How do I activate the WWAN connection on Dell Inspiron 910 netbook?

By Tobias

I have a netbook with built-in sim card slot (Dell Inspiron 910) and Ubuntu 12.04. Now I got me a prepaid sim to go online during vacations.

I had a look at http://wiki.ubuntuusers.de/rfkill and tried several things. First of all, rfkill list:


0: phy0: Wireless LAN
        Soft blocked: No
        Hard blocked: No
1: brcmul-0: Wireless LAN
        Soft blocked: No
        Hard blocked: No
2: compal-wifi: Wireless LAN
        Soft blocked: No
        Hard blocked: No
3: compal-bluetooth: Bluetooth
        Soft blocked: No
        Hard blocked: No
4: hcio: Bluetooth
        Soft blocked: No
        Hard blocked: No

Apparently, there is no Wireless WAN. I can imagine I should block all unused devices.

lsmod | egrep '_acpi|_bluetooth|intel_oaktrail|_laptop|_rfkill|_wmi'

gives me:

dell_laptop    17767  0
compal_laptop  19315  0
dcdbas         14098  1 dell_laptop

(Whatever that means; according to modinfo dell_laptop, dell_laptop depends on dcdbas).

Finally, there must be a serious problem, because

dmesg | egrep 'radio|kill|switch'

gives me a line:

[  17.743882] dell_laptop: Blacklisted hardware detected - not enabling rfkill

How can I find out more about my “blacklisted hardware” and how to activate it?
