Frequently asked questions
What internet speed do I need for a family of 4?
A family of 4 with typical usage (HD streaming on 2–3 devices, 1 person working from home, light gaming) needs 100–200 Mbps. If anyone streams 4K or has multiple video calls, aim for 200–300 Mbps for a buffer.
What is the difference between Mbps and MBps?
Mbps (megabits per second) is how ISPs measure internet speed. MBps (megabytes per second) is how file sizes are measured. There are 8 megabits in 1 megabyte. A 100 Mbps connection can download at ~12.5 MB/s.
Why is my internet slow even though I pay for fast service?
Common causes: Wi-Fi interference or weak signal (use a wired connection to test), ISP throttling during peak hours (evenings), outdated router or modem, too many devices competing for bandwidth, or actual service issues in your area.
Is 100 Mbps enough for a household?
100 Mbps handles most households of 2–4 people with HD streaming, video calls, and casual gaming. It may feel tight with multiple 4K streams or competitive gaming. For future-proofing, 200–300 Mbps is a good choice at today's prices.
How do I check my current internet speed?
Use speedtest.net (Ookla) or fast.com for a reliable measurement. For the most accurate result, connect your device directly to the router with an Ethernet cable and run the test when no one else is using the internet.
