I think you mean 300KBps (KiloBYTEs)
Remember that you need to factor in the location and speed of the place you are downloading. You have a maximum bandwidth of 34Mbps, but that doesn't mean you will get that for everything you download. You max download speed will be about 3-4MBps tops, but again, that is not a guarantee, and is based on where you are downloading from, and any other network traffic going on, be it someone in your house streaming Netflix, or many people downloading the same thing elsewhere in the world.
Overall, working as intended.
