Frequently asked questions

Why is my download slower than my advertised speed suggests?+

Advertised speeds are usually in megabits per second (Mbps), while file sizes are in megabytes (MB) — 1 byte = 8 bits, so actual download speed in MB/s is roughly your Mbps divided by 8, plus real-world overhead.
