    Question Wireless-less P dv6

    Have both U10.04.2 and U10.10 installed (separate partitions) on a HP dv6.
    After initial boot in the network manager applet wireless is available and even displays two wireless routers in the neighborhood.

    After the first reboot the applet shows wireless in grey as 'Disconnected'.
    After updating through ehernet nothing changes.

    It's a Ralink RT3090 chipset.

    Extra information (gained from other installations where wireless does come up):
    Pardus 2 corporate provides the following information:
    - kernel driver rt2860
    - kernel module rt2860 sta

    Mandirva needs the rt3060 driver to be installed in order to make wireless work.

    Any help is much appreciated!

    Btw. Neither with other Ubuntu derivatives or other tuxes (Red Hat) the wireless is working.

    The module rt2860sta is built in to the current 10.10 kernel. In some cases, the device is also claimed by conflicting drivers. Let's check a few things. Please open a terminal and post:
    Code:
    lspci -nn
    lsmod | grep -e rt2 -e rt3
    Thanks.

    thanks for your very quick response.
    first have to install U10.xx again (been very busy with all kinds of distro's :/ )

    i'll get to it right away and get back to you asap with the output from the commands as you suggested (right after initial boot).

    I'm sorry for the delay but as attachment the output from the two commands (unmodified installation ubuntu 10.04.2 LTS _64 kernel 2.6.32-28-generic).

    The module rt3090sta is loaded. Did it create an interface, wlan0 perhaps?
    Code:
    iwvonfig
    sudo iwlist wlan0 scan
    Thanks.

    thanks again for your reply.
    hereby as requested the output from the two other commands (in a root terminal).

    could it perhaps be an irq problem since there are many devices loaded (bluetooth, hdmi, vga port, network, 3x usb, etc.)?
    the hp dv6 is rather bloated with hw and is used for testing newer hardware with linux (7 different tuxes installed).

    additional information:
    i did after the first test reduce some services by disabling them in 'startup applications preferences' (bluetooth manager, check for new hardware drivers, evolution alarm notifier, personal file sharing, remote desktop, ubuntu one, update notifier).
    on other computers all works well with these same settings.

    An interface, wlan0 is created. Let's do a bit more diagnostics:
    Code:
    dmesg | grep -e rt3 -e wlan
    rfkill list all
    could it perhaps be an irq problem since there are many devices loaded (bluetooth, hdmi, vga port, network, 3x usb, etc.)
    I doubt it, but you could check for errors or warnings:
    Code:
    dmesg | grep -e warn -e err

    Wink Re: Wireless-less HP dv6

    nice point of view.

    i'll switch myself off for the next 3.86 years and ponder on that a bit more.
