Network & WiFi problem not working on lenovo G50-70

by صهيب خالد   Last Updated May 22, 2015 22:00 PM

This is my first use of Ubuntu. I installed ubuntu 14.4 but the WiFi & the Ethernet are not working. I don't understand how to activate them. What should I do?

"lspci -knn | grep Net -A2 && rfkill list "
02:00.0 network controller [0280]: Broadcom corporation BCM43142 802.11b/g/n [14e4:4356](rev 01)
          subsystem: lenovo Device [17aa:0621]
          kernel driver in use:bcma-pci-bridge

"lspci -knn | grep Eth -A2"
01:00.0 Ethernet controller[0200]:realtek semiconductor Co., ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168](Rev 10)
            subsystem: lenovo Device [17aa:380a]
            kernel driver in use:r8169

i did the steps of the link and this is the result

02:00.0 network controller [0280]: Broadcom corporation BCM43142 802.11b/g/n [14e4:4356](rev 01) subsystem: lenovo Device [17aa:0621]

You could try this it might connect to the wifi but not online, and enter this in the terminal:

    rfkill list up
    lspci wlan0
    lsmod wlan0
    nmap -v -Ir www.google.com

and then you might need to make a script and run, and type this in the script:

    #/bin/sh

            Case ! [$] in
                   /bin/sh
                   network="<the ip adr enter here>"
                   nmcli -c -d network --force-yes >>
                   resolveconf <the ip adr enter here>
            endl

and it might work fine this way.
