[Student] Sophomore (Upcoming junior) aiming at networking focused SWE roles looking for advice

Im currently a sophomore has been investing a bit of my interests into networking systems (stuff like TCP/IP protocols BLE stuff like that) and was wondering if im heading in the right direction. Am i also pidgeonholing myself by picking a niche area to go into this early?

I am also struggling to find a internship this summer and i am very stressed about it, is it easier for juniors?
