The rollout comes as Charter contends with slowing broadband customer growth, defections from the cable TV bundle, and a young, expanding mobile business.

Internet service provider Spectrum announced changes Monday including increased minimum speeds and guaranteed pricing for three years with bundled services. The changes also include a pledge to address service disruptions quickly, dispatching a technician the same day if requested by a customer before 5 p.m.

All Spectrum Internet and Spectrum Internet Ultra customers will have their internet speeds automatically increased by 100 Mbps each to 400 Mpbs and 600 Mpbs, respectively — a free upgrade, according to a Sept. 16 news release.
