If multiple devices are trying to use the same static IP address, it can cause connection problems. Ensure each device on the network has a unique IP address.
Securing Your Network Connection
Security is paramount when dealing with computer networks, especially if you’re using a wireless connection.
1. Change Default Credentials
Many routers come with default usernames and passwords. Change these to prevent unauthorized access.
2. Enable WPA3 Encryption
When setting up a wireless network, always opt for the highest level of encryption, such as WPA3, to secure your data against intrusion.
3. Regularly Update Your Firmware
Firmware updates can fix vulnerabilities and improve performance, so check your router manufacturer’s website regularly for updates.
