What is the unknown device on my network?

Ah, I see you've stumbled upon an unfamiliar device connected to your network. It's always wise to be cautious when dealing with such matters, as they could potentially pose a security risk. Now, let's break this down: Firstly, have you recently made any changes to your network, such as adding new devices or inviting guests over who may have connected to your WiFi? If so, that could explain the presence of the unknown device. However, if you're certain that the device isn't yours or that of someone you trust, then it's important to take action. Start by checking the device's name and MAC address to see if they provide any clues. You can also try to identify the device's manufacturer by using a MAC address lookup tool. Once you have some information about the device, you can then decide on the best course of action. If you suspect it to be malicious, you should immediately change your network's password and enable security features like WPA3 or WPA2-PSK with AES encryption. You might also want to consider using a firewall or VPN to add an extra layer of protection. But remember, the most important thing is to stay vigilant and keep your network secure. So, always be mindful of what devices are connected to your network and take steps to protect yourself from potential threats.
