ubuntu 11.04 nokia n900 modem networkmanager

Hi there!

Youre wondering why you cant use your n900 in ubuntu 11.04 as modem?

Here is a quick and dirty fix to get GSM only connection:

rmmod cdc_acm
modprobe cdc_acm

or you can use wvdial; here my config:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","business.gprsinternet"
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Phone = *99***1#
Password = t-mobile
Username = tm

Have fun!
