Red Hat Bugzilla – Bug 459805
NetworkManager not working with Nokia mobile phones
Last modified: 2008-08-22 11:37:01 EDT
The latest NetworkManager has "mobile broadband". I don't know what devices this is meant to include, but I have two Nokia phones (one of them GPRS/EDGE, the other 3G) and it doesn't work with either.
Both provide a device /dev/ttyACM0 (or ttyACM1, etc) via the kernel module cdc_acm. This is a standard modem device - to connect to the Internet you just use pppd/wvdial/chat etc. (I have a friend with a Samba75 modem that requires an extra line to be sent in the chat script to select the correct APN (access point) - but with the Nokia phones, that setting is already on the phone so nothing extra is needed). I just set it up in system-config-network as a modem device and "it just works".
NetworkManager, though, doesn't appear to have any facility to use the device. When I go into "mobile broadband" and click "Add", nothing happens. If I select "controlled by NetworkManager" in system-config-network it doesn't show up anywhere. When I go online (with /sbin/ifup ppp0) NetworkManager doesn't know I'm connected. In short, NM seems to have no ability to handle this kind of device - which leads to frustration, as then Firefox, Pidgin etc. think I'm offline, etc.
There's likely to be a few hundred million or so of these phones in existence, so better NM support would be much appreciated! Thanks for the hard work.
The phone needs to be detected by HAL as a GSM or CDMA device. Please file a bug upstream on bugzilla.freedesktop.org against HAL with the output of 'lshal' and 'lsusb -v' when the phone is plugged in. When the phone is correctly tagged in HAL as a mobile broadband device, NetworkManager will recognize it and you'll be able to pick it from the menu.
