    installing a wifi driver from usb

    Hi Guys,
    after my dell insparon mini, just wend dead slow due to being riddled with virus' i decided to install ubuntu 12.10.
    so basically i inslalled it and at the same time wiped windows.

    now the problem I have is i cant connect to the wifi, after arseing about on the net I came to a uneducated conclusion that I need a driver for the wireless thingy.

    so I followed the instructions in the help menu, and found out the make and model of my wireless thingy, its a realtek rtl8101e.
    so then on my bros desktop i downloaded the linux driver from the realtek website, on to a USB stick.

    and now i havent got a clue how to install the driver from USB stick to the netbook.

    are you sure this is the wireless card? looks more like it is the ethernet controller.
    post the output of this code

    If you open network manager, does it show a wireless adapter and say "firmware is missing"?

    +1 AFAIK the Realtek is your ethernet controller. Ubuntu ships drivers for the Broadcom 4312 standard. Go to Ubuntu Software Center and select 'Edit' from the menu and then the Option 'Software sources'. Then go to the Proprietary Drivers tab on the right. See if it lists your card.
    I'm thinking about it

    if i select network in settings, there are two options wired, or network proxy.
    wired says cable unplugged and gives a hardware address, and network proxy just has a load of unpopulated proxy boxes

    software sources has 5 tabs Ubuntu software, other software, updates, authentication and additional drivers.

    if I click on additional drivers it says No proprietary drivers are in use.

    Re: installing a wifi driver from usb

    you will need to connect with wired internet and update the package list
    Code:
    sudo apt-get update
    then in additional drivers you will find the Broadcom BCM4312 802.11b/g LP-PHY wireless driver ready for activation.

    if you don't have wired internet then try find the BCM4312 802.11b/g LP-PHY driver in .deb package format, .deb's install with a double click.

    Re: installing a wifi driver from usb

    Ok.
    I found a cable in the modem box (wifi modem, if thats what its calked feel free to correct me)
    I pluged the netbook in and through the software centre I installed additional drivers.
    Then I went to the system settings, andcin the software bit I activated it.

    I then unplugged the modem cable, and the wifi would turn on for 5 sec blasts, and deactivate again.

    So now I've reinstalled ubuntu from the pendrive, with the network cable plugged in.
    Reinstalled additional drivers.

    And gone back into software source, into additional drivers. Snd cheaked the uding broadcom box. Applied the changes.

    And whoop whoop, with the modem cable unpluged I have WIFI.

    Thank for all your help guys. I would have not beenvsble to do this without you.
