4. What Security Type Should I Choose When Manually Adding a Network?

The most common and secure options are WPA2-PSK (AES) or WPA-PSK (TKIP). These security protocols provide strong encryption to protect your Wi-Fi network. If you’re unsure, check your router’s configuration to determine the security type being used. WEP is an older and less secure protocol and should be avoided if possible.

5. How Do I Find My Wi-Fi Password on My Router?

Finding your Wi-Fi password requires accessing your router’s configuration page through a web browser.

Find Your Router’s IP Address: Open Command Prompt (type cmd in the search bar) and type ipconfig. Look for the “Default Gateway” – this is usually your router’s IP address.
Access Router Settings: Open a web browser (e.g., Chrome, Firefox) and enter the router’s IP address in the address bar.
Login: You’ll be prompted for a username and password. The default username and password are often printed on a sticker on the router itself. If you’ve changed them, use your custom credentials.
Locate Wireless Settings: Navigate to the wireless settings section (usually labeled “Wireless,” “Wi-Fi,” or “Security”).
Find the Password: The Wi-Fi password will be displayed in the settings, often labeled as “Password,” “Passphrase,” “Network Key,” or “Security Key.” It might be hidden behind asterisks; look for an option to “Show Password” or “Display Password.”

6. Can I Connect to Wi-Fi Without a Password?

Yes, you can connect to an open Wi-Fi network that doesn’t require a password. These are typically found in public places like cafes or libraries. However, be cautious when using open Wi-Fi networks, as they are generally less secure and more vulnerable to eavesdropping. Avoid transmitting sensitive information like passwords or financial details on unsecured networks.

7. My Connection Keeps Dropping. What’s Causing This?

Intermittent Wi-Fi connections can be frustrating.

Wireless Interference: Interference from other electronic devices (microwaves, cordless phones, Bluetooth devices) can weaken your Wi-Fi signal. Try moving away from these devices.
Router Distance: As mentioned before, distance from the router significantly impacts signal strength.
Driver Issues: Outdated or corrupted Wi-Fi drivers can also cause connection instability.
Router Firmware: Ensure your router has the latest firmware. Check your router manufacturer’s website for updates.
