So we currently have AT&T which sucks!!! Our service is 45 mbps, a family of 4 with multiple devices makes it slow as hell and consistently around 12-15 mbps. I called AT&T they said I have no available upgrades to improve signal. Anyone have another service that provides strong WiFi for a family of 4+? I bought a router which doesn’t do squat as the modem and signal are garbage. Any suggestions are appreciated
