Comcast to extend multi-gig, symmetrical Xfinity Internet to 5,500+ homes and businesses in Wisconsin

Comcast said it is expanding high-speed, symmetrical Internet service to more than 5,500 new homes and businesses across Manitowoc County and St. Croix County in Wisconsin. The company plans to bring the upgrade through its Xfinity brand, describing the planned network as “multi-gigabit” and symmetrical, meaning upload and download speeds are designed to run at comparable levels for more consistent performance.

The buildout, Comcast said, will span nearly 300 miles of network across both counties. Construction activity is already underway, with the company targeting first customers to become serviceable by the end of 2026 and the broader project completion by the end of 2027.

Comcast said the upgrade is part of its “converged network,” an approach that supports multiple services over the same network infrastructure. In addition to Internet, Comcast tied the expansion to providing customers access to its Xfinity Mobile, plus “internet, mobile, entertainment, and smart home services” packaged into a single experience, in the company’s description of what subscribers can manage through Xfinity.

In Manitowoc County, Comcast listed specific townships included in the expansion: Cato Township, Centerville Township, Liberty Township, Manitowoc Rapids Township, Manitowoc Township, Meeme Township, and Newton Township. For St. Croix County, Comcast did not include the full list of affected communities in the text available here, but it confirmed that both counties are included in the project.

Comcast framed the investment as bringing connectivity to areas it said “need it most,” with the stated goal of helping families and businesses work, learn, and operate in a digital economy. Kalyn Hove, Regional Senior Vice President for Comcast Midwest, said the company’s network expansion is intended to provide the high-speed, reliable Internet residents require, and to pair that with Xfinity Mobile for a more connected experience both at home and on the go.

The announcement comes as cable operators face ongoing competition from fiber-to-the-home providers and fixed wireless internet offerings in many parts of the U.S. Comcast’s emphasis on symmetrical, multi-gigabit service reflects a broader industry shift toward higher upload capacity for activities such as video calling, cloud work, and creating or sharing content, which can be constrained on older networks.

Even with the project details, Comcast did not disclose the exact expected speed tiers for the new service areas, nor did it provide information on the total budget for the Wisconsin expansion in the available announcement. The company also did not address whether all planned addresses will receive the same capabilities at launch or whether speeds could vary by location depending on construction progress and local network conditions.

For residents and businesses, the key near-term marker will be Comcast’s timeline for first serviceable customers by the end of 2026, followed by network completion by the end of 2027. The company did not provide an address-by-address activation schedule in the available text, so affected customers will likely need to monitor Comcast’s rollout updates to confirm when service is available. The company’s follow-through on symmetrical multi-gigabit performance in the newly connected areas will also be watched, since that is central to Comcast’s pitch for the upgrade.
