MiFiber Is Now Core Fiber

October 2, 2026

MiFiber has spent years bringing fast, dependable fiber internet to homes and businesses across northeastern Washington and western Idaho. Now, that work is continuing under a new name.

MiFiber is now part of Core Fiber.

For existing customers, this isn’t about walking away from what made MiFiber valuable. It’s about building on it.

MiFiber was created around a simple idea: communities outside major metro areas deserve access to modern fiber infrastructure, too. That focus helped bring high-capacity internet to communities across the region, including places such as Newport, Washington, and Priest River, Idaho, where Core Fiber continues to provide fiber internet today.

Joining Core Fiber gives that network a larger platform for what comes next.

Fiber built for how we use the internet today

The way households use the internet has changed dramatically. One connection now has to support video calls, streaming, gaming, cloud applications, smart-home devices, schoolwork, and dozens of connected devices at once.

Fiber was built for that kind of demand.

Unlike technologies that were adapted from older infrastructure, fiber can deliver enormous amounts of data with very low latency and strong reliability. Core Fiber’s current residential network offers fiber plans ranging from 500 Mbps to multi-gig speeds, depending on location.

That makes MiFiber a particularly natural fit for Core Fiber. Both share the belief that smaller communities shouldn’t have to settle for yesterday’s internet technology simply because of where they live.

More than a network upgrade

Fast internet matters, but the experience around it matters too.

Core Fiber is built around the idea that customers shouldn’t have to choose between the capabilities of a large network and the service of a local provider. That means straightforward pricing, dependable connectivity, and access to real support staff based in the US (and never a bot) when you need help.

Every Core Fiber customer is assigned a Core Advocate who serves as a consistent point of contact for support.

That approach closely matches the broader Core Fiber promise: reliable service, clear communication, and support that feels close and personal, not distant or corporate.

For MiFiber customers, the goal is to pair the fiber network they already rely on with additional resources, technology, and support as part of the larger Core Fiber organization.

Ready for whatever comes next

Internet usage isn’t slowing down.

Homes are adding more connected devices. Businesses are relying more heavily on cloud applications. Entertainment is shifting toward 4K streaming and internet-delivered television. Remote and hybrid work have made a reliable home connection essential for many households.

Fiber provides the capacity to handle those demands today while leaving room for what comes next.

Core Fiber’s current network supports everything from everyday 500 Mbps service to multi-gigabit plans in select communities, giving households and businesses room to grow as their connectivity needs change.

That makes the transition from MiFiber to Core Fiber less about changing direction and more about continuing down the same path.

A strong local fiber network. More resources behind it. And a continued focus on the people and communities that network was built to serve.

MiFiber is now Core Fiber, and we’re excited for what comes next.
