Announcement

are you really using 15.04? you should try 16.04 the new LTS. or 14.04 the old LTS they will both have support longer then 15.04 does since its not an LTS version.

do you see the network manager at all? it has several icons depending on its status .. disconnected it wil look like a Red monitor with a network cable on the side. connected via the wire it will look like that but with out the red coloring. this is what you want to click on to set up your wireless.

is your wifi turned on ? do you have a hardware switch or a keyboard combo to toggle the wireless card (usually fn+F2)

still can't find it? try running lshw and look in the network area for your card does it have a driver loaded for it ?

are there any properitary drivers for you in systemsetting (iirc its called driver manager) some wifi cards still need a properitary driver .

**R-Gan1410** · Oct 08, 2016, 07:59 AM

it doesn't show any option to post my my screenshot when replying.my network thing shows only wired connection and a button for airplane mode.when i try to update it shows

the required dependency 'apt(>=1.0.10.2ubuntu2)' is not installed.

.i have tried the hardware switch,it isn't is working.when i ran the lshw command under the network command the it shows driver=r8169.And finally the driver manager shows your system doesn't need any properitary drivers.please help a noob dude

**R-Gan1410** · Oct 08, 2016, 10:45 AM

Dude i upgraded to 16.04 and installed the required packages but still facing the same problem.Help me please

**R-Gan1410** · Oct 08, 2016, 11:47 AM

guys anyone help me pls. i am trying to find the solution for the past 4 hours

**GreyGeek** · Oct 08, 2016, 03:33 PM

The r8169 wifi kernel module is unsafe on a 32 bit PCI.

As a possible quick fix run the following command in a Konsole:
sudo systemctl restart networking

Or,
Copy the following script, paste it into Kate, and save it as wireless-info.sh to your home account. Mark it executable.
chmod +x wireless-info.sh
Then run it.
~./wireless-info.sh
This script will ask for your password and when it is done it will save the output as wireless-info.txt under your home account.
Upload that file, copy and paste it, into your next post.

after a 2 min google search i found this thead on ubuntu forums http://askubuntu.com/questions/45965...04-trusty-tahr
some of the suggestions there might help you.

**GreyGeek** · Oct 10, 2016, 10:35 AM

Your wifi chip is the BCM43142.

The official driver for that chip is bcmwl-kernel-source, which is in the repository.

This package contains Broadcom 802.11 Linux STA wireless driver for use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based hardware.

The BCM4312- isn't listed but support was added for it four years ago

If you have attempted to install other solutions (like the bcm43 and bmc43legacy stuff) then purge those first before installing bcmwl-kernel-source.
