@Zuke here, in my area, people also use like 40 or 50 or at the most, 100 Mbps. Only I am the one using their unreleased 300Mbps plan (upgrading from 200Mbps) and I am satisfied. Yesterday tho, I bricked my XC220-G3v while upgrading it to a new brazilian firmware (the blame is on me), and now I am deciding which ONU to buy ( I have an AX1500 router, no ONT needed).
