Why Does My WiFi Keep Disconnecting?

Check Your Router and Modem

The first step in troubleshooting WiFi disconnections is to examine your router and modem. These devices are the backbone of your network, and any issues with them can cause intermittent connectivity.

Restart Your Router and Modem: Unplug both devices from the power outlet. Wait 30 seconds, then plug the modem back in. After the modem is fully powered on, plug the router back in. This simple reset can often resolve temporary glitches.
Check the Router’s Firmware: Outdated firmware can cause performance issues.

Access your router’s settings page through a web browser (usually by typing an address like 192.168.1.1 or 192.168.0.1).
Log in with your router’s username and password (check the router’s documentation if you don’t know them).
Look for a “Firmware Update” or “Router Update” section and follow the instructions to update the firmware.

Inspect Cables: Ensure all cables connecting your modem, router, and devices are securely plugged in and undamaged. Replace any damaged cables.

Identify Device-Specific Problems

Sometimes, the issue lies with a specific device rather than the entire network. Here’s how to troubleshoot device-related problems:

Update Network Drivers: Outdated network drivers can cause connectivity issues.

On Windows: Open Device Manager, expand “Network adapters,” right-click on your WiFi adapter, and select “Update driver.”
On macOS: Software updates often include driver updates. Check for updates in System Preferences.

Forget and Reconnect to the Network: This can resolve issues with saved network settings.

On Windows: Go to Settings > Network & Internet > WiFi, click “Manage known networks,” select your network, and click “Forget.” Then, reconnect to the network and enter the password.
On macOS: Go to System Preferences > Network > WiFi, click “Advanced,” select your network, and click the “-” button to remove it. Then, reconnect to the network.

Check Power Saving Settings: Power saving settings can sometimes cause WiFi to disconnect to conserve battery.

On Windows: Go to Device Manager, expand “Network adapters,” right-click on your WiFi adapter, select “Properties,” go to the “Power Management” tab, and uncheck “Allow the computer to turn off this device to save power.”
On macOS: Go to System Preferences > Energy Saver and ensure that “Put hard disks to sleep when possible” is unchecked (this indirectly affects WiFi).

Address Wireless Interference

Wireless interference from other devices or physical obstructions can weaken your WiFi signal and cause disconnections.

Change WiFi Channel: Routers broadcast on different channels. If your channel is congested, switching to a less crowded one can improve stability.

Use a WiFi analyzer app (available for smartphones and computers) to identify less congested channels.
Access your router’s settings page and look for a “Wireless Channel” setting to change the channel.

Move Your Router: Position your router in a central, open location, away from walls, metal objects, and other electronic devices that can cause interference.
Minimize Interference from Other Devices: Devices like microwaves, Bluetooth devices, and cordless phones can interfere with WiFi signals. Keep these devices away from your router and devices.

Advanced Troubleshooting

If the above steps haven’t resolved the issue, consider these more advanced troubleshooting options:

Check for Malware: Malware can interfere with network connections. Run a full system scan with a reputable antivirus program.
Reset Your Router to Factory Settings: This should be done as a last resort, as it will erase all your router’s settings. Consult your router’s documentation for instructions on how to perform a factory reset.
Contact Your Internet Service Provider (ISP): If you suspect there might be an issue with your internet connection, contact your ISP for assistance.

Comparison of WiFi Standards

Standard	Max Speed (Theoretical)	Frequency	Range	Interference
802.11b	11 Mbps	2.4 GHz	Moderate	High
802.11g	54 Mbps	2.4 GHz	Moderate	High
802.11n	600 Mbps	2.4/5 GHz	Good	Moderate
802.11ac	3.5 Gbps	5 GHz	Good	Low
802.11ax (WiFi 6)	9.6 Gbps	2.4/5/6 GHz	Excellent	Low

Understanding the different WiFi standards and their characteristics can help you choose the right equipment and optimize your network for performance and stability.

Tips for a Stable WiFi Connection

Regularly restart your router and modem.
Keep your router’s firmware up to date.
Use a strong and unique password for your WiFi network.
Consider upgrading to a newer router if your current one is old or outdated.
Monitor your network usage to identify any unusual activity.
