    Network manager / Broadcom 4306

    Please help me im a complete linux noob and have spent the last 5 days working on getting wifi to work. I know a few commands but im not entirely sure what to do. My network Manager sees my home router but when I click to connect the wifi symbol in system tray pulses repeatedly and will switch back over to ethernet symbol.

    What encryption is your WiFi pass? Are you using the desktop version or the server version with the desktop GUI installed? I'm still abit new to this too but I know some things that have helped me work with Ubuntu on other PCs/laptops

    Re: Please help network manager wont connect to wifi nothing I try works.

    Ok what I know, I am using Ubuntu 12.04lts Desktop I have a Broadcom 4306 rev.2 device, (I believe) correctly installed b43legacy firmware installer, I can see my wifi network but it just keeps acting like its going to connect then disconnects. The router is unsecured for the time being while i try to fix it connecting to begin with then move onto encrypted network.

    I have an AcerAspireOne 725 netbook with an Atheros 9485 chip and I have the same problem. I tried a WiFi dongle (Realteck chip) and it did not work either. I have searched the internet and as of yet found a solution. The WiFi will come on but it NEVER connects to my wireless router. My Laptop does fine and my wife's Kindle Fire does fine, just the netbook has the problem.

    Hi,please disconnect your wired ethernet cable
    and then try to connect to a wireless access point.
    *IF that doesnt work, then reconnect the ethernet cable.
    open a terminal ctrl/alt/t....Copy and paste the following
    one line at a time,post the results..
    Code:
    lspci -nnk | grep -iA3 net
    lsmod
    rfkill list all
    cat /etc/network/interfaces
    thanks.
