Packet Loss langbprj01-ae1.rd.la.cox.net

https://ibb.co/NZPBsQv

Howdy!   I've been doing several mtrs in the past 30 days from our network to meet.google.com, Zoom, and 8.8.8.8 and I'm getting packet loss & jitter.

I am using a Cox Gigablast Modem, connected to Cox Orange County, speedtest.cox.com is yielding a whopping 960Mbps down and 30Mbps up, I am directly connected to the cable modem via ethernet, my wifi is turned off, and I get packet loss averaging 1.8% and as high as 5% (which cuts my video and audio calls at home during the pandemic).

Could you please offer some advice?   

This seems to be the offending gateway:  langbprj01-ae1.rd.la.cox.net - 1.8% Packet Loss

  • It is normal for the middle hops to have failed pings on a traceroute due to traffic prioritization. As long as you have no loss on the destination the packets are making it there.

      Thank you for the quick reply.   When/if I have an issue again I'll try to capture the far end having loss.   So far so good right now.

        langbprj01-ae1.rd.la.cox.net Always drops packets, not just pings.  Witness as UDP (which game packets generally are.)

        This is not normal.
