Looking for advices to stay motivated working with my master degree advisor
I did my bachelors and master degree in Mathematics in one of the country's top institute, but due to some reason, I am currently doing my Ph.D. in Electrical Engineering department in another country and the university is also top in the country. 

After joining Ph.D., I realize that as a Mathematics student, I do not like the research problems given to me by my supervisor. But there is one problem in which a lot of probability theory (very advanced level) is needed. I have started on my own to tackle this problem and after a year or so I have on my own progressed and published and also found a few other workable problems completely from a probability theory perspective. If I progress on these problems and publish then I am sure within the next 2–3 years I can start writing a thesis. 

I must tell you since my supervisor is not a probabilist there is zero input from his side. I hope you can do on your own too. I feel sometimes the same way as you. But I really like the area I am in now. So at the end of the day, you have to find a problem and solve it, there will be rarely you and your supervisor both thinking and solving the problem together in my opinion.
