Comment 20 for bug 673459

i need help on the following to use the debugging network manager guide -
i am supposed to run " sudo modprobe -r DRIVER" but i dont know what the driver is. "sudo modprobe -r" returned a lot of options, which i could not understand.
in the paragraph on debugging 3G, i need to run "$ /lib/udev/nm-modem-probe --verbose --export /sys/class/tty/ttyUSB" or "$ /lib/udev/nm-modem-probe --verbose --export /sys/class/tty/ttyACM" , both return "command not found".
other things i tried are - i inserted the 3G sim to my mobile (nokia E62) to check signals and signals are quite fine.
i added the daily update ppa from 'network manager' page (https://launchpad.net/~network-manager/+archive/trunk); it did not make any difference!
another thing i have noticed is, i also have a wireless router connected to an adsl modem ( bsnl broadband) connects through 'auto eth0', which of course is the default connection. when i have 'auto eth0' active and connect the 3G modem, the network manager detects it and connects but i cant use that connection. the moment i disconnect 'auto eth0' the 3G connection also drops.

plese let me know how to find out what driver is installed and i will post the result of "sudo modprob -r DRIVER".
thanks a lot
