I cannot seem to find anywhere what the download and upload speeds are supposed to be for ATT internet. I'm clocking in at a blistering 4.25 Mbps download and 0.25 Mbps upload speed. For what we're paying, this is unacceptable. 4.25 down is... fine; good for one person on one device viewing a single video or whatever. But 0.25 up borders on non-functional. Why is it like this? Is this the intention of ATT?
