dsl problems - need diagnostic help!

The last 4 days my dsl connection has been DOG slow, and I'm beginning to go insane.

I'm gonna call pacbell on Tuesday, but I want to have as much data lined up as I can.

Does anyone know if there are any tools to help trackdown where the bottleneck might be occuring?

Any tips appreciated!

thanks

What OS are you using? There's a command "tracert a.b.c.d" where a.b.c.d is an IP. Tracert will show you times to get from your computer to each hop to the a.b.c.d destination and will often pinpoint the bottleneck. I don't think tracert comes with Win98 though, at least the last time I tried to run it under 98, it wasn't found. If that's a problem maybe someone here could tell you where to get it or you could do a search on the web.

Hmm, it wasn't my computer that I tried it on so the company must have removed it. I use 98 for only one thing -- a home theater computer -- and I don't trace IP's on it.

Ok... found one for the mac.

Here's what I get to dvdtalk.com. Does anyone know how to read these numbers? Does this look as slow on "paper" as it does to my eyes when connecting to dvdtalk.com (or anywhere else, for that matter)

Interesting , i tried it several more times, and oftentimes it just sits there at sprintlink.net for several seconds (10 or more)...

I wonder if there's some huge router dead somewhere.

They look just like what I'm used to about 70 miles north of you and my response is fine. Times under 100 ms are fine, especially since they're going all the way across the country and halfway back.

Well.. I took a guess at what might be wrong, and found it.

PacBell gives a primary and secondary DNS ip address for the tcp config file. On a lark I switched them so that the secondary is now listed first... and shazam, everything's lightning fast again.

I've sent mail to pacbell tech support about this. How much you wanna bet I don't get a response?



thanks for all the help!

Which ones did you have for primary/secondary? I use a.b.28.d (primary) and a.b.31.d (secondary) and they work pretty well.

Interesting... I had it the same as you: 28 primary, 31 secondary - but it was horribly slow.

Switching them fixes it.

I'm in Santa Cruz, where are you?

Southern Marin. Also interesting that I have one extra hop than you. But everything goes through San Jose.

Well, we're what... 80 miles from each other? I wonder if the two different DNS servers are in different locations. Hmm... wonder how one would find that out?

interesting... here's the traceroutes to the two pacbell dns ips. Looks like 28 is in San Francisco, and 31 is in Sacremento (just guessing from the letters in the ip name lookup). So I guess something's honked between Santa Cruz and the San Francisco DNS server, but I'm still able to get to Sacremento.

might consider running a check at dslreports.com

it tests your connection and system and tells you which settings should be altered..

might be worth a shot

You might try 29 as the secondary (or primary). Interesting that you had 31 as I do. I tend to make a secondary geographically different than my primary. Old earthquake-paranoia habits...

And stop giving out your IP!

Only IIS 5 (and maybe 4 for CodeRed I?). Due to a buffer overflow in an indexing service. Specifically MS.

yea.. i knew as far as MS went.. it was only a problem for IIS users

but Im not really familiar with macos, so I figured I would ask

since that could have been a possible cause

That wasn't my ip, just some intermediate pacbell dsl ip.

Just the same, I'm not very paranoid about it. I run firewall software, and I'm (as you know) on a mac - the potential for a hacker to get in and screw around is pretty low for me (hmm.. sounds like famous last words!)

BTW, looks like 29 is in LA... about 3 times as many hops as to get to as sacremento.

30, however, is only 4 hops... appears to be in San Diego. I might give that a try.

That "intermediate pacbell dsl ip" is your dsl router. You want me to reconfigure it for you?

Pretty impressive, from your original question to this point...
