New York, NY | TWC NYC (Manhattan) Business Class - Packet Loss Issue! Hi Everybody!
I have been fighting with this issue for weeks now. We are experiencing packet loss on one specific node in NYC on timewarner's/roadrunner's network which causes our network to experience drops in connectivity with our phone SIP provider.
TimeWarner sent a tech out who was clueless to the problem.  He was on the phone with somebody who told him to up the signal strength, then down the signal strength, etc. I think this was totally pointless as my traceroutes show exactly what the problem is and where.
Anytime we traceroute sites like google, facebook, cnn, or dslreports.com, we go through the same node/hop which clearly has an issue, thus the packet loss percentage.
For these tests, we eliminated any hardware in between. Tests were run from a laptop connected directly into the modem.
I want to know if anyone else in NYC is experiencing this issue and if so, how we can get this problem resolved with timewarner. |

If you have problem with phone I suggest doing voip packet loss tests, it wouldnt take much to drop calls, I think about 2 % upstream loss. |

Long explanation for hobgoblin  's reply:
Trace route sends a series of packets with TTL ("Time To Live") flags, of variable value from 1 up to the maximum number configured (30 for the "maximum of 30 hops" in a standard Windows trace).
Each router in the path decrements the flag, then tests for "zero". A non-zero value is forwarded to the next router up the line. A "zero" value is discarded; and, maybe, the router sends a return packet. If a packet is sent, you will see a line with the RTT ("Round Trip Time") displayed. Otherwise you see no response.
The lack of a response from any one router, as you are showing, with a subsequent router responding 100% of the time, only means that the non-responsive router is ignoring ICMP (Windows 'tracert'), not that there is packet loss.
Hence why hobgoblin is saying that there is no problem shown in your posted trace routes.

Is your VOIP provider in question 8x8 by any chance? |
