No, you do not necessarily have to connect the PC to a WLAN router, there are several options for establishing an Internet connection.

- WLAN connection: If your PC has a Wi-Fi module, you can connect it directly to the Wi-Fi network. This is usually the case with modern PCs, such as the Bandit P20.
- Wired connection: You can also establish a wired connection via an Ethernet port if your PC and router have corresponding Ethernet ports. This often provides a stable and fast connection.

So it depends on your preferences and the available options which method you want to choose.
