Sorry my bad, I checked and thats 4 mbps down and 2 mbps up that I am 
paying for.
My PC has "N" mode nic and I get 130 mbps wifi connection.
My test is 1.24 mbps down and .82 mbps up between 
Cleveland Ohio and Angeles City Philippines. My ISP is 
Angeles City Philippines.

So I come back to the question is the internet download speeds up to 38 
mbps and upload speeds up 30 mbps of the Motorola SB5101u cable modem 
acting as a bottleneck? Is there a better cable modem that is not 
limited I should be asking my ISP if I can use?
