Curiosity. When I used to play video games I would stress over latency. Since I don’t play video games it’s just one of those things you do so you can throw a snide comment to the effect of my WiFi at home is faster.
1. Determine if there is something wrong with the internet
2. Check VPN - sometimes VPN throughput is slow for some reason from the provider
3. Fault finding - sometimes download speeds are slow but line speeds are fine
4. Have LTE so like others mentioned, check line speed on different frequencies i.e 2300mhz
To see whether my crap internet is a bit slow, or faster for the day, and to enter competitions.
Also to test my VPN connection to my US-based VM. (Playing around with the OpenVPN config for optimal speed)
Mostly when I am at my parents, I also test there because they complain they pay for a 4mbit line, but dont know why DSTV Now buffers so much...(internet a bit slow) Maybe needs 6mbit line. Their ISP is an local wisp, so they can change the line speed in a click.
