Dial-Up vs. Trumpet: very low transfer speed

I used to have a 486 with Win 3.11 and a 14400 USR modem. To connect with the outside world I used Trumpet Winsock software which I got from my University. It worked fine. Then I made a massive upgrade to a Pentium and installed Win95+. I kept the old dial-up software (Trumpet) but also
installed a new package called Inet 2.0 (again provided by the University) which worked using Win95 Dialup. Although I was told that Trumpet was not supposed to work under Win95 it still worked great. However, when I started using Inet with Dial-Up I found that although dialup says that it connects at 12000, it works painfully slowly when I use Netscape or when I download files to my comp using FTP. Transfer speeds are around 500 Bps. I played with the baud rate setting, network parameters and other stuff and reinstalled both Dial-Up and Inet but nothing seems to help. BTW, both "software compression" and "IP header compression" were checked but that did not change anything.

Try to enable the "software compression" in server type,
turn on "Use IP Header compression" in Server type/TCP/IP settings.

Both "software compression" in server type and "Use IP Header compression" in Server type/TCP/IP settings were checked before. Are there any other things I could do?

Get rid of trumpet alltogether. Win95 works at it's best with it's own Dial-up Networking. Make sure you have the "microsoft protocol tcp/ip" selected.

I need clarification from infoghost. What if I don't use Trumpet without deliting it from my computer? Should this affect performance of Dial-Up? What I don't understand is how Trumpet can cause any changes if I, say, use Trumpet today and Dial-Up tomorrow. Do they both access the same special files of some sort so that if Trumpet is EVER used the files are changed and Dial-Up experiences problems? Thanks.

I havent so far (Ive set up >200 Dialups) seen or had any need to use anything but win95's built in dialup. Its easy to use, its fast, its supported by a BIG company and its free.

Reply to nylja:

Do you mean Dial Up with nothing else like Inet or or Dial Up with whatever the necessary additional software there is? If it is the former then cen you tell me if there are built in Telnet and FTP capabilities in Dial Up. If it is the latter then I just want to clarify that the reason that I keep using Trumpet is not because I have any sentimental feelings about old software but because Dial Up is not functioning properly.

Thanks for your comment, though.

1. Disable compression on your modem
2. Under the 386Enh section put:
COMxBuffer=1024
(where x is the Comport #); you can disable error correction by un-checking that box under the modem settings and adding the string:
AT%C0 to the extra settings area in the modem settings.
To improve your ports speed, go to “ Control Panel | System | Communication Ports , then double-click the port your modems in, then click the Properties tab and set the Port Speed to 921600 BPS;

Try these
registry:
\ HKEY_LOCALMACHINE \ System \ CurrentControlSet \ Services \ VxD \ MSTCP \ DefaultRcvWindow -> 64000 instead of 4*(MTU+4)
\ HKEY_LOCALMACHINE \ System \ CurrentControlSet \ Services \ VxD \ NWLink \ Ndi \ params \ maxsockets \max -> 1020 instead of 255
Use IP header compression with it if you use a PPP-server.

If all this fails your new modem might not be as good as you old one. Also try changing the modem type from your modem specific to a standard win95 type driver in the modem control panel.

Thanks!

After I changed Port Speed it started transfering with speed of about 1.34 KBps which is, I guess, good enough for a 14400 modem.  Anyway, I want to ask you what 386Enh in Win 95 is.

Thanks again
