Centurylink DSL, 20meg, Technicolor C2100T, Fedora
So every once in a while I click on a link and nothing happens for several seconds or streaming a video, buffering, and it got annoying. So I set up a testing script using speedtest-cli, MariaDB, and Phplot. I run speedtest-cli every 5 minutes and I'm surprised. On a regular basis, every 90 to 100 minutes my speed drops from 19Mb to less than 10Mb. And sometimes it drops to less than 1Mb. IE .2Mb and stays there. Centrurylink says I have too many DHCP reservations and to remove them :-\ or they want me to disconnect every device, turn off WiFi and run a speed test - Hey look it's 20Mb, there's no problem.
I don't have anything internal that runs on the schedule I'm seeing
Suggestions? Thoughts as to the cause. Thanks for any advice.
Each tic mark is 5 minutes. Red is download, green is upload
Speed dropout
It is possible that there is some periodic interference causing the DSL line to lose sync, or the modem to sync at a lower speed for a bit. I would look into the modem stats page, and see what signal levels you see. There is some basic reference about DSL signal levels here:

I hope this helps

Glad to hear you figured it out! Cloud backups seem to be an often overlooked bandwidth guzzlers I suppose. You can always tweak it by reducing the amount of data being backed, and limiting it's bandwidth too.
Thanks for sharing.

There may be a problem with the integrity of the cable connection. Sometimes I lost speed when running some programs. It is also possible that the speed is lost when updating background applications.Philip wrote:Glad to hear you figured it out!
