    Wired connection with 12.04 and Dell 1545

    I know there's a fair bit of info on this problem and I think I'm part way to solving it but I still can't get a stable wired internet connection on a Dell 1545 laptop on which I've installed Ubuntu 12.04.

    It is equipped with:-
    Broadcom BCM4312 802.11b/g LP-PHY

    Marvell 88E8040 PCI-E [11ab:4354] rev3

    I've installed (I hope) the Marvell Kernel 2.6X Linux driver package and I can get a brief wired connection but it's no more than a few seconds before it stops. I can see a huge update waiting and I want to get the wireless adaptor working but until I get the wired connection going I'm stuck!

    TIA

    Try manually downloading the nonfree firmware package from here : http://packages.ubuntu.com/raring/al...nfree/download

    Then copy it to your Ubuntu desktop and install by simply double-clicking, or via terminal -
    Code:
    sudo dpkg -i Desktop/linux-firmware-nonfree_1.14ubuntu1_all.deb
    If we got either one working, troubleshooting the other one would become a lot easier.

    Hi, thanks for this.

    Done that and package seemed to install but still no stable wired connection?

    Just to clarify, here's the terminal printout for the installation...

    sudo dpkg -i linux-firmware-nonfree_1.14ubuntu1_all.deb
    (Reading database ... 143187 files and directories currently installed.)

    Been trying different things but still no stable wired connection.
    Does this print from Terminal throw any light on the problem?

    Don't honestly understand them :/

    Sorry I should have clarified that - it was meant to help the wifi. Is it (wireless) still not working?

    Your second post simply shows that the correct drivers are loaded. Did you try connecting to a wireless network? Does it even scan available networks yet? Try -
    Code:
    sudo iwlist scan
    If it fails to scan wireless networks, please post the output of -
    Code:
    dmesg | grep b43
    Since this card is supposed to work with the correct firmware, and the firmware should have been installed with the nonfree package, I'm focusing only on the wireless for now.

    Thanks for your help.

    I need to get the laptop working wirelessly eventually, I just thought the wired connection was essential as a first step.

    Here's the Terminal printout:

    person@person-Inspiron-1545:~$ sudo iwlist scan
    [sudo] password for person:
    wlan0 Interface doesn't support scanning : Network is down


    lo Interface doesn't support scanning.


    eth0 Interface doesn't support scanning.

    [ 33.349812] b43-phy0: The hardware RF-kill button still turns the radio physically off. Press the button to turn it on.

    I guess that stuff about the RF-kill button is a clue?

    Thanks.

    Yup, try the wireless switch or key-combination - whatever your laptop has to toggle the wifi on/off. If that doesn't seem to work, try -
    Code:
    rfkill unblock all
    Then check -
    Code:
    rfkill list
    If the wifi (apparently "phy0") still seems to be "Hard blocked", and the toggle switch doesn't work, please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

    Having pressed the button I get this:

    person@person-Inspiron-1545:~$ iwlist scan
    wlan0 No scan results


    lo Interface doesn't support scanning.


    eth0 Interface doesn't support scanning.

    It's trying to connect to the router wirelessly but not succeeding.

    I'd prefer the wireless_script's output for an "information overload".

    PS:

    Is this the wireless script output?
