I am changing my network provider from virgin to ZEN who provide a Fritzbox 7530 as router. My existing setup is with virgin, with their supplied router in modem mode and my decp x20 as the router linked to 2 other satellite nodes which works great.

Browsing forums it seem I can't do this with the fritzbox, but there seems to be a work around. I'm not very tech but can usually follow guides etc... so can anyone help with "simpleish" advice what I need to do before I switch 🤯
