| [Windows] ADSL 4100 ft 900ms latency
Our business has 2 Covad DSL connections. Our SDSL 768K is awesome. We use VOIP over the internet with it and pings are 19ms consistently. Voice quality with G711 is awesome.
We also have an ADSL 8/1 connection in the office for internet connected to our firewall/data network. I connect from home - Verison FIOs 10/2 (VPN/Remote Desktop) to that network and it crawls. I check ping times periodically and I get ping times close to 1000ms, but consistently at 500ms. Occasionally, I see ping times in the teens and the remote desktop moves nicely. Usually, it sucks. When I ping and check a speedtest from my home network without being connected to the VPN, pings are in the teens and I see close to 10/2.
Covad changed the backhaul and when they do it, ping times drop to the teens for a short while then move to 500s. They ping their router and see the ping times. They sent a tech out and he saw nothing wrong. My IT people said they isolated the problem by removing our network and saw slow speeds before the network. We disconnected the network and Covad was unable to ping the router.
Bottom line, something is wrong because my remote experience is awful on the ADSL and ping times are clearly unacceptable. The other DSL line is amazing and we are 4100 feet from the CO.
Help!!!!!!!!!!!!!!! Can my network with outlook, a database called goldmine, and not much else be causing the problem? |

| What are you using to run the VPN on your end? windows or a piece of hardware?
If using windows did you make sure to turn off "Use default gateway on the remote network", if its on all of your traffic on that computer goes though the VPN not just work stuff, so your ping will have a high latency to say google.

Note you might have to leave it on depending on the network setup, I'm not sure.

| The office network accepts incoming vpn calls. I connect from Windows vista to a piece of hardware, I believe. Once I am connected, if I ping something from my pc, I believe I get speeds thru the VPN. I am not sure this is significant because when I disconnect from the vpn, pings to my office network ip address are still 500-1000ms. |

Block out the remote IP/Name. |

| There something up on the connection used for the VPN ethier the line is having issues, the DSLAM its on is having issues or the line is being overloaded.
My guess would be to check traffic levels, I betting something is using all of the bandwidth witch could cause this.

| Covad has looked at utilization and noone is in my office now. Utilization has been very low. There are 6 people in my office. We use Outlook, Goldmine (a relationship database with a sequal server) and regular internet surfing (noone is surfing right now). Covad says it is my network causing the high pings and slow speeds and my IT people say there is nothing on my network making that happen. Aside from workstation enduser streaming, etc., what on my network could be creating such high ping times and slowing speeds? We get nowhere near the 8/1.
Covad ADSL 8/1 comes into my office, ethernet plugs into Covad supplied motorola router supplying 5 static IPs. Our office firewall is a rideway and is has a static ip address, after that is our network with harddrive server, database server and outlook server. What could cause the problem?
Very frustrated. Thanks. |

Milledgeville, GA | Any Chance you can provide a tracert from work to say google?
If you can leave the private IPs and * out the last 2 sections of the public Ips, that way we can see where the problem starts hopefully. |

1 edit | Will do that tracert, but just did one from home to office and got below results. Is that weird? And pings are in the 100s 200s 300s 30s 40s 20s, very varied. Maybe after 5p it goes bad, not sure.

Columbia, MD | not sure if it matters, but ping from desktop to my firewall is low, to router is low and ping to google.com is in the 3, 4, 5 and 600s. Does that mean it is not my internal network that is causing the problems? Covad continues to blame my network. |

| It means its looking more like a covad problem, have you tried a different modem on that line to test? Maybe when possible just use a modem and computer connected directly to it just to rule everything else out and make covad dig deeper on there side.

Most likely they are getting errors on a network backbone in the CO. Try the 'pathping' command and see if it shows any errors. |

| "pathping www.google.com"
or where ever you want to path ping to.
But I dont see what its going to tell you that we don't already see.\
The next trouble shooting step is to try a different modem and have a computer directly connected to it at a time when you see the elevated pings, if you still get them then it up to Covad at that point to track down and fix the problem.

Columbia, MD | Our office IT people told me they run a backup of our servers over the internet to their office. The backup can take 4 hours or so every night. Could that internet traffic increase ping times to 4, 5, 600 or higher? |

1 edit | said by glassr  :Our office IT people told me they run a backup of our servers over the internet to their office. The backup can take 4 hours or so every night. Could that internet traffic increase ping times to 4, 5, 600 or higher? Certainly that could increase your ping if your line is choked with net traffic because ping is low priority (and not actually required at all except for testing).
We have AT&T branded Covad 1.5 mbps SDSL (from before AT&T remerged with SBC), and have only had issues with it once in many years (bad connection on card in telco CO). We use SonicWall routers for VPN to our factory 1700 miles away for 6-8 PC's and 2 printers that print from factory (besides locally). Although, our factory has a DS3 connection because it has many VPN's connected to it. |
