seems the WWAN (3G module) is not switched by the hardware switch in my Compaq 6910p under Ubuntu 11.10
In Windows I need to run some tool that is branded by Vodafone, in ubuntu now there is rfkill.
andreasr@komm-pack:/sys/class/rfkill$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
3: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: hp-wwan: Wireless WAN
Soft blocked: yes < ----------
Hard blocked: no
so we do:
andreasr@komm-pack:/sys/class/rfkill$ sudo rfkill unblock 4
result:
andreasr@komm-pack:/sys/class/rfkill$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN

3: hp-bluetooth: Bluetooth

4: hp-wwan: Wireless WAN

Hard blocked: no
andreasr@komm-pack:/sys/class/rfkill$
disable again by using "rfkill block"
