I'm currently running at&t's gigabit fiber internet speed. When I'm hard connected to it via Ethernet I get the expect speeds of a gigabyte fiber internet but when other people around my house are connected or when my iPhone is connected its not as good if anything my phone internet speed is faster then the WiFi. I currently have the basic at&t gateway that they give you and I'm looking to replacing it or attaching a router to it if that would fix my issue.
