Why Won't My PC Running Windows 10 Connect to the Internet?

Internet connectivity is a fundamental requirement for modern computing, enabling access to a myriad of online services, applications, and resources. However, if your Windows 10 PC is struggling to connect to the internet, there are several potential reasons for this issue. This article delves into common causes and solutions to help you resolve the problem effectively.

Common Reasons for No Internet Connection on Windows 10

Physical Obstructions: The WiFi signal can be blocked by concrete or other thick materials. Ensure that your router is placed in a location where it can transmit signals without any obstructions. Ethternet Connection: If an Ethernet cable is used, make sure it is properly connected to both your computer and the router. Outdated Operating System: Running an outdated version of Windows 10 (i.e., versions no longer supported) can lead to security certificate expiration and prevent internet connectivity. Installing the latest updates is essential. Incorrect DNS Settings: Using a wrong DNS server can hinder internet connectivity. Ensure your network settings are correctly configured with the appropriate DNS addresses. DLL Driver Issues: The WLAN AutoConfig service, responsible for detecting and connecting to wireless networks, might be the cause of your problem. This service often needs to be manually restarted or updated. Hardware and Software Compatibility: Desktop computers without a Wi-Fi adapter, or discrepancies in driver installation for laptops, can also prevent users from connecting to Wi-Fi networks. Additionally, there might be a physical switch on the laptop that needs to be turned on.
