Frequently Asked Questions — EarthLink Business vs Spectrum Business
What is the difference between EarthLink Business and Spectrum Business?+
EarthLink Business is a managed WAN aggregator — it provides a single managed solution by combining fiber, cable, DSL, and wireless from multiple underlying carriers. Spectrum is a direct provider owning its cable and fiber infrastructure in 41 states. EarthLink is better for multi-location businesses needing consistent management across diverse geographies; Spectrum is better for single or few-location businesses in its direct footprint.
Is EarthLink a real internet provider for business?+
Yes — EarthLink Business is a legitimate managed network services provider. It operates as an aggregator, reselling and managing last-mile connectivity from multiple carriers under a single managed service agreement. This model is well-suited for multi-location businesses with distributed footprints.
Can EarthLink and Spectrum serve the same business locations?+
In some markets, EarthLink can provision Spectrum's underlying cable service as part of its managed WAN. In this case, they're not directly competing — EarthLink is adding management and aggregation on top of Spectrum. For direct access to Spectrum's service without the managed layer, Spectrum direct is typically more cost-effective for single locations.
