    HOWTO post a Wireless issue (ticket)

    Please take a while for the title of the thread. Do not write things like "Help wireless" and "Can't wireless". Think a little bit more, a good title can increase the chances to get help. For instance, add the Wireless brand/Ubuntu version/Machine Brand and Model.

    Please, provide details about you Wireless. The diagnoses of your problem can be easer and the solution faster.

    Here is a list of Wireless related information with their respective commands. Some commands give you a lot of output, so will be nice to include in the post only the information regarding the Wireless. You can cut it or use tools like grep, or whatever you like.

    1 ) Machine Brand and Model (PC/Laptop):
    Code:
    Get it from your product information.
    2 ) Wireless Brand, Model and Wireless Chipset:
    Code:
    $ lspci
    $ lsusb
    (hint) use grep to get only information about the Wireless
    Code:
    $ lspci -nn | grep 'Wireless Brand'
    3 ) check interface:
    Code:
    $ ifconfig
    $ iwconfig
    (hint) if the Wireless interface name is wlan0 you can also use
    Code:
    $ iwconfig wlan0
    4 ) Check for modules:
    Code:
    $ lsmod
    (hint) search for the Wireless module
    Code:
    $ lsmod | grep "wlan_module_name"
    5 ) Kernel boot messages
    Code:
    $ dmesg
    (hint) the same as in (4)

    6 ) Network configuration
    Code:
    $ sudo lshw -C network
    7 ) Scan for networks:
    Code:
    $ iwlist scan
    (hint) the same as in (3)
    Code:
    $ sudo iwlist wlan0 scan
    8 ) Ubuntu Version:
    Code:
    $ lsb_release -d
    9 ) Kernel/architecture (including 32 vs. 64 bit):
    Code:
    $ uname -mr
    10 ) Restarting the network:
    Code:
    $ sudo service networking restart
    Add this information to the post, even is the output is and error, and more if you have, and describe your issue. Please use CODE tags around the output when posting.
