Northeast for Digital Nomads.

Hello guys, I (25M) am from Karnataka. Since I was in 5th grade, I have always wanted to bag pack across northeast India. Pictures from Northeast always mesmerize me. I have decided to travel and stay in northeast for 6 months starting March. I want to work there while experiencing different cultures across 7 sisters of India. I have been to Guwahati before and was only there for one day (maa kamakhya temple) in 2024 and I loved it! The idea is to travel to Guwahati first and hop hostels/hotels in different cities every week or two weeks till I cover all the 7 states. I have heard there is a special permission I have to take to travel there. I have also heard getting stable Internet in some parts is a problem, I am the kind of person who despises planning so since I am solo travelling I will be very flexible. This will be my first time working from different places. Do you guys have any tips or suggestions for me? Thank you!
