    Hi, here aree are a few things you can try:
    Check Router Settings, Log into your router’s admin panel (usually 192.168.1.1 or 192.168.0.1). Look for WiFi Bandwidth or Channel Width settings. If available, set it to 160MHz for the 5GHz or 6GHz band.

    Update Drivers: Go to Device Manager → Network Adapters → MediaTek WiFi 6 MT7902. Right-click and select Update Driver. Install the latest drivers from MediaTek or Acer Support if available.

    Modify Advanced Adapter Settings: Open Device Manager → Network Adapters → MediaTek WiFi 6 MT7902. Right-click → Properties → Advanced Tab. Look for Channel Width or Wireless Mode and set it to 160MHz (if available).

    Check Router Compatibility Some routers do not support 160MHz on certain bands. Ensure your router is WiFi 6 or WiFi 6E and supports 160MHz bandwidth.

    BIOS or Firmware Update Some laptops require a BIOS update to unlock full WiFi capabilities.
