Charter is contending 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.

Many current Spectrum internet customers got an automatic speed upgrade. New Spectrum customers can get internet as low as $30 a month when bundled.
