Non-stop packet loss and speed dips.

Hello,

Iv been getting 30%-100% packet loss for about 3 days now. Just wanted to see if anyone was able to spot errors that i cant. I need the internet to make a living so any help would be amazing, thanks.

I had one tech come out yesterday and he somehow got it to stop for about 3 hours by removing a splitter (no idea why it was installed in the first place).
