I was on zen 150 / 30 until yesterday and on WiFi I only got 80 down and 30 up.
This morning my upgrade went through to 300 / 50 and now on WiFi I get 280 / 50.
Why when the hardware has stayed the same has my WiFi increased to well over what it could previously provide when it's same equipment. What stopped it giving me the full speed before the line upgrade?
