I have installed Ubuntu 14.04 myself. After reboot

the network (wifi) doesn't work anymore, I do not have cable, so haven't tried

ifconfig

the eth0 doesn't have inet or inet6 item

and

lspci -knn! grep Net -A2

03:00.0 Network controller (0280): Broadcom Corporation BCM43142 802.11b/g/n (14e4:4365) (rev 01)
Subsystem: Lenovo Device (17aa:0611)
Kernel driver in use: bcma-pci-bridge

quite emergency. How could I deal with it ?

Hello lad

Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. – Pilot6 Jul 08 '15 at 22:11
Do you have a wired internet access? – Pilot6 Jul 08 '15 at 22:18
@Pilot6 no, but I can download package from another computer and install I think – Hello lad Jul 08 '15 at 22:19
You need to install the driver. See the above link. – Pilot6 Jul 08 '15 at 22:20
If it does not work then post your laptop model name and output of rfkill list. On some Lenovo models it may be blocked. – Pilot6 Jul 08 '15 at 22:31
@Pilot6 it works. Thanks a lot. That saved my life – Hello lad Jul 09 '15 at 13:23
