Comcast Business Speed Test FAQ
How fast is Comcast Business internet?
Comcast Business offers speeds from 150 Mbps to 1 Gbps depending on plan and location. Cable plans use DOCSIS 3.1 technology and deliver reliable business-grade performance. The Advanced 1Gig plan uses fiber for the fastest speeds. Upload speeds on cable plans are lower than download speeds. Comcast Business includes service level agreements and 24/7 support not available on residential plans. Run a speed test to verify your current Comcast Business connection performance.
How is Comcast Business different from Xfinity?
Comcast Business is the commercial division designed for businesses, while Xfinity is the residential consumer brand. Comcast Business includes static IP addresses, service level agreements with uptime guarantees, 24/7 priority business support, and options for dedicated fiber circuits. Business plans typically cost more than comparable Xfinity residential plans but include enhanced reliability guarantees and business-specific features. Using residential Xfinity service for a business may violate Comcast's terms of service.

Does Comcast Business offer fiber internet?
