No, turning it off using the /sys/devices/... switch works fine for me. The LED goes off, signalling that the modem is not powered. It can be powered on again using the switch and can then be used to connect.
Yes, there is a physical button to completely disable it. But: This button disables ALL wireless communications: WLAN, bluetooth, WWAN. Switching the physical button again, turns ON WLAN and bluetooth again, and is therefore useful to "switch the modem off" to save power. But unfortunately, networkmanager seems to have problems (sometimes) using the interface THEN again. I only noticed this because I tried today, this used to work some time ago o.O See here: http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module#Turning_the_card_off -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/556323 Title: Disable mobile broadband has no effect on most modems Status in Network Manager GNOME Applet: Fix Released Status in “network-manager-applet” package in Ubuntu: Triaged Bug description: Hello to all of you. I am using a complete up to date Lucid on my Thinkpad T500 with integrated mobile broadband modem. The modem itself can be used without any problems. The only thing is, that the "Disable mobile broadband" switch in the right click menu of network-manager-applet (on gnome) takes absolutely no effect. I can connect with the modem when mobile broadband should be disabled, and furthermore, when i disable via the switch, the device is not powered down. This is not very nice on a laptop where energy is a rare resource. I attached the corresponding lsusb -vvv part This is what syslog shows when first clicking on enable mobile broadband: Apr 6 11:17:15 localhost modem-manager: (ttyACM0) opening serial device... Apr 6 11:17:15 localhost modem-manager: Modem /org/freedesktop/ModemManager/Modems/0: state changed (disabled -> enabling) Apr 6 11:17:15 localhost modem-manager: Got failure code 100: Unknown error Apr 6 11:17:15 localhost modem-manager: Invalid error code Apr 6 11:17:15 localhost modem-manager: Got failure code 100: Unknown error Apr 6 11:17:15 localhost modem-manager: Modem /org/freedesktop/ModemManager/Modems/0: state changed (enabling -> enabled) This powers up the device. And then when clicking on disable, the following occurs: Apr 6 11:17:26 localhost modem-manager: Modem /org/freedesktop/ModemManager/Modems/0: state changed (enabled -> disabling) Apr 6 11:17:26 localhost modem-manager: (ttyACM0) closing serial device... Apr 6 11:17:26 localhost modem-manager: Modem /org/freedesktop/ModemManager/Modems/0: state changed (disabling -> disabled) But the device isn't powered down. I can choose to connect both when the device is up and when the device isn't running yet (choosing then activates the device) To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-applet/+bug/556323/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
