Re: [Speed Problem] At Wit's End
Was my first thought too. The 64.233.167.99 address is in Googles set of network addresses per ARIN. The second hop showing 65.14.148.5 is in AT&T's set of network addresses per ARIN.
Looks like to me he has something wacky with routing in his router.
MarcWash  could you log into your DSL Modem and possibly pull up and post the routing table?? I almost think that you are getting some incorrect IP addressing from AT&T.
Edit: What is the ip address assigned to your computer and what is the default gateway showing on your computer? Check these first before what I asked above. Reason I am asking this is that I just took a look at someone else's traceroute in abother thread and it hit me that the first hop should be the IP of your modem if it is in router mode and not bridged. You should have something like 192.168.1.1 or 192.168.1.254 as the first hop. I am wondering if your DHCP pool is incorrectly configured.
Edit for typo in IP address |

Fort Lauderdale, FL | Not sure about 192.157.1.1 being a possibility. That's in a block belonging to RIPE (Europe). There are some problems with the block, but I don't see it being made available to ARIN. |

Franklin, KY | I'm pretty sure that 192.157.1.1 is a typo for 192.168.1.1 because the 5 key and the 7 key is shifted one key over to the left of the 6 key and the 8 key. |

My default gateway is 192.168.1.1 (my linksys router)
and the IP is 192.168.1.102
Normally (and currently) I have a linksys router sharing my DSL among 4 computers. Obviously, I disconnect it and plug one machine directly into the DSL modem before I call Bellsouth, and during the technician visit months ago. I get the exact same results regardless of whether the Linksys router is being used.
I ran a tracert right now and got pings of ~20ms for the first hop. I wish it would stay that way, but I know that it won't. When I get home, I'll get the routing tables off the modem. |

| Is the first hop still coming back the same as the one in your original traceroute??
When you were directly connected to the DSL modem as you were in the first traceroute, was the modem in bridged mode and your computer doing the PPPoE or was the modem in NAT mode and it doing the PPPoE. I am trying to figure out if maybe AT&T has a bad address pool in the mix. Also, do you have the static IP option? |

| Yes, the first line of the tracert to google.com is still something at google.com. Now that someone has pointed out the obvious, it DOES seem kinda strange that that isn't my gateway.
Note: the screencap I posted is from the same configuration, through the linksys router. Nothing changed from the >600ms trace to the 20ms trace... same machine, same setup. This is consistent with the directly-to-modem performance. |

| That really is weird. Typically with all routers like the linksys, you will get a response from the internal IP address, ie. 192.168.1.1, and not the external. Weird indeed.
Maybe try ordering the static ip option and see if the issue goes away. |

| I'm attaching two images. The first is a TRACERT and IPCONFIG done with a laptop connected directly to the DSL modem. The second is the only routing information I could find in the modem. The time, the first line of the TRACERT does contain the address of the modem as expected. The ping times are still horrible, as expected. At the very top of that image you can see the last few lines of a previous tracert done with the computer connected through the linksys router. The first line is not visible, but it contained the google address just as the previous screenshot. The ping times are horrible there as well.
Are there any other tools that I can use to help troubleshoot this? |

Run Traceroute from modem's Diagnostics Page. |
I don't really know why I want you to do this other than the fact that I'm just curious. |
