Fixing to head to Mexico in a few weeks and was planning to take a 4321 Cisco router with me to replace the router that’s at the house I have over there. Only problem is they’ve got a weird setup there, and it’s something l’m not familiar with.

The modem they use is a FIBRASTORE RO015FT WiFi fiber onu device, seems like a cheap Chinese multifunction router but it has a coax and fiber connection coming into it…pretty sure I need a module for the coax which I can pickup for cheap but still unsure how that’s even supposed to work. I figured the WAN is coming in on the fiber but maybe I could be wrong? Was wondering any have some advice on what i should do or consider?
