WIFI is getting auto disconnect while working.

Perform the following targeted checks and changes, given that drivers, BIOS, firmware, and Windows are already updated and the adapter has been re‑enabled:

1. Run the built‑in Network troubleshooter
   1. Select Start > Settings > Network & Internet.
   2. Select Status from the left-hand menu.
   3. Scroll down and select Network troubleshooter.
   4. Follow the on‑screen instructions and apply any fixes it suggests.
2. Verify Wi‑Fi is enabled and stable
   1. Select the Network, Sound, or Battery icon on the right side of the taskbar.
   2. Confirm that Wi‑Fi is turned on and that the network shows Connected.
   3. If it shows another status, reconnect to the correct Wi‑Fi network and monitor whether disconnects still occur.
3. Disable power saving on the Wi‑Fi adapter Power saving can cause the adapter to power down and drop connections.
   1. Open Device Manager and expand Network adapters.
   2. Right‑click the Wi‑Fi adapter and select Properties.
   3. Go to the Power Management tab.
   4. Clear Allow the computer to turn off this device to save power.
   5. Select OK and test for a period of time.
4. Check for and apply any remaining Windows Updates
   1. Select Start > Settings > Windows Update > Check for updates.
   2. Install all available updates.
   3. Restart the device after updates complete.
5. Restart and retest After making the above changes, restart the PC (Start > Power > Restart) and monitor whether the Wi‑Fi still disconnects during work.

If disconnects persist, also check whether the same issue occurs on other Wi‑Fi networks or on other devices on the same network to distinguish between a client‑side issue and an access point/router issue.
