Only downloading at 2 - 3 Mbps? Can I make this faster?

Origin tells your speed in MB/Sec = megabytes downloaded per second.

Internet service providers typically tell your speed in Mbps megabits per second(not to be confused with MBps which is the same as above).

This means:

30Mbps = 3.75 megabytes per second which means anything around ~3.5 megabytes per second should be expected if you are not downloading other things and are using a cabled connection.
