What should I do if my laptop connects to WiFi but has no internet access?
If your laptop connects to WiFi but shows no internet access, the first step is to check if your router is online. You can do this by connecting another device, like a smartphone or tablet, to the same network. If other devices have internet access, the issue might be specific to your laptop. In that case, try releasing and renewing your IP address through Command Prompt. Open Command Prompt and type “ipconfig/release” followed by “ipconfig/renew”.
If the connectivity issue persists, it may be a problem with DNS settings. You can change your DNS to a public server, such as Google DNS (8.8.8.8 and 8.8.4.4). Go to the network settings on your laptop, find your active network connection, select Properties, and under Internet Protocol Version 4 (TCP/IPv4), click on “Use the following DNS server addresses” and enter the new DNS addresses. Save your settings and restart your device to see if this resolves the issue.
When should I consider replacing my router?
Considering a router replacement may be necessary if you’ve tried various troubleshooting steps without success. Signs that could indicate it’s time for a new device include outdated technology; for instance, if your router is several years old, it may not support the latest WiFi standards (like WiFi 6) or may struggle to keep up with increased bandwidth demands from multiple devices. Additionally, persistent connection drops despite proper setup and configuration may suggest hardware failure.
Another critical factor to consider is if your router frequently overheats or shows signs of physical damage. Anomalies, such as slow internet speeds, persistent disconnections, or unstable connections in various locations in your home can suggest that the router is no longer effectively serving its purpose. If you find that you’ve exhausted all other options, then investing in a new router might provide the solution you need for better connectivity.
