Hi. I am a CSE student from MSRIT and it is an amazing college with a great campus. I personally didn’t like the BIT campus very much (when i wrote my COMEDK 4 long years ago in that college).
Regarding internet in the MSRIT, all labs have LAN connection and some of them even have their own WiFi ( The CS lab for instance! 😀 ). And there is common WiFi available throughout the campus (though it doesn’t work in all the places in the campus).
And coming to clubs and co-curricular activities in MSRIT, there are plenty of clubs and events!
