Broadband Speed FAQ
Everything you need to know about broadband speed, download times, and choosing the right connection.
For most households, 50 to 100 Mbps is enough for HD streaming, video calls and browsing on several devices at once. Larger households with multiple 4K streams, gaming, or remote work typically benefit from 300 Mbps or higher.
Mbps stands for megabits per second and is how internet providers advertise speed. MB/s stands for megabytes per second and is how file sizes and download progress are usually shown. Since there are 8 bits in a byte, you divide Mbps by 8 to get MB/s.
Download time is calculated by dividing the file size by your actual throughput in megabytes per second. Since broadband speed is advertised in megabits, it is first converted to megabytes by dividing by 8 before the calculation.
Yes. Wireless signal strength, distance from the router, interference from other devices, and the number of connected devices can all reduce real-world speed below the plan’s advertised maximum.
