Can I see what devices are connected to my Wi-Fi network?
You can see what devices are connected to your Wi-Fi network by logging into your router’s web interface. The process may vary depending on the type of router you have, but generally, you can do this by typing the router’s IP address into a web browser. The most common IP addresses are 192.168.0.1 or 192.168.1.1. Once you log in, you should be able to see a list of connected devices, including their IP addresses, device names, and the type of device (e.g., laptop, smartphone, etc.).
Alternatively, you can use mobile apps like Fing or Wi-Fi Analyzer to scan your network and see what devices are connected. These apps can provide more detailed information about each device, including its MAC address, IP address, and the type of device. Some routers also have mobile apps that allow you to monitor your network and see what devices are connected.
How can I monitor internet activity on my Wi-Fi network?
There are several ways to monitor internet activity on your Wi-Fi network. One way is to use a network monitoring tool like Wireshark or GlassWire. These tools can capture and analyze network traffic, allowing you to see what devices are communicating with each other and what websites they are visiting. You can also use a router with built-in network monitoring features, such as the Netgear Nighthawk or the Asus RT-AC86U.
Another way to monitor internet activity is to use a parental control software like OpenDNS or Circle. These software programs can block access to certain websites, set time limits on internet usage, and provide detailed reports on internet activity. Some internet service providers (ISPs) also offer network monitoring tools that allow you to see what devices are connected to your network and what they are doing online.
