What should I check first if my computer can’t connect to WiFi?
First, ensure that the WiFi is enabled on your computer. Look for a physical switch on your device or a keyboard shortcut (usually involving the Fn key) that toggles the WiFi on and off. If the WiFi is enabled but the computer still cannot connect, check if airplane mode is turned on. Disabling airplane mode will allow your WiFi to function.
Next, confirm that other devices, such as smartphones or tablets, can connect to the same WiFi network. If those devices connect without any problems, the issue is likely with your computer. However, if they also struggle to connect, the problem might be with the router or internet service provider instead.
How can I check my network hardware?
To check your network hardware, start by inspecting your WiFi router and modem. Ensure that all cables are firmly connected, and look for any warning lights; typically, a solid power light and connected status lights indicate everything is functioning well. You can also restart your router by unplugging it for about 30 seconds, then plugging it back in. This can resolve issues caused by temporary glitches.
Additionally, for a more thorough check, use another device to access your router’s admin page. Enter the router’s IP address into a web browser and log in to verify your settings, including the WiFi SSID and password. Sometimes, merely updating the router’s firmware can resolve connectivity issues.
