What should I check first if my computer’s internet is not working?
If your computer isn’t connecting to the internet, start by checking whether your modem and router are powered on and functioning properly. Look for indicator lights on both devices. The lights can provide clues; a green light typically indicates that the connection is active, while a red or amber light may indicate a problem. If the lights are out or not functioning as expected, a power cycle can often help.
To perform a power cycle, unplug both the modem and the router from their power sources. Wait for about 30 seconds, then plug in the modem first and let it fully boot up before connecting the router again. This can refresh the network connection and resolve common connectivity issues.
What if my Wi-Fi network is not appearing on my computer?
If your Wi-Fi network is not visible on your computer, first make sure that Wi-Fi is enabled on your device. Check for a physical switch or function key combination (like Fn + F2) that might toggle the Wi-Fi on or off. Sometimes, the Wi-Fi radio can accidentally be turned off, preventing your computer from detecting available networks.
If Wi-Fi is already enabled, try moving closer to the router. Walls and obstructions can weaken the signal. You can also restart your computer to refresh its network settings. After restarting, check again to see if the Wi-Fi network shows up in the available networks list.
