Upload Intermittently Slows to a Crawl for Gigablast

Hello,

The Gigablast internet service I have hasn't been working well lately at all. The download is fine, but the upload has been slowing to a crawl at times. It's getting to the point where there are periods I cannot work. This has been going on for a couple weeks too. 

Yesterday morning (10/5) I couldn't get it to upload faster than 0.1~0.2Mbps. Then around 10:00 am the regular 35 Mbps speed resumed. I called support a couple times and was told I do have some packet loss, but everything else looked fine. Everything came back to normal after a few hours. 

Today (10/6) everything has been fine until this evening, and it seems like only partial content loads on web pages and the upload is slightly faster at 1.1 Mbps. 

It happens though wired, wifi, and direct connect to a PC connection to the modem. Would congestion have it so wildly change like that?

I ran a tracert and I seem to be getting some packet loss or slowdown. This is going to cox.net.

I have a Motorola MB8611 and no events are showing up in this timeframe. I just find it odd that the download works perfectly fine and only the upload is affected. Here is the connection data from the modem:

Should I call and have a tech come out? I never called support back the 2nd time because it came back.
