How do I get my Wi-Fi network back?

How to Restore Your Wi-Fi Network

Experiencing a sudden loss of Wi-Fi connectivity can disrupt work, entertainment, and other daily activities. Fortunately, there are several troubleshooting steps you can take to restore your Wi-Fi network.

1. Network and Internet Troubleshooter

Windows and Mac operating systems offer built-in troubleshooters that can diagnose and resolve common network issues. To access the troubleshooter:

• Windows: Go to Settings > Network & Internet > Troubleshoot > Network Adapter.
• Mac: Go to System Preferences > Network > Assist me > Diagnose.

2. Verify Internet Connectivity

If your modem is not receiving an internet signal, your Wi-Fi network will not work. Check the following:

• Ensure that the modem is connected to a live telephone line or cable outlet.
• Inspect the modem’s lights for any unusual activity or errors.
• Contact your internet service provider if the issue persists.

3. Delete and Re-establish Wi-Fi Connection

• Windows: Go to Settings > Network & Internet > Wi-Fi > Manage Known Networks > Select your Wi-Fi network > Click “Forget.” Then, reconnect to the network using the password.
• Mac: Go to System Preferences > Network > Wi-Fi > Select your Wi-Fi network > Click the “-” button > Reconnect to the network.

4. Reboot Modem and Wireless Router

• Unplug both the modem and wireless router for 30 seconds.
• Plug the modem back in and wait for it to establish a connection.
• Plug the wireless router back in and wait for it to power on and connect to the modem.

5. Adjust Wi-Fi Channel and Frequency Settings

• Windows: Download NirSoft’s WiFiInfoView tool to analyze Wi-Fi networks in your area. Choose a less crowded channel for your router.
• Mac: Open Terminal and type “sudo iwlist wlp0 scan” (replace wlp0 with your Wi-Fi adapter’s name). Select a channel with the lowest signal level.

6. Try Connecting with a Different Device

If you are still unable to connect to the Wi-Fi network, try using a different device such as a smartphone or tablet. This will help you isolate the issue to your device or the network itself.

If the issue persists after trying these steps, consider the following:

• Reset your wireless router to factory defaults.
• Update the firmware on your modem and wireless router.
• Contact your internet service provider for further assistance.
