My laptop model is Lenovo G510 which is not able to detect wireless.
When I output of ifconfig -a
I can not see any wireless such as wlan
. My ubuntu version is 14.04
.
How can I install the driver and resolve the problem?
I have the same laptop :). If your card is a Broadcom 43412 or similar, you will need the broadcom-wl
package. To get it, use apt-get install broadcom-wl
. On reboot, wifi will start working. Otherwise, try modprobe wl
in the command line.
Hope this helps.
I've got it working with sudo apt-get install bcmwl-kernel-source*
This package can be installed even without a working internet connection, since it is present on the ubuntu install disc, under the
<mount point for the ubuntu install disc>/pool/restricted/b/bcmwl/bcmwl-kernel-source*.deb
Its prerequisites are the following (also present on the install disc):
/pool/main/d/dkms/dkms*.deb
/pool/main/f/fakeroot/libfakeroot*.deb
/pool/main/f/fakeroot/fakeroot*.deb
