{*} The Problem:
-Win98 Gives A "Modem Time Out" Error And Stops Downloading.
---------------------------
{*} Conditions:
-This Usually Happens With Large Files Which Also Means A Loss Of Time In Additon To The File.
-When It Happens, I Still Stay Connected To The ISP, The File DownLoad Just Quits And I Them Get The Dreaded Error.
---------------------------
{*} Previous Actions Taken:
-(A) The Error Condition Happens When The Only Task Going On Is To Download.
-(B) I Have Tried To Download Late A Night When The Servers Should Not Be As Busy But I Still Run Into The Same Hassle.
-(C) I Have Disabled Timed-Auto Disconnect:
         "Disconnect if Idle For 'x' Mins."
This Is Related To Auto Disconnect Of The ISP Not The Modem But It Was One Of The Earlier Problems.
---------------------------
{*} Questions:
Q1 -Is The "Timed Out Disconnect" Related In A Delay From The DownLoad Site (Similar To A Printer Time-Out) ?
Q2 -If So, Where Can I Adjust This Value On My System To A
Higher Value ?
---------------------------
{*} The System:
  (1) Modem --- US-Robotics External Sportster 33.6
  (2) CPU ----- AMD K6-233
  (3) OS ------ Win98
---------------------------
{*} Help !!
-Im Sure This Is A Common Problem.
-Any Suggestions ??

Do You Know the 4 Main Threat Actor Types?

Do you know the main threat actor types? Most attackers fall into one of four categories, each with their own favored tactics, techniques, and procedures.

There are four network settings that can be configured so when dialing to an ISP, you should get somewhat greater throughput.
They are the MaxMTU, MaxMSS and DefaultRcvWindow, and DefaultTTL

MaxMTU and MaxMSS

   1.Start REGEDIT
   2.Go to Hkey_Local_Machine / System / CurrentControlset / Services / Class / netTrans / 000n
     (where n is your particular network adapter binding.)
   3.Right click on the right panel
   4.Select New / String Value
   5.Type in MaxMTU
   6.Double click on it and enter then the number you want. The usual change is to 576
   7.Similarly, you can add MaxMSS and give it a value of 536

DefaultRcvWindows and DefaultTTL

   1.Start REGEDIT
   2.Go to HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ MSTCP
   3.Add a new string DefaultRcvWindow and give it a value of 2144
   4.Add a new string DefaultTTL and give it a value of 60-64
===========
My best advice is to spend $10.00 and get TweakDun. It's made fore just such problems.
I think you can try it free.

Thank You Smeebud For Your Answer.

-You Get The 50 Points.
-Your Answer Was A Lot Of Help In That It Help Me Know That I
 Was Already On The Right Trail.  
-I Had Alread Downloaded The ShareWare Version Of The Utility  
 Which You Suggested: "TweakDun"

-I Can Now Download 8+ Mb Files @ 33.6 Without A Hassle !!
-It Took A While Of Getting Everything "Zeroed In".
 (1} -I Flashed My MB With The Latest BIOS
 (2) -I Flashed My USR Modem With The Latest BIOS
 (3) -I Used "NetLightening" To Tweak The System.
 (4) -I Use "DUNMon" To Monitor The Dial-Up Network Status.
