Can I boost my internet Mbps?

You are stuck with 1.5. Think of internet as having a water pipe that connects you to the internet, the problem is that you want a 10" pipe to transfer alot more data but they only have a 1.5" pipe that goes to your house. Unfortunately you can not add pipes nor increase the pipe size, that is up to the ISPs.

On a side note, you can look into satellite internet which I think they can give 10 Mbps but latency might be an issue (delay from when you send info for it to come back to you would be likely 0.5-1.5 seconds).
