Or simply run the personal hotspot from your mobile and connect your laptop/pc with that. That's what I do when I have an unstable internet connection and I know that I'm going to play an important game or a tournament where I can't afford to let a bad connection interrupt my games and ruin my hands if I have good ones. I have also experienced this on quite a few occasions in the past, and I have learned from those mistakes/experiences, and that's why I always make sure that my internet connection is working fine before I get started.

The idea of having your account logged in on your mobile phone is a good one as well. I have my SwC account ready to be logged in on my mobile as well, this makes it handy for me to play when I'm not at home. You can't carry your laptop around unless it's absolutely necessary, but you have your mobile at all times. Besides, the layout and gameplay on mobile phone is amazing.
