    Cool EDIMAX EW7811un installation

    Hey guys,

    I am new to Ubuntu and not at all familiar with the terminal and the commands but my windows has started becoming slow and wanted to try this out. However, I can only connect to the internet using my EdimaX ew7811un wireless usb adapter because my laptop is that bad!

    The problem is, I cannot find the disk to install the edimax software on my ubuntu (linux) and do not have a clue where to go from here when it comes to downloading drivers or using commands etc. I'm using Ubuntu 12.10 if that helps.

    If anyone can help me, it would be soooo great!

    Cheers,
    Rhys

    Hi,

    please open a terminal with CTRL+ALT+T and show the outputs of these commands:
    Code:
    uname -r
    lsusb
    rfkill list
    iwconfig
    lsmod
    Copy the outputs to a text file and upload the content. Do you have the chance to connect via cable?

    Obviously, there is a wireless card inside? Module "b43" is for Broadcom devices. Lets check:
    Code:
    lspci -nnk | grep -iA2 net

    Unplug the stick and setup a new wireless connection after reloading the driver (or rebooting):
    Code:
    sudo modprobe -rfv b43
    sudo modprobe -v b43
    For the stick you may want to update the driver. Please show:
    Code:
    uname -r
