Meet MegaWatt Fiber, Your Hometown Internet Provider

Born and built right in Lewisburg, MegaWatt Fiber isn’t just another internet company — we’re your neighbors, your friends, and part of what makes this community special.

Since 2009, we’ve been dedicated to bringing the fastest, most reliable internet to Lewisburg and Cornersville because we believe small towns deserve big technology.

Founded by Jack Cathey, a lifelong resident, Jack created the brands DualFusion and MegaWatt Communications. MegaWatt was created with one goal: to give our community world-class internet without sacrificing the small-town service you expect. When you call us, you get real people, real answers, and real support from folks who actually know and care about you and your family.

We’re here for you, because we are you. So whether you’re streaming, gaming, working, or just catching up with family, we’re proud to keep you connected — with the speed and hometown service you can count on.

Now Part of the RingSquared Team of Brands
In 2025, MegaWatt Communications proudly joined RingSquared, a national provider of voice, internet, and cloud connectivity solutions. This partnership strengthens our ability to deliver fast, reliable fiber internet by combining our local expertise in Tennessee with RingSquared’s growing fiber network and nationwide infrastructure. Together, we’re accelerating fiber expansion into more communities—while continuing to deliver the same great service our customers count on.
