Analog Modem Tweak:

Open Regedit (click on start - execute - enter "regedit"-click ok)
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem\000
(it could be 001, depends of your modem installation)

At right, find the binary value "Properties". Double click on it. Now you will see numbers and other characters. Check for "C2 01" at the second column, at the right of "0018". Just replace "C2" by "10"(ten) and "01" by "0E". Don't modify any other value. Click Ok and close regedit. Restart your computer.

Now, go in the control panel. Double click on Modems. Click on the properties button. Now check for Maximum Speed: There are 3 new speeds available!! These speeds can really work with your modem, it's just the maximum speeds for your port.

Note: your computer must have a 25mhz processor minimum to use this tip.

Try all of the 3 speeds to look which is the best for your configuration. Some speeds may not be supported, in this case try a lower speed.

For the next tweek open regedit again and go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem\CDFS\. Depending on your version of windows you will either have to enter the value in either decimal or hexadecimal.You can increase the CacheSize from the default of decimal 619 (hex 26B) to 2476 (9AC). To increase the buffer size from the default quad-speed support, change the Prefetch line from its default of 228 decimal (hex E4) to decimal 1792 (hex 700). This tweek tells windows to optimize for a 32 speed drive instead of a 4 speed cd-rom.

This tip works on ALL Windows 95/98/ME and NT4/2000 systems with MS Internet Explorer 4/5/6 installed.
This Registry tip speeds up internet/remote (using Windows Explorer and/or Internet Explorer) browsing process considerably on most MS Windows 32-bit machines connected to a network and/or remote computer(s).
This actually fixes a BUG in MS Windows OSes that scan shared (remote) folders/files across the network for Scheduled Tasks, and can add a delay as long as 30 seconds (!), because it uses extra time to search the remote computer(s).
To do this, open Regedit (Win95/98/ME) or Regedt32 (WinNT4/2000) and go to:


HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\NameSpace

Highlight this value:

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

and delete it: right-click on it -> select Delete -> click OK.Remove Dummy Installed Files in your Add/Remove Programs:Sometimes, even after program are uninstalled, or due to the files being deleted instead of a uninstalled, the entry in the Add/Remove Programs list does not get deleted. To remove it form the list:
1. Start the Registry Editor (Run > regedit.exe).
2. Open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion\Uninstall.

Here are three easy ways to improve your dial-up modem performance:

1 ) You can't assume that just because you connected at a speed like 48.3KBps that you will stay there. Today's modems automatically fall back to a lower speed if the line noise is too high to maintain a faster connection, but sometimes they fall back too soon or too far.

Here's how to do it:

Click Start the button.
Select Settings.
Click Control Panel.
Double-click on the Modems icon.
Select your modem.
Click the Properties button.
Click the Connections tab.
Click the Advanced button.
In the "Extra settings" field, type S36=7
Click OK to save your settings.

This will force your modem to try to stay connected at high speeds in two different ways before dropping back to an asynchronous mode with auto speed buffering.

2 ) With Windows 95 and 98, there is an easy way to increase the speed at which you connect to your ISP. To do this:

Click the Start button.
Select Settings.
Click Control Panel.
Double-click on the Modems icon.
Select your modem.
Click the Properties button.
Click the Connections tab.
Click the Advanced button.
In the "Extra settings" field, type S11=50
Click OK to save your settings.

3 ) If you are experiencing a lot of modem timeouts with your system, you can change the SLOWNET value in the Registry

Click Start the button.
Select Run.
Type "regedit".
Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0000 (0001 etc).
Change the SLOWNET value from 01 to 00.

If you suffer from random disconnections using your modem, you can improve reliability by using the following modem init strings.
Place the following values into your modem init string:

&U15&N15

This eliminates retrains

You might also try:

S10=30 or even S10=50

(all modems) as this gives protection against line drops due to short noise bursts or carrier interruptions.
