I have just upgraded to the Ultra Fast 1000Mbps connection where you expect 650Mbps in peak times.
Since being installed last week I have not seen it go over 138Mbps download, 38Mbps upload at my router using a TP-link router capable of up to 1.4Gbps.
A friend of mine who lives 15mins away is having the identical problem after he changed over 1 week ago but he was unaware until I told him.
I performed the Ookla Speed test at the NBN box and got between 300Mbps and 380Mbps. This is telling me AGL might have some bandwidth issues or are throttling internet connections but still selling the product to customers.
The router has all of the AGL details loaded and it is a fresh FTTP install.
Perhaps consider holding off on going to the Ultra fast for now as it doesn't seem like they can deliver what they are selling. Feels like I bought a Ferrari but they provided a Honda Civic.
