You can uninstall current wireless network drivers and then re-install them. That should reset all wireless network settings.
To do that, follow these instructions:
1. Right-click the Computer icon and select Manage
2. Click on the Device Manager located on the left pane. There expand the Network adapters and locate wireless network adapter - it should say Intel WLAN or Qualcomm Atheros or Ralink or Realtek, or anything with the words "wireless", "wifi" or "wlan". If you see "Gigabit Network Connection" next to Intel, it represents the wired network adapter (LAN
) so don't make changes to this one
Once you have located your wireless network adapter, right-click its name and select Uninstall. Check the "Delete the driver software for this device" check-box if it is available
3. Confirm by clicking OK and once you see it has disappeared from the list, restart your computer
4. When your computer restarts, it will automatically re-detect the wireless network adapter and re-install the drivers
5. After that, check if the wireless network is working
Let me know the results.
