download freezes

Hi all,

I have an 8ta micro sim card, I've been using my phone(galaxy s4) as a mobile hotspot.
I'm trying to download a file(297mb) on my laptop. Each time the download gets to 221mb, the download freezes. I tried it 3 times, and the same thing happens.

Does anyone know what could be the cause of this and how can I resolve the issue?

Thank you
