Kinda confused..

[Mgork]

Well lately (these past 2 weeks) I have been experiancing a strange phenomenon, every night at about 10 PM est I will get this EXTREMELY terrible lag, and when I do ping tests it will say I'm 600+ and I called Sprint DSL, they said they cant see anything wrong so I've tried everything and it seems that if I turn my modem off and restart it works perfectly, but that does get pretty annoying to do it 3 times a night. My question was, what could be causing it to do that.

that also leads me to another question, back in Jan I called Sprint about their less than acceptable latency and bandwidth rates for me and I talked to a man that said he would set the "latency switch?" down to a better level, which he did because it instantly dropped 60 ms off my ping time, well now when I get my SUPER computer built I get it connected and turns out they put it back UP!, I've been complaining and they won't seem to help.
atm i am capped at 1.5 megs but some sites say I'm only (600K) and I ping terribly to most servers. Any ideas whether I should maybe get Comcast@home or wait this out and see if anything can be done (sprint obviously won't take the blame for any of this either.) Any comments or ideas are GREATLY appreciated, thx

I'm not sure if this is it, but with some DSL networks (Covad ADSL for example) latency can be adjusted indirectly. In other words, it's not called a "latency switch", it's an adjustement for something else which can yield lower latency, however, over adjusting can cause loss of sync. If Sprint feel's your line isn't capable of handling the adjustment, they may have set it back. With Covad you have to be fiarly close to the CO, not sure about Sprint. When I had Earthlink/Covad DSL, I also had Covad make the change on the DSLAM and it greatly decreased my latency by about 40ms, if my memory serves me correctly. However, it had to be changed back because it caused sync issues.

As for performance, it's dependent on line quality, distance from CO, the ISP's network/backbone, the server's network/backbone, etc. Try downloading from a fast corportate server in your region. Also try the test at dslreports.com.

Finally, how far are you from your CO? And please conduct some traceroutes during high latency periods and post your results here. You may want to post in the Sprint forum at dslreports.com.

Conducting Traceroutes
Start | Run | command [hit OK] | tracert x >c:/trace.txt [hit ENTER]
x = IP or domain. For example, www.yahoo.com or 216.115.102.75, which resolves to www.yahoo.com (http://www.yahoo.com).
When finished, browse your C drive for a file called trace.txt. NOTE: Conducting another traceroute with the same output file name will overwrite the previous one.
Windows 2000/XP users: Substitute cmd for command.

mgork, try taking the tweaks off your system, i had kinda the same problem and i reformatted the hd and didn't add the tweaks and now im zooming everywhere. just a thought

Mgork, I found out what the "latcency switch" is. It's called interleaving and is set on the DSLAM. Interleaving is an extra level of error correction at the cost of higher latency. Again, if your line is clean and your relatively close to your CO, you should be able to run with this off (fast path) without any packet loss or sync problems.

Who do you ask for or what do you say u want, when u are trying to get DSLAM settings changed?

They dont just change stuff like that for everyone do they?
