2. Uninstall or Block Unnecessary Apps

There are several apps and DNS software services that are known to interfere with a flawless internet connectivity. A good example is Bonjour. It is a software fragment that is at times bundled with iTunes or other dedicated music streaming apps. It may look pretty harmless from afar, but it is known to halt or impede easy Wi-Fi integration in most laptop models. At this juncture, it would be helpful to either disable the app in question or simply blocking it from accessing your computer’s Windows firewall.

To do this, head to Control Panel menu and then click to access the Windows Firewall tab. Right-click on this tab to reveal the ‘Allow a Feature or Program’ option. Ensure that you complete the process by removing ‘Bonjour’ service if it is on this list. As usual, you will have to reboot your computer to restore the default settings of the Wi-Fi connectivity that had previously been blocked.

3. Update your Computer’s Network Driver

Old or outdated drivers will sometimes result in network configuration errors especially if you’re always switching from one Wi-Fi band to another one. Updating your laptop’s network adapter typically corrects the anomaly. And to do this, go to the machine’s control panel then proceed to the ‘Device Manager’ option and select ‘ Network Adapter.’ You can then update the driver by choosing one of the available options under the subset. Reset the newly updated adapter as soon as the update is complete, by first disabling it for a few moments and then turning it back ON.

If you’re wondering how you can update your laptop’s network driver with a faulty Wi-Fi connection, then the answer lies in making use of the laptop’s ethernet connection port. If you’re not sure whether your network driver is up-to-date, then simply uninstall it and re-install it back. After this, you should consider restarting the router and rebooting the PC before attempting to connect to the Wi-Fi, just to make sure the changes applied during the update have taken root in the system’s underlying software. Note that you may be required to re-enter the Wi-Fi’s password while renewing the connection.

And for you to do this, open up your laptop’s command prompt from a login ID with an administrator access. You can get here by searching for ‘cmd’ on your laptop’s start menu.

After this, type in the following acronym ‘ NESTSH WINSOCK RESET’ and press the ‘Enter’ key. As soon as this is done, restart the PC and attempt to establish reconnection to the nearest strongest Wi-Fi network.
