Bug Description
Binary package hint: network-manager
I have an Asus laptop with integrated 3G modem, which works perfectly fine in Windows7.
I am running Ubuntu 11.04 Alpha 1 64bit fully updated with kernel 2.6.37-12-generic.
network-manager version: 0.8.3+git.
At boot NetworkManager disables WWAN by radio killswitch unprompted and right after enabling it.
Attached there is a copy of the portion of syslog.
It is not possible to enable the hardware radio once the system has booted and therefore establishing a connection with said modem is not available, or it is available but in fact it is not possible because of no radio, no signal, no registration to network etc.
The hardware is Haewei E620 according to lsusb, and Haewei EM770 according to AT+GMM
Acpi4asus has implemented a patch for the radio issue of the aforementioned hardware and it was merged into mainline:

Before trying to connect the mobile session, can you please check the following two items?
- Verify that /var/lib/ NetworkManager/ NetworkManager. state does not show "false" somewhere.
- Verify that the output of "rfkill list" does not list items as blocked ('yes' at the end of a line)
Thanks in advance!
