    Lenovo e530: 2.4Ghz not found on 13.04

    First of all, I'm a linux newb and I've installed ubuntu 13.04 in a dual boot with Windows 8 so I can learn more about linux.

    I'm using a Lenovo e530 to do the dual booting, but it's wireless didn't work initially. Today I learned about proprietary drivers and managed to get the broadcom drivers installed from the software update settings.

    My issue now is that I can only see 5GHz networks and not my 2.4GHz one. I want it to connect to 2.4GHz as that is the frequency used at my university. I've searched online to no avail. Any ideas?

    thanks,
    Sam

    Hi,

    please show the outputs of these terminal (CTRL+ALT+T) commands:
    Code:
    lspci -nnk | grep -iA2 net
    lsmod
    iwconfig
    iwlist chan
    sudo iwlist scan
    dmesg | egrep 'bcma|brcm|wl|country'
    Which country do you live? Does LAN work?

    I have work today so I will update this post later with those outputs. Thanks for replying. I am in NZ and LAN does work, it is how I got the proprietary drivers.

    Try the patched driver:
    Code:
    sudo apt-get install linux-headers-$(uname -r) linux-headers-generic dkms build-essential 
    sudo apt-get remove --purge bcmwl-kernel-source
    Check for 32 or 64bit from here "with dkms" for kernel 3.2/3.5:
