I noticed something strange while using screen mirroring from my phone to my TV earlier today. Another TV popped up next to mine, and I thought that you needed to be on the same Wi-Fi network to do that. My neighbors have asked me for my Wi-Fi password in the past, but I've never given it to them. They might be trying other ways to connect. I've changed all my passwords, including a robust new router login, and I've hidden my Wi-Fi IDs, but somehow, there's still one connection through a cable. I even got kicked out of my router interface after someone else logged in. I live in an apartment, so I'm worried that they could have access to my router. What steps can I take?

Start by changing your Wi-Fi password immediately. Make sure to update your router’s admin password too. Given that you've hidden your Wi-Fi ID, double-check that setting as well; it’s essential if you're worried about unauthorized access.
Hiding your SSID doesn’t add much security these days. It’s better to focus on having a strong password. A longer passphrase for your Wi-Fi and changing the SSID will force unauthorized devices to disconnect.
If your device uses Miracast or AirPlay for screen mirroring, it’s possible they can connect without being on the same network. Have you looked into how you know someone logged into your router? Also, what's this one connection you mentioned that’s through cable?
When you say you got kicked out, what exactly happened? Did you try accessing the router while someone else was logged in? It might be that only one connection at a time can access it, which would explain it.
For additional security, consider implementing a stronger pre-shared key (PSK) and changing your SSID. Remember, some mirroring technologies don’t rely solely on the local network; they might use Bluetooth or Wi-Fi Direct, which could expose your devices.
Yeah, I typed in the IP address to access my router, and only one person can be logged in at a time. If someone else tries, it kicks me out.
