what's happening ? are you getting an error ?

Is the device connected via LAN and the address 192.168.1.2?
with the user name: admin and the PW: 1234

The best thing to do is to configure the device on a laptop that you enter a fixed address 192.168.1.10 so that you are in the same area and then you can access it to configure it

Thank you for the answer. The Internet page does not open. The unit is connected via LAN but has a different address: 5.145.64.124. So I would have to change it to 192.168.1.10 (DHP manually)?
