I have a Telekom Slovakia Magio TV + Internet service at home through VSDL

since the service came with a modem-router that does not support 5g(ZTE Speeddport entry 2i ) I bought the TP-Link  AC1200 Wireless VDSL/ADSL Modem Router Archer VR300

internet/wifi is working fine

but I have a problem getting the TV service to work

can anyone point out the correct configuration on this specifi router?

thank you
