First, what package name do you have exactly? According to here, the highest package is "Go Beyond Fast Internet" which is 2000/2000.
Next, what model router do you have? Is it slow on wired as well as wireless?
Finally, if slow on both, have you tried connecting direct to the ONT and running a speed test? The ONT is the device installed by Cox to turn fiber into ethernet and is probably made by Nokia.
Overall it sounds like a 10/100Mbps bottleneck from a bad ethernet or bad port.
Are you asking if OP has ever measured anything over 100 Mbps?
Yes, I guess so. I assumed they haven't since they said they only get 93Mbps on a "good day".
...only get 93 Mbps on a good day after the upgrade.
I'm just soliciting more info from OP by asking you.
