pppd no CHAP response when using NM
Hi,
I'm trying to connect with a GSM USB modem ZTE MF-100 (USB ID 19d2:0039)
to a mobile broadband network (German Congstar = network of German
Telecom) with debian testing.
Using KDE NetworkManager, my problem is that pppd doesn't answer the CHAP
challenge and runs into a timeout (see log file). In NM, the hooks at
"Authentication" and at "CHAP" may be checked or not, doesn't matter. If
they are set, a hook at "EAP" always re-appears even when it was
unchecked.
Using wvdial, the connection is established correctly when "stupid mode =
1" is set.
Maybe this is the root cause but I'm not sure. Is there a way to get more
debugging (parameters of pppd...) than shown in the logfiles below? How
can "stupid mode = 1" be configured in NM (or any other parameters which
are not accessible by the GUI of the NM)? Does it read a config file
similar like wvdial.conf, where is it placed?
According to this page, NM works for others with this provider and this
HW, so I assume it's not big issue:

Anybody some hints?
greetings Stefan
