Common causes include IP address conflicts or outdated network adapters. Fortunately, these issues are usually easy to resolve. In the following sections, we\u2019ll walk you through a step-by-step guide to troubleshoot and fix the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix IPv4 No Internet Access<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Restart the Wi-Fi Router or Modem<\/h3>\n\n\n\n<p>The &#8220;No Internet Access&#8221; error is often linked to the Wi-Fi connection. The first step in troubleshooting is to reboot your Wi-Fi router or modem, allowing it to reassign an IP address to your device. This can renew the IPv4 address and restore your internet access.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Disable IPv6<\/h3>\n\n\n\n<p>If your IPv4 has no internet access but the IPv6 connectivity is ok, it might be due to the <a href=\"https:\/\/lightningxvpn.com\/blog\/en\/ip-address-conflict\/\" target=\"_blank\" rel=\"noopener\" title=\"\">IP address conflict<\/a>. You can try disabling IPv6 to fix the issue.<\/p>\n\n\n\n<ul>\n<li>Press <strong>Win + R <\/strong>to open the Run box, type <strong>Control<\/strong> and press Enter to open Control Panel.<\/li>\n\n\n\n<li>Select \u201cChange adapter settings\u201d from the left side.<\/li>\n\n\n\n<li>Right-click your network connection and select \u201cProperties\u201d.<\/li>\n\n\n\n<li>Uncheck the &#8220;Internet Protocol Version 6 (TCP\/IPv6)&#8221; option.<\/li>\n\n\n\n<li>Click OK to save the change.<\/li>\n<\/ul>\n\n\n\n<p>Now you can check if the IPv4 address can access the internet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use a VPN<\/h3>\n\n\n\n<p>If your PC shows \u201cIPv4 no internet access\u201d, it might be because of geo-restrictions. You can use a VPN to fix the issue.<\/p>\n\n\n\n<ul>\n<li>Choose a reliable VPN (e.g., <a href=\"https:\/\/lightningxvpn.com\/\" target=\"_blank\" rel=\"noopener\" title=\"\">LightningX VPN<\/a>) and download it from the official site.<\/li>\n\n\n\n<li>Open the VPN app and sign up for an account.<\/li>\n\n\n\n<li>Select a server that can help you access the website.<\/li>\n\n\n\n<li>Click the \u201cConnect\u201d button.
