Answer 1

Hi I'm Jan. If none of the suggestions works here are other things you can try.

1. . Try rolling back the network drivers. Press Windows Key + X. Select Device Manager. Expand Network Adapters . Select Wireless Lan Network Properties. Under the Driver tab, try rolling back the driver.   If the rollback option is grayed out, uninstall the driver and restart your computer.
2. Reinstall the Wifi drivers. Download the older version of the drivers directly from your manufacturer's support website. Install the driver and restart your computer. Do not use any third-party driver downloader software to update the driver.
3. Change the Wireless adapter power management settings.

Open the Device Manager

Expand Network Adapters .

Select Wireless Lan Network Properties.

Under the Power Management tab

Uncheck the box for "Allow the computer to turn off this device to save power" then click OK

1. Try to reinstall and update the laptop chipset drivers. Download the latest version of the drivers directly from your manufacturer's support website.

Answer 2

The issue is most likely with the specific laptop, not the router or internet connection, since other devices (including the second Vaio) work fine on the same Wi‑Fi.

Try these steps on the problematic laptop:

1. Check basic Wi‑Fi status and Airplane mode
   1. Select the Network, Sound, or Battery icons on the right side of the taskbar.
   2. Confirm that Wi‑Fi is turned on and that the network shows Connected.
   3. Go to Settings > Network & internet > Airplane mode and make sure Airplane mode is Off.
2. Forget and reconnect to the Wi‑Fi network
   1. Open Settings.
   2. Go to Network & internet > Wi‑Fi > Manage known networks.
   3. Select the home Wi‑Fi network and choose Forget.
   4. Reconnect by selecting the same network from the Wi‑Fi list and entering the password.
3. Restart modem/router and test again Even though other devices work, a fresh connection can help:
   1. Unplug the router’s power.
   2. Unplug the modem’s power (and remove its battery if it has one).
   3. Wait at least 30 seconds.
   4. Plug the modem back in and wait for its lights to stabilize.
   5. Plug the router back in and wait a few minutes.
   6. Reconnect the problematic laptop and see if the dropouts continue.
4. Run the Network troubleshooter
   1. Select Start > Settings > Network & Internet.
   2. Select Status (if available), then choose Network troubleshooter.
   3. Follow the on‑screen instructions and apply any fixes it suggests.
5. Run network reset commands This can fix intermittent issues caused by TCP/IP or DNS problems.
   1. Select Search on the taskbar, type command prompt.
   2. Right‑click Command Prompt and select Run as administrator > Yes.
   3. Run these commands in order, pressing Enter after each:
      • netsh winsock reset
      • netsh int ip reset
      • ipconfig /release
      • ipconfig /renew
      • ipconfig /flushdns
   4. Restart the laptop and test the Wi‑Fi.
6. Check Wi‑Fi adapter and bands
   1. Open Settings > Network & internet and ensure Wi‑Fi is enabled.
   2. If the router broadcasts both 2.4 GHz and 5 GHz networks, try connecting this laptop to the other band (for example, if it’s on 5 GHz, try the 2.4 GHz network) and see if the dropouts stop.
7. Compare with another device on the same network When the problem laptop drops connection, immediately check another device on the same Wi‑Fi. If the other device stays connected, the problem is almost certainly with the laptop’s Wi‑Fi adapter, drivers, or configuration.

If, after these steps, only this one laptop continues to drop Wi‑Fi while all other devices remain stable, the likely causes are:

• Faulty or aging Wi‑Fi adapter in that laptop.
• Driver or OS corruption specific to that device.

In that case, consider updating or reinstalling the Wi‑Fi driver from the laptop manufacturer and, if issues persist, having the hardware checked.
