    Re: Belkin Surf N300 Wireless N Router F7D6301/ Ubuntu 11.04/ Lenovo Z575 - Not worki

    praseodym is right: do as he says:

    you have two drivers available;

    You will not have wireless with two drivers competing.........

    .....do as prasedym told you to do: blacklist rt2860sta as he said below

    echo "blacklist rt2860sta" | sudo tee -a /etc/modprobe.d/blacklist.conf
    sudo modprobe -rf rt2860sta rt2800pci
    sudo modprobe -v rt2800pci


    and after doing that, I think you should again tell the forum what you get with

    rfkill list all
    if all is unblocked, you should be able to configure;

    if not repeat the commands and copy and paste the results back to the forum

    Here are the results
    Code:
    echo "blacklist rt2860sta" | sudo tee -a /etc/modprobe.d/blacklist.conf
    blacklist rt2860sta
    
    sudo modprobe -rf rt2860sta rt2800pci
    network disconnected you are offline
        
     sudo modprobe -v rt2800pci

    Try

    Code:
    sudo rfkill unblock all
    If it doesnt work, unload the module

    Code:
    sudo rmmod acer_wmi

    after you have done the commands in the previous post (you may need to reboot for the last one to take effect) in case of negative results, can you post the outputs of

    Code:
    less /etc/modprobe.d/blacklist.conf | grep rt28
    more /var/log/* | grep rfkill | tail -100

    even after rebooting everything seems the same.
    Code:
     $ less /etc/modprobe.d/blacklist.conf | grep rt28
      blacklist rt2860
      blacklist rt2860sta
    
    prag@prag-Ideapad-Z575:~$ more /var/log/* | grep rfkill | tail -100

    can you run this :
    Code:
    sudo modprobe -r acer-wmi
    echo "blacklist acer-wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
    sudo rm -R /sys/devices/platform/acer-wmi/*
    sudo modprobe -r ideapad_laptop
    sudo modprobe -v ideapad_laptop
    reboot
    Code:
    sudo rfkill unblock all
    if the problem still persists post results for
    Code:
    rfkill list all
    lsmod
    less /etc/modprobe.d/blacklist.conf

    Here are the resutls.
    Code:
     sudo modprobe -r acer-wmi
      [sudo] password for prag:
      prag@prag-Ideapad-Z575:~$
      prag@prag-Ideapad-Z575:~$ echo "blacklist acer-wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
      blacklist acer-wmi
      prag@prag-Ideapad-Z575:~$
      prag@prag-Ideapad-Z575:~$ sudo rm -R /devices/platform/acer-wmi/*
      rm: cannot remove `/devices/platform/acer-wmi/*': No such file or directory
      prag@prag-Ideapad-Z575:~$
      prag@prag-Ideapad-Z575:~$ sudo modprobe -r ideapad_acpi
      FATAL: Module ideapad_acpi not found.
      prag@prag-Ideapad-Z575:~$ sudo modprobe -v ideapad_acpi
      FATAL: Module ideapad_acpi not found.
    And I am unable to find devices folder. Should I try some different commands as ideapad_acpi is not found. Would you like to see results of any other commands.?

    I did a kernel upgrade by following the link, http://marcin.juszkiewicz.com.pl/201...u-natty-11-04/

    The kernel upgrade ended up with Black screen. I installed Linux 3.0 kernel image, module init tools and procps. Then did a reboot and chose ubuntu in bootloader. After that am stuck with black screen.

    So I logged into the earlier kernel version of ubuntu to recover from the blackscreen and found that Wireless network works.

    Now shall I proceed with removing the older kernel (as internet is working here).? Will the wireless connection work in the upgraded kernel too.?

    make sure you install backposrts package first this should prevent the kernel upgrade from editing your wireless modules
    Code:
    sudo apt-get install --reinstall linux-backports-modules-wireless-generic
    i am a little bit confused how did you exactly managed to fix the problem? what did you do?
