A simple first step is to check if other devices, like smartphones or tablets, can connect to the Wi-Fi network.
The most common solution for router problems is to power cycle it. Unplug the router from the power outlet, wait for about 30 seconds, and then plug it back in. Allow the router a few minutes to restart and re-establish the internet connection. If the problem persists, you may need to consult your router’s manual or contact your internet service provider (ISP) for further assistance.
How can a VPN affect my Wi-Fi connection?
A VPN (Virtual Private Network) can sometimes interfere with your Wi-Fi connection, especially if it’s improperly configured or experiencing technical issues. When a VPN is active, all your internet traffic is routed through the VPN server, which can introduce latency and potentially disrupt the connection. Additionally, some VPN settings might conflict with your network settings, preventing you from connecting to Wi-Fi.
To troubleshoot VPN-related Wi-Fi issues, try temporarily disabling your VPN connection and see if your laptop can then connect to Wi-Fi. If the Wi-Fi works after disabling the VPN, the problem is likely with the VPN configuration or the VPN service itself. You may need to adjust the VPN settings, try a different VPN server, or contact the VPN provider for support.
