[Speed Problem] At Wit's End in AT&T Southeast http://www.dslreports.com/forum/r20473101 en Sun, 23 Nov 2008 06:30:21 EDT Sun, 23 Nov 2008 06:30:21 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20490220 FastAttack : ok lets get to the nitty gritty here then

1) What is your current DSL setup ( home run or filters around the house
2) DSL modem , which one are you running and what are you line stats behind the modem doing the pppoe not the secondary router
3) what os are you running on the test machine
4) have you done arp flush and your hosts file is empty
5) are you running any sort of software firewall including windows firewalls.
6) go to the command prompt and enter nestat and post your results here.

and lets go from there :)]]> http://www.dslreports.com/forum/remark,20490220 Thu, 15 May 2008 22:20:16 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20490138 MarcWash : The issue with the first line of the tracert being incorrect was a bug in the router firmware. I upgraded to the latest version and it now correctly displays 192.168.1.1 in the first line. Ping times remain the same, however; the router is not the cause of the speed problem since they persist even when the router is out of the picture entirely.]]> http://www.dslreports.com/forum/remark,20490138 Thu, 15 May 2008 22:07:27 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20484252 MarcWash : >is there any p2p / downloads happening on the background

I've thought of that, but it's not likely. Any single machine I attach directly to the modem experiences the same speeds, and I have several to choose from, not to mention the Bellsouth technician's PC as well as my laptop from work. They would all need to be infected with something. ]]> http://www.dslreports.com/forum/remark,20484252 Wed, 14 May 2008 22:06:06 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20480389 FAQFixer :
said by ropeguru See Profile :

Just thought off the top of my head, but could it be either an issue at the DSLAM/RT with the backhaul feed or even something with the DSLAM/RT port?
Not really. This is a problem on the customer's PC.]]> http://www.dslreports.com/forum/remark,20480389 Wed, 14 May 2008 10:20:53 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20479799 ropeguru : That was my next thought giving that everything else looked good in what he has posted.

I kind of doubt it as I would have thought that AT&T would have had more complaints. Was just a thought.]]> http://www.dslreports.com/forum/remark,20479799 Wed, 14 May 2008 07:28:45 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20478509 FastAttack : those high ping rates at the first hop can only be tracked down to the computer sending and recieving at max capacity.

is there any p2p / downloads happening on the background and or did you recently do a virus/trojan check on all the machines on your network?

i've seen those types of traceroutes before when you maxed out the connection on the upload side mostly.]]> http://www.dslreports.com/forum/remark,20478509 Tue, 13 May 2008 22:31:01 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20477630 Airwolf7 : I don't know which modem you have, but if it is from BellSouth then somewhere within the GUI it has a Diagnostics Page. Run a Traceroute from this Diagnostics Page then copy and paste the results into a reply.


I don't really know why I want you to do this other than the fact that I'm just curious.

Run Traceroute from modem's Diagnostics Page.

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?

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. ]]> http://www.dslreports.com/forum/remark,20476001 Tue, 13 May 2008 14:42:42 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20475792 MarcWash : 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. ]]> http://www.dslreports.com/forum/remark,20475792 Tue, 13 May 2008 14:04:15 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20475425 ropeguru : 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?]]> http://www.dslreports.com/forum/remark,20475425 Tue, 13 May 2008 12:56:07 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20475249 MarcWash : 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.]]> http://www.dslreports.com/forum/remark,20475249 Tue, 13 May 2008 12:21:22 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20474333 ropeguru : Yup... Was supposed to be 192.168.1.1 or 192.168.1.254...]]> http://www.dslreports.com/forum/remark,20474333 Tue, 13 May 2008 09:16:39 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20474330 Airwolf7 : 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.]]> http://www.dslreports.com/forum/remark,20474330 Tue, 13 May 2008 09:15:43 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20474315 graysonf : 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.]]> http://www.dslreports.com/forum/remark,20474315 Tue, 13 May 2008 09:12:56 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20474259 ropeguru : 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 See Profile 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]]> http://www.dslreports.com/forum/remark,20474259 Tue, 13 May 2008 08:53:57 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20473314 Airwolf7 : Why is your trace route starting at Google and ending at Google?]]> http://www.dslreports.com/forum/remark,20473314 Tue, 13 May 2008 00:08:51 EDT Re: [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20473226 graysonf : The first hop is the ingress/aggregation router at your ISP's data center. That can be a long way away.]]> http://www.dslreports.com/forum/remark,20473226 Mon, 12 May 2008 23:38:46 EDT [Speed Problem] At Wit's End http://www.dslreports.com/forum/remark,20473101 MarcWash : Ever since fall of last year I've been having severe speed issues with my Bellsouth FastAccess Xtreme.

»/linequality/nil/2383943

I regularly see hop times in the >500ms range for the first hop, with extremely rare instances of perfectly normal ping times. The normal periods are short and unpredictable. I can run a speed test with Bellsouth on the phone and it will come up perfectly normal, then I run it again and my download speed is 300kbps or LESS on a 3MB service.

I have had Bellsouth send someone out to my house. He was here for half a day and supposedly fixed several things, but none of them had the slightest impact on my service. When he left, there was literally nothing else that he knew how to fix. So far I have tried three different modems and at least four computers (five counting the technician's laptop when he was here). Despite this, I have had Bellsouth tell me that this was due to spyware on my computer.

I am at my wit's end here. This has been going on for half a year, and not only do I not have the slightest idea of the cause, but apparently neither does Bellsouth. So far, all I've got is what the problem is NOT. A line issue in my house? The technician got the same results when he hooked up outside. A line issue with the underground feed coming across the street? The technician said his measurements were perfect when he tested it. Bad modem? Gone through three.

Can anyone give me suggestions on what to ask for the next time I call Bellsouth? And what exactly IS the first hop? Is it the box across the street, or is it something else further away?
