One of the most common signs of unauthorized access is a significant slowdown in your internet speed. If your connection is consistently slower than usual, it could indicate that others are using your bandwidth without permission. Additionally, unexpected devices may appear in your connected devices list when you log into your router’s admin dashboard, suggesting that someone else has gained access.
Another signal to watch for is unusual activity on your network, such as unexpected uploads or downloads, especially during times when you are not using the internet. If you notice strange activities, particularly high data usage, it’s advisable to investigate further. Regularly checking your router’s settings can help you identify unfamiliar MAC addresses linked to your network.
How can I see a list of devices connected to my Wi-Fi?
To find out what devices are connected to your Wi-Fi network, log into your router’s interface. This typically involves entering the router’s IP address in a web browser, which is commonly either 192.168.1.1 or 192.168.0.1. After entering your router admin credentials, navigate to the section labeled “Connected Devices” or “Device List.” This section will display all devices currently connected to your network, alongside their respective IP and MAC addresses.
Once you have the list, you can compare the devices shown to the devices you own. To further ensure security, note the MAC addresses of the devices you recognize and keep an eye out for any unknown addresses. If you find unfamiliar devices, it may indicate unauthorized access that necessitates further action.
What security measures can I take to secure my Wi-Fi network?
To secure your Wi-Fi network, start by changing the default username and password for your router. Many routers come with default login credentials that are publicly available, making it easy for unauthorized users to gain access.
