That makes no sense unless you have it configured so that it is *not* forced to only use 3G. If you set it up using the Vodaphone software on Windoof - that's what will have happened. Install cmgt # apt-get install cmgt Find out what devices your modem uses.. eg.:- $ dmesg | grep GSM | more [ 10.976642] USB Serial support registered for GSM modem (1-port) [ 10.978427] option 1-2.4:1.0: GSM modem (1-port) converter detected [ 10.985660] usb 1-2.4: GSM modem (1-port) converter now attached to ttyUSB0 [ 10.985877] option 1-2.4:1.1: GSM modem (1-port) converter detected [ 10.991062] usb 1-2.4: GSM modem (1-port) converter now attached to ttyUSB1 [ 10.991325] option 1-2.4:1.2: GSM modem (1-port) converter detected [ 10.997840] usb 1-2.4: GSM modem (1-port) converter now attached to ttyUSB2 [ 10.998051] option: v0.7.2:USB Driver for GSM modems In this case /dev/USBtty0 - 2 are created. Now find out which one it gets network data from:- $ cat /dev/USBtty0 (nothing there so kill with Ctrl+C) ^C $ cat /dev/USBtty1 (bingo!) +ZPASR: "HSDPA" +ZPASR: "3G" <snipped> Self explanatory. Edit /usr/bin/sigmon to use that device. There's a backup in /etc/comgt # nano /usr/bin/sigmon find the line:- comgt -d /dev/ttyUSBx sig and change x to reflect the network port of your device For this example it's USBtty1 comgt -d /dev/ttyUSB1 sig save it, then, run sigmon # sigmon Use Ctrl/C to terminate monitoring Signal Quality: 24,99 Signal Quality:R: "3G" Signal Quality: 24,99 Signal Quality: 24,99 ^C "24" is the value of the relative signal strength. Give us the information on your modem and I'll tell you how to boost that signal, and force your modem to *only* use 3G. > The worst is that when the disconnects happen (which is > often) I have to plug it out and back in, as NetworkManager can't > reconnect otherwise.

The relevant lsusb would be nice. :-) Cheers -- Iceweasel/Firefox extensions for finding answers to Debian questions:- https://addons.mozilla.org/en-US/firefox/collections/Scott_Ferguson/debian/ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
