    Hi, check the signal strength between router and laptop, reset and update you router, get a more powerful router, if you use a SIM card get the latest card with Wi-Fi protocol 5G or LTE-A, change your internet plan to unlimited access without a data cap, if you have a mobile router move it to another room closer to your laptop, check/change the charger, cable and router battery. Contact the ISP/phone company if there is maintenance going on in your area. 90% of internet interruption is caused by old modems and poor link quality, seldom by Windows networking or the network adapter.

    The Nitro ANV15-51 laptop has the below provided oem WLAN + BT cards fitted by Acer, if the Mediatek MT7921LE wireless network card doesn't work and disconnects like you say, try to update its networking drive to the last MediaTek, Inc. - Net - 3.0.1.1331 driver - Windows 11 Client, version 24H2 and later, Servicing Drivers, Windows 11 Client S, version 24H2 and later, Servicing Drivers on the Windows Update Catalog to its latest driver below.

    If the latest Mediatek driver above still makes your card disconnect, then try to do a Wi-Fi refresh of the latest driver within Device Manager like this:

    WI-FI Driver Refresh >Go to Device Manager > Network adapters > select your Mediatek MT7921LE card > right click the card Properties > Driver > Update Driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer > and then pick the last and most recent dated Wi-Fi driver that is in that list, and reinstall that driver, then reboot the laptop > as afterwards your Wi-Fi should work properly.

    If all the above doesn't work, I would change the WLAN card to the Intel AX203 card as this card has better support and its easier to get the latest drivers from Intel with the Intel Driver and Support Assistant scan software, as it should fix this problem as you might have a Mediatek faulty card. Otherwise if you still experience problems, your M.2 WLAN board slot pins could be damaged and might be causing these problems and needs replacing, so inspect that. Good luck and hope this helps you out.

    Its the driver that I've shown above for the Win-11 version 24H2 NOT the Win-11 version 22H2 as that is obsolete. Go to the Windows Catalog like I've shown above and download the driver version 3.0.1.1331 and install that driver and see if your Mediatek card doesn't disconnect anymore.
