Packet Loss, Latency

Just started Comcast business internet yesterday, and I'm starting to regret it.  Can't use VOIP phones due to high latency and dropped packets, speedtest shows about half of the download speed we're supposed to have.  Using PingPlotter Pro, got these results.  Called tech support, said our modem is fine, no surprise, said we needed to unplug everything (SonicWall firewall and switches) and do speedtest directly at the modem. I'll try, but we had no internal issues before we switched.

 

I'm not a network engineer, but I think Comcast needs to raise hte issue with level3.net support.  Is anyone else having similar issues?

I have a similar issue from Las Vegas => Denver, CO.  Here's what I see; Every. Single. Day...in our icinga2 Monitoring:

I've highlighted the (already obvious) issues.  It is littering our monitoring system with garbage and I cannot, for the life of me, figure out what's going on with the connection.

 

We've never had to be notified for these issues since it typically happens 1/5 checks before sorting itself out.  It does not seem to be related to the connection at the monitoring node, either, as I've monitored it myself from a few other endpoints and I've seen the high RTA Ping.
