Use pingtest.net not speedtest.
Also how often do you restart your modem and router?
You could try a factory reset on your modem and router, set them back up and see if that'll fix it, you could also look into TCPAckFrequency, call your ISP and ask about Fast Path, Check and make sure that all devices(except modem) have a filter on them when plugging into the phone line. Also if you have an alarm system on your home, you could ask for a splitter from your ISP.
Those are all things you can try, if you still have high latency. It's more than likely on their end. Unless it's only on one computer.
Said this in another post, I should save this somewhere I've been typing identical a lot >.> lol. But yeah, some of those are only for DSL, so if you have cable or fios, some of those aren't an option.
But from the looks of how much it's jumping around I'd say you may need a new ISP. Do you share your connection with anyone?
