    Wireless connection in 12.04

    Hi,

    I can't get my wireless connection working properly. I have a Realtek RTL8111/8168B chip and when I connect to encrypted WPA network it just keeps connecting and after a while network manager asks network password again.

    What I've done so far:

    - installed wicd (no success, says bad password, though it's not)
    - installed r8168 (latest) driver from Realtek following this: http://unixblogger.wordpress.com/201...ethernet-card/

    Here's the output of sudo lshw -C network

    Code:
      *-network               
           description: Wireless interface

    I'm really in trouble, please help. Any help will be welcomed!

    Re: Wireless connection in 12.04

    r8168 is your LAN driver. Wireless is Intel, driver "iwlwifi". There is a bug with the N-mode of the driver, therefore, deactivate it via:
    Code:
    echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
    sudo modprobe -rfv iwlwifi
    sudo modprobe -v iwlwifi

    Re: Wireless connection in 12.04

    Ok, I disabled n-mode (ran all of those commands) but still no connection. Wired works ok.

    r8168 is your LAN driver.
    Thanks for clarifying, praseodym!

    Any other ideas? Thx for replying anyway

    Are you sure the password you are giving is correct??
    Can you paste the relevant logs from /var/log/syslog ?
