I've been used 11.04, now 12.04 LTS, and if there is solution, I don't want to upgrade from that LTS.

The first problem is, that the network-manager/networking behaves wrong:

  • when I'm on battery, the WiFi connects (the mobile broadband also), but no network can be accessed, like when something timing out. If I connect the AC charger, it immediately starts working.
  • usually just lists the options: enable network, enable wireless network, enable mobile broadband, edit networks & network information, there are no lists of available networks, etc...

Bluetooth:

  • The Bluetooth is always turns on on start up, but when I turn it off on another 12.04 LTS, it remembers, and doesn't turn on on start up.

Conclusion: this laptop is no longer mobile, it requires AC charger to connect to networks.


What I have tried to solve the main problem?

  • Upgrade the network-manager, to the latest daily PPA version: 0.9.6.0~git201208071622.5714-0~pkg562~precise1
  • replace wireless driver with b43, but is was not supported (How do I get a Broadcom BCM4313 wireless card working?)
  • upgrade the BIOS. Now I have version A05, the latest is A06, but I couldn't because I haven't found the HDR file in Dell's repos (there is no *system_bios_ven_0x1028_dev_0x0470_version_A06* dir), and I could't generate if from the Windows executable (wine /writehdrfile /nopause now doesn't work) - original tutorial is here
  • install some Dell software/firmware:
ii  dell-dup                                      1.1.3-0ubuntu2                                        A firmware-tools plugin for Dell DUP images
ii  firmware-addon-dell                           2.2.9-0ubuntu1                                        A firmware-tools plugin to handle BIOS/Firmware for Dell systems

The WiFi problem:

  • when I'm on battery, the WiFi connects (the mobile broadband also), but no network can be accessed, like when something timing out. If I
    connect the AC charger, it immediately starts working.

is solved by installing broadcom-sta-common (on 12.04.2 LTS), then restart:

sudo apt-get update
sudo apt-get -y install broadcom-sta-common
sudo reboot

My device is:

$ lspci | grep BCM

03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)




The network manager pop-up problem is still exists, tried with the current stable and the testing releases from that PPA with no success...
