The distance between you and a hotspot can be an issue, but it's not what causes slow internet connections. The hotspot's data plan with whatever internet service provider is being paid is the bottleneck. It might be a slow, cheap plan; in that case, there's nothing to be done to speed up the internet but buying a better data plan.
Also, you have a very slow computer. Slower than an iPad, actually. 1 core @ 1.2ghz.
Do you have a link to an info page about that notebook? I've had trouble finding any information not scattered all over the web. It's probably using its motherboard's integrated graphics processor, which is terrible. You can't upgrade it, unfortunately, because it's a laptop.
