Question 1

What is a good internet speed in 2026?

Accepted Answer

For most households, 100 Mbps download and 20 Mbps upload is comfortable for 4K streaming, video calls and remote work. Heavy households with several 4K streams or large uploads benefit from 300–500 Mbps.

Question 2

What is an Internet Fitness Score?

Accepted Answer

The Internet Fitness Score condenses download speed, upload speed, ping, jitter and packet loss into a single 0–100 number, then rates your line for streaming, gaming, video calls, remote work, browsing and downloads.

Question 3

How accurate is an online speed test?

Accepted Answer

A browser speed test measures the real throughput between your device and the closest test server. It is accurate for the moment it runs, but WiFi interference, VPNs, background downloads and busy hours can all move the result.

Question 4

Why is my speed test slower than my plan?

Accepted Answer

Advertised plan speeds are the maximum at the router. WiFi loss, older devices, network congestion, throttling and overhead typically shave 10–30% off the number your provider promises.

Question 5

What is ping and why does it matter?

Accepted Answer

Ping (latency) is the round-trip time in milliseconds for a packet to reach a server and return. Below 30 ms feels instant, 30–60 ms is fine for most games, and above 100 ms causes noticeable lag in calls and gaming.

Question 6

What is jitter?

Accepted Answer

Jitter is the variation between consecutive ping measurements. Low jitter (under 10 ms) keeps voice and video calls smooth; high jitter causes robotic audio and frozen frames even when average speed looks good.

Question 7

What is packet loss?

Accepted Answer

Packet loss is the percentage of data packets that never arrive. Anything above 1% degrades calls and online games because lost data has to be re-sent.

Question 8

Download vs upload speed: what is the difference?

Accepted Answer

Download speed governs how quickly you receive data (streaming, browsing, game downloads). Upload speed governs how quickly you send data (video calls, cloud backups, live streaming, sending large files).

Question 9

How often should I test my internet speed?

Accepted Answer

Test once when your line is installed to get a baseline, then monthly, plus any time performance drops. Testing at peak hours (roughly 8–11 pm) reveals congestion your daytime tests will miss.

Question 10

Should I test over WiFi or Ethernet?

Accepted Answer

Test both. Ethernet shows what your line can really deliver; WiFi shows what your devices actually experience. A large gap points to a WiFi problem rather than a provider problem.

Question 11

Does a VPN slow down my speed test?

Accepted Answer

Yes. A VPN adds encryption overhead and routes traffic through a remote server, which usually reduces throughput and increases ping. Disable it for an accurate baseline test.

Question 12

What internet speed do I need for 4K Netflix?

Accepted Answer

Netflix recommends at least 15 Mbps per 4K stream. Allow around 25 Mbps per stream in practice so buffering does not appear during busy periods.

Question 13

What internet speed do I need for gaming?

Accepted Answer

Competitive gaming needs stability more than raw speed: 25 Mbps download, under 40 ms ping, under 10 ms jitter and 0% packet loss will outperform a fast but unstable line.

Question 14

What is the difference between Mbps and MB/s?

Accepted Answer

Mbps is megabits per second, MB/s is megabytes per second. Divide Mbps by 8 to get MB/s. For example, a 400 Mbps line downloads at roughly 50 MB/s.

Question 15

Why does my speed change at different times of day?

Accepted Answer

Shared infrastructure gets busy during evening peak hours. Cable and fixed-wireless networks are most affected; fibre lines hold their speed far more consistently.

Question 16

Can my router limit my speed?

Accepted Answer

Absolutely. Older routers with 100 Mbps ports or WiFi 4/5 radios cap gigabit plans. A WiFi 6 router with gigabit ports removes the bottleneck on most modern plans.

Question 17

Does this speed test store my data?

Accepted Answer

No accounts, no logins and no tracking profiles. Your test results stay in your browser session unless you choose to share them.
