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 : 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: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 : Broadcom corporation BCM43142 802.11b/g/n [14e4:4356](rev 01) subsystem: lenovo Device [17aa:0621] 0:ideapad_wlan: wireless LAN soft blocked: no hard Blocked: no 1: ideapad_blutooth: Bluetooth spft blocked:yes hard blocked:no
on writing "iwconfig" on the terminal
eth0 no wireless extensions
lo no wireless extensions
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.
