+10 to Erik's questions below. Use tracert (as suggested by Mike Sullivan) from inside your LAN and from connected directly to your cable modem with a laptop (as suggested by Dennis Hoefer), and then you'll know where to point the finger.
Example: C:\>tracert 4.2.2.2 Tracing route to vnsc-bak.sys.gtei.net [4.2.2.2] over a maximum of 30 hops: 1 3 ms 1 ms 2 ms [Private IP Address removed] 2 3 ms 1 ms 1 ms rrcs- [Public IP Address removed] .midsouth.biz.rr.com [Public IP Address removed] 3 1 ms 1 ms 1 ms [Public IP Address removed] 4 4 ms 4 ms 3 ms ten2-0-0.gnboncsg-pe-rtr01.southeast.rr.com [24.93.73.74] 5 3 ms 4 ms 3 ms ten2-0-0.chrlncsa-p-rtr01.southeast.rr.com [24.93.73.33] 6 3 ms 4 ms 20 ms ge-2-1-0.chrlncpop-rtr1.southeast.rr.com [24.93.73.58] 7 22 ms 9 ms 12 ms ae-3-0.cr0.atl20.tbone.rr.com [66.109.6.82] 8 8 ms 8 ms 9 ms ae-0-0.pr0.atl20.tbone.rr.com [66.109.6.171] 9 25 ms 25 ms 30 ms xe-7-1-0.edge4.Atlanta2.Level3.net [4.59.12.29] 10 9 ms 8 ms 8 ms ae-21-52.car1.Atlanta1.Level3.net [4.68.103.34] 11 8 ms 9 ms 8 ms vnsc-bak.sys.gtei.net [4.2.2.2] Trace complete. C:\> Looking at the ping times above, you see that hops 7 (a Time Warner device) & 9 (a Level 3 device) have higher response times. While in this example they are still well within acceptable limits, you're looking for a hop that is going to have REALLY big numbers, probably 3000 ms or more just for that one device. This would indicate a software, hardware, or configuration problem with that particular device, or simply more data than it can handle. Once you know the device, you can contact that particular provider and point it out to them. They SHOULD know about it by now if this has been going on for 3 weeks, but then again, stranger things have happened... HTH. Let us know what you find. Jonathan L.

Do you use a variety of endpoints ? What is your MTU ? Erik Goldoff IT Consultant Systems, Networks, & Security ' Security is an ongoing process, not a one time event ! ' From: Evan Brastow [mailto:[email protected]] Sent: Thursday, November 11, 2010 6:48 PM To: NT System Admin Issues Subject: Loooooong ping times Hi peoples, I have a weird issue, and I've had it for about 3 weeks (don't worry, it's work related!) Our Internet connection has been really slow. Web sites time out half the time, and just load really slowly other times. Our connection is a Comcast connection, and I called then to see if they could test the speed. They did, and it seemed okay to them, but then said that we had an old cable modem. They replaced the modem, but it made no difference. When I use speedtest.net, or speedtest.comcast.net. I usually get good throughput times (36 Mbps up, 7 Mbps down) but I get a ping time that is almost ALWAYS 3146 ms. Sometimes it's 3147, sometimes it's 3145, but it's 3146 90% of the time. Weird, huh?! So, I went to my SonicWALL and unchecked the check box that was set to enable the DHCP server. I thought maybe having two DHCP servers (the SonicWALL and my own internal DHCP server) was an issue. I don't even know why the DHCP server was enabled on the firewall. So I disabled that, and I'm still having the same issue - very long ping times, though now it's somewhat intermittent. At times, I get a ping time of 72ms, and the others, it's right back to 3146, So my question is, where should I be looking to fix this? Essentially, I have two DNS servers, one DHCP server (not including the SonicWALL,) Then I have our firewall, and then the cable modem. That's it. Help? I have no clue how to troubleshoot this.
