Hello. In my home I only have internet mobile by a hotspot ZTE MF920U. Now I want to expand the signal for all house (140m² / 1506ft²) with good quality like an AP Wifi. I think in a tp-link Deco Mesh M4, but in instruction it's refered to connet a ethernet cable to the ISP router. But my ISP router is the ZTE hotspot and it's don't have ethernet connection. It's possible use a Deco M4 like AP with my ZTE hotspot without cable? What your sugestion of tp-link product who help me my need? Thanks.
