Mainstream Fiber Networks provides fiber to the home, business, and beyond. We do not stop at the utility poles with our fiber, instead, we deliver fiber from the pole directly to wherever it may be needed.  We are constantly growing our network in Washington to better serve the residents there.


We are a locally owned and operated fiber optic internet provider based out of Nashville, Indiana. Our local team is dedicated to delivering comprehensive community infrastructure and a superior broadband solution to rural communities throughout Indiana.
