gnome ppp download speed 1.5 to 2.8 kbps

[jkohler2]

In earlier times using a 56k modem to an old serial port, the dial-up program would usually get a 30 to 40 kbps connection on good days, and 14.4 kbps on bad days.

I am trying another dialup method now. A 56k Zoom usb modem model 3095, connects to the phone line and Gnome-ppp makes a successful configuration that works.


The trouble is the download speed, from 1.5 to 2.8 kbps. I am seeing some hayes commands I don't recognize after the "atz" like atq0v1e1s0-0&c1&d2+fclass=0 and atm1L3dt*70,,nnnnnnnn(phone number)

Is the dialing string wrong? If so, can I tell GNOME PPP to change it?

How do I do that?

Thanks, in advance,

John

Connection speed is expressed in KiloBITS per second. Download speed in KiloBYTES per second. Conversion is 1 Byte = 8 Bits.

Given ideal conditions (i.e. clean phone line, fast download server, etc.) the max actual download speed should be in the vicinity of 5 KBytes/sec. This should correspond to ideal connection speeds of 45-48 kBits/sec.

I don't think it's an init string problem coz you can get connection speeds of up to 40 kbps on good days. My hunch is you have an old / noisy phone line. Maybe you can convince your telephone company to replace the line.

Same setup, different problem: The Acer 5315 laptop and zoom 3095 usb modem connect to the mlocal AT&T dial up line even though the CHAP and PAP logs indicate errors. The connection is 42 kbps, reliably. If, however,
I use another ISP phone number, with my valid ID and password, the same modem under GNOME-PPP takes the phone off-hook, detects dial tone, dials the number, but doesn't do the handshake successfully.

I don't know how to view, or print, the log of the failed connection.

Same problem as thread owner. Only getting max download speeds of 2.2kb/s. Driving me crazy.

What type of modem are you using? Is it the linuxant version?

[EXCiD3]

Zoom 3095 USB Modem...and yes apparently its the one that you have to pay for to get over 14.4kb/s :(

Any other way to get it up to speed?
