My DSL line shuts down every 3 or 4 minutes.  Very annoying.  Must reconfigure or close and wait to get back on.  Any suggestions?  ISP is no help whatsoever.

Ran a free optimization recommendation program that gave many suggestions for improving connection and speed, such as changing value for auto MTU Detection, Selective ACKS, TCP receiving, etc.  Have no idea where one can change values.  Some must be done in registry, hence need for Ipv6.exe app--but my computer will not let DOS APPS stay open!  Help!!

Oh YEAH, running Windows XP media center.

Thanks, KWhat optimisation program did you run ? ?

How is your network set up ? ? Modem and a router or just modem ? ?

How long have you had DSL and did this just start happening ? ?
I have had DSL for about five months--in combination with phone service.  It worked beautifully for several weeks, then I started experiencing problems.  Apart from several seconds of STATIC at onset, the phone works fine--though it does cut off the internet when used--something it shouldn't do.

I have a single computer with a remote modem supplied by the ISP connected via a 1394 net adapter.  I ran a free checkup with PC Pitstop which only lists recommendations, and does not repair problems unless you buy it.

The problem with not being able to open applications such as the Ipv6 has always existed.The static and dropped signal on phone activity indicate it is probably a line issue.

Did you place filters on all the phone lines in the house that were provided with the modem ? ?

Try it temporarily on another phone jack if possible to SEE if conditions improve.

PC PitStop although decent usually wants to sell you something so take their info with a grain of salt.

I am not familiar with the program you mentioned...care to elaborate on that ?I have filters on all jacks, and have disconnected and reconnected them several times.  Will try hooking up to another jack, as you suggested, but that will take some work--not a simple task.

Ipv6.exe is a Windows utility application in the System 32 folder that supposedly allows you to change values for MTU Detection (part of the PC Pitstop evaluation).  Try it on your computer.  Can you open it?  I doubleclick the icon and I see a flash of a window (looks like a DOS window)-then nothing.  Is this normal?

Anyway, I'm writing below the evaluation summary for Internet improvement:
Use HTTP1.1 on proxy                 none      1
Refresh pages auto.                    none      4
IE cache size KB                           none      81920
Max. Trans.                                  none      1492
TCP Receiving                               0            17520
Default TTL                                   none         64
Auto MTU Detection                      none           1
Black Hole Detection                     none           1
Max. Dup. ACKs                             none           2
Fast trans. & recovery support      none          1
Selective ACKs                               none           1
Max. connections                           none          6
Max. 1.0 connections                     none          6

first column is existing status, second is recommended.  Little of it means anything to me.  If you think changing any of the values might help with my disconnect problem, I'd certainly appreciate knowing how to do it.

Many thanks for your help!

Kathy

Why not run a program like TCPOptimiser to make these changes ? ?

Last i heard it was still free and it runs in Windows...
