 |
|
I just installed NM and I am impressed. The WiFi started OK and it got my VPN working when I had failed using scripts. However, it fails to start my 3G modem. I get:

Apr 14 20:21:07 topaz NetworkManager[5791]: nm_system_iface_flush_addresses: assertion `ifindex >
0' failed
which looks like it is not getting very far. This modem *does* work fine if I start it with scripts. It would just be nice to control everything from the same widget.
TIA

does your modem, by any chance, require loading firmware within the scripts? Is the firmware loading process properly configured in udev?

Yes, that's all done. Dan Williams on the NetworkManager list told me to turn on modem-manager tracing and that revealed the phone number was getting mangled. It looks like there might be a small bug in knetworkmanagement. I will know more when I get home tonight and test.

The "bug" was mine.  I changed the number dialled from "*99#" to "*99***1#" like I had used in my scripts. NM works out what is actually required and modifies the number, so I ended up with "*99***1***1#" which doesn't work!
