No, you cannot increase the speed of the connection. You may be able to increase its throughput, that remains to be seen.
I am guessing that you are concerned about throughput to the Internet. First question, what kind of a connection do you have to the Internet? "Crazy" is not a tangible measurement. Your upstream numbers will likely be different than your downstream numbers, and it does make a difference which is which.
I seriously doubt that you have more than 93.92 Mbps upstream to the Internet, therefore your network is already FASTER than your internet connection. No tweaking needed.
