1. Some small tips to avoid Wi-Fi mooching
With just a few simple tricks, you can securely protect your Wi-Fi from unauthorized users.

The simplest way to prevent Wi-Fi mooching is to change the default password on your router. First, press the Windows + E key combination, then go to Network, right-click on the router icon, and select View device webpage. Log in with your corresponding account.
Navigate to the Wireless > Wireless Security tab, then enter a new password in the Passphrase (or Key) field and press Save Changes to save the settings. Note that the names of options may vary depending on the type of router.

Changing the default password on your router.
The Security Mode is where you can alter the Wi-Fi encryption mode. If you're using outdated encryption modes like WPA or WEP, it's crucial to switch to WPA2 for enhanced security.
WPS is a technology almost ubiquitous on recently manufactured wireless routers, simplifying the process of device connection to Wi-Fi. Instead of using long and complex passwords, users can utilize a PIN code (an 8-digit sequence) printed on the back of the router for network connection. However, with simple hacking tools, attackers can obtain the PIN from the device and quickly decipher the Wi-Fi password.

Disable WPS mode for enhanced security.
Therefore, it's advisable to disable this technology by logging into the router, navigating to Wireless > Wireless Basic Settings > Wi-Fi Protected Setup, selecting Disabled under the WPS section, and saving the changes. MAC Filtering is a feature that allows you to block or grant Wi-Fi access to any device. It's quite straightforward: first, install the Fing app on your smartphone from the address https://goo.gl/CbUuM to check the entire list of devices connected to Wi-Fi.
When you notice any unfamiliar devices, simply copy their MAC address (a 12-digit sequence), then access the router, go to Wireless > MAC Filtering, tick the Enable box. Add the previously noted MAC address to the list, then choose Allow to permit or Deny to prohibit Wi-Fi access.
Additionally, users can opt for another solution by hiding the Wi-Fi network name to enhance security.
