visible in the shortcuts, and the driver disappears from the device manager, although it can be seen when displaying hidden devices. Windows then indicates "this device is not connected to the computer."

I’ve tried to understand the causes and see if I could fix it but without success. The only workaround I’ve found is to reset the network, and even then it doesn’t always work on the first try. I’ve changed the Wi-Fi card and the problem persists (new Intel AX210NGW card). Bluetooth works perfectly.

In recent days, I also notice a strong slowdown of my Wi-Fi. I should mention that I observe this on several different networks.

Could someone help me understand what’s going on?

My computer is an Asus VivoBook M7600QE running Windows 11

Thanks in advance for your time.

    Hello,

    Perhaps the driver:

    For this type of card there apparently exists a driver only for Bluetooth, to check perhaps.

    Thank you for your reply.
    My BIOS is up to date.
    Regarding the disappearance and slowdown of Wi‑Fi, it happens on several different networks. I therefore do not think it comes from that side.
    Is there a way to diagnose the fault precisely?

    Hello and thank you for your response,
    I have already updated the driver but it did not improve the situation.
    I should note that this state is not constant. For example, this morning the wifi was working at roughly normal speed while last night I couldn't even play a YouTube video, for example.

      Hi,

      Do you live in the city or in a place somewhat far from the city?

      Because often with a heavy influx of connections around you and even far away it can harm Wi‑Fi performance.

      You should try at the times indicated with Ethernet cable (RJ45) for example to see.

      Nothing to lose by trying another driver.

      It can happen that a new one works worse than the old one. Depending on the type of machine, of wifi card, and Windows version (or others).

      I had this happen in June with an Realtek update pushed by Windows Update. The new driver only worked for a few minutes.

      Re,

      Apparently you’re all good and even the latest driver that you suggested, Kori-Kori whom I greet, isn’t working.

      So what’s wrong with your PC?

    I live in the city, but the problem has been observed at several different times and in the countryside as well. Whether at work or at home, there are other laptops on the same network and everything works normally.
    I also do not have the option to connect an Ethernet cable (RJ45) to my computer.

      Hi again,

      You should ask your operator if they are not doing work on an antenna that isn’t far from your location, because that would impact this slowdown.

      But when SFR carry out an intervention they notify me by email about it and its duration, day, etc... as well.

    Hello,

    Installing a new card and the problem persists, so it’s not the card that’s at fault but it could come from an M.2 port or even the firmware, also from the power management causing these slowdowns.

    Have you performed a BIOS update to see if this Wi‑Fi works properly again?

    Have you tried unplugging your entire Box from all power for at least ten minutes?

    Replug everything afterwards to reset everything.

    Start with checking that first.
