That's pretty normal for V.34 connections... As a matter of fact the Mwave
connection sound at V.34 is a lot tamer than my US-Robotics V.34 modem.
28.8Kbps connection requires VERY good telephone line quality... House wiring
and your distance from the Central Office could have a lot to with it to.
I have been able to get many 26.4K connects with the new software... I'm happy!
Here's what the README file in the MWAVE program group suggests:
If you experience difficulties connecting at a modem speed of 28.8
kbps to a particular number, or if you have trouble connecting to a
particular modem rotary, try the following.
- If the connection is not made and the speaker is OFF:
1. Disable V.42 bis and MNP 5 using AT"H%C
2. Disable V.42 (AT\N3) or MNP 1-4 (AT\N5). You could also
disable both with AT\N.
- If the connection is not made and the speaker remains on:
1. Reduce the maximum modem throughput using the AT commands
ATs28=18 (for 26400 bps), ATS28=17 (24000bps), ATS28=16
(21600 bps), or ATS28=15 (19200 bps).
2. If you've tried step 1 and it still does not connect, use
AT*TH8 to control the speed.
Once you connect using the AT*TH8 command, remember to reset
your modem using either AT&F (for factory defaults) or
AT*TH4. If you forget to reset, your next calls will transmit
at lower V.34 connection rates.
