Why do I need to delete networks from my Wi-Fi?

Deleting networks from your Wi-Fi is an essential step in maintaining your device’s performance and security. When you connect to a new network, your device stores a list of all the networks it has connected to in the past. Over time, this list can become cluttered with networks that are no longer needed or are potentially harmful. By deleting these networks, you can improve your device’s performance, reduce the risk of security breaches, and free up storage space.

Additionally, deleting networks can also help you avoid automatically connecting to networks that may have weak security or are no longer trusted. This is especially important if you’ve connected to public Wi-Fi networks in the past. By removing these networks, you can reduce the risk of your device automatically connecting to an unsecured network, which can put your personal data at risk.

How do I delete networks from my Android device?

Will deleting networks affect my device’s performance?

Deleting networks from your device can potentially improve its performance. When your device stores a large list of networks, it can slow down your Wi-Fi connectivity and reduce your device’s overall performance. By deleting networks that are no longer needed, you can free up storage space and improve your device’s ability to connect to Wi-Fi networks quickly and efficiently.

Additionally, deleting networks can also reduce the risk of security breaches. When you connect to a new network, your device may automatically connect to networks that are no longer trusted or have weak security. By deleting these networks, you can reduce the risk of your device being compromised by malicious actors.

Will deleting networks delete my Wi-Fi passwords?

When you delete a network from your device, it will also delete any associated passwords or login information. So, if you delete a network, you’ll need to re-enter the password or login information the next time you connect to it. However, if you’ve saved your Wi-Fi passwords to a password manager or cloud service, they will still be available even after you delete the network from your device.

To avoid losing your Wi-Fi passwords, make sure you have them written down or stored securely before deleting the network from your device. This will ensure that you can easily retrieve them when you need to connect to the network again in the future.
