Please see https://www.dslreports.com/faq/14068. The fact that the hops after the one you are concerned about received trace packets indicates that the router there is doing its job: forwarding data packets. The hop 6 router's occasional delay in or failure to respond to trace packets, while annoying, is most likely not actually slowing down data transfer. If it was we'd see high RTT values and/or packet loss in the following hops, and we don't. You may indeed have a communication problem, but the trace does not show that.

Interpreting trace results is tricky. What appears to be "late" or is reported as "lost" could mean 1) the packet did not reach or was delayed in reaching that hop, or 2) the router at that hop didn't reply or was slow to reply, or 3) the reply from that hop didn't make it back or was delayed in making it back to the trace program.

This problem completely cleared up on the 1st of the month.. Which leads me to think there was some kind of throttle on my account until Jan 1st... Even though I pay for unlimited....

user_04tqn5 Thanks for letting us know the problem has gotten better, but throttling for any reason isn't something we would do for our customers. Should the issue return or get worst, please let us know.
