Thread: wireless issue on ubuntu 11.10 alpha 2

  1. #1

    Angry wireless issue on ubuntu 11.10 alpha 2

    hi. I just installed ubuntu 11.10. everything works just fine except for my wireless card. Ubuntu automatically detected my card version and activated it for me but actually I doesn't work. I can't see wireless network list. I tried to reinstall it and I even installed ndisgtk but no success.

    my wireless card model is: Broadcom BCM4311 802.11b/g WLAN

    what should I do?

    What is the output of:

    Code:
    iwconfig
    and

    Code:
    iwlist wlan0 scanning
    "wlan0" might change from card to card so check from first output the correct interface name

    wireless drivers seems working from your output... try to connect to your router with:

    Code:
    iwconfig wlan0 key restricted wap-key mode managed essid essid-network-name
    where wap-key is router password and essid-network-name is the name of your router network.

    Re: wireless issue on ubuntu 11.10 alpha 2

    have a look at this guide to connect wifi via terminal:
    http://www.ghacks.net/2009/04/14/con...-command-line/

    anyway connecting via cli is only a workaround, if you don't see wifi handled from network indicator (panel applet) there is probably some issue in /etc/network/interfaces

    mine looks like this:
    Code:
    $ cat /etc/network/interfaces
    auto lo
    iface lo inet loopback
    if eth0/wlan0 connections are already defined in this file you won't see network lists in indicator-network.

    Have you ever tried using wicd. It is graphical program for network management. It works for both wired and wireless.
