Playing Silkroad through tethered smartphone?

[Kaninstek]

Hi, I was just wondering if there is a way to maximize data transfere while tethering. I use "Mobile AP" and connect with my laptop wirelessly. Thing is, I was wondering if there is a way I can temporarily prevent my phone from connecting to the internet itself, leaving more connection-space for my laptop.

I was thinking something like flight-mode, my thinking being that maybe it prevents unnecessary internet-usage.

Sorry if it's hard to read, english is not my mother tongue!

Edit: Oh and I use Android

Most phones got an option where you it stops the phone from connecting to wireless networks, Try going to settings -> connection (or something like that).
