Wi-Fi Not Working

[mandarpowale]

Hi,

I installed Ubuntu Server 14.04.2 on my office laptop's partition to dual boot with existing Windows 7(HP pavilion dv6). I setup the wi-fi connection properly during the setup

But when I first booted in to the server's command line and tried to execute 'sudo apt-get update' , it fails to download anything. How do I solve this problem? I want to install gui so practice CLI from an ebook. I want to be able to download the xwindows environment using sudo apt-get install ubuntu-desktop.

Ty in advance
Mandar

You are most likely missing the driver for your wireless card: it would help if we knew what card is installed in your machine.

in a terminal type:

lspci

Then

lsmod

also

rfkill list

post the outputs of those commands.

Ok Guys,

you need to go to the additional driver tool found by going to software center > edit> Software Sources>additional drivers

install the b43 driver from there. when it finished reboot and you should be good to go.
good luck

how do i take a screenshot, since I am running a console. I have been unable to install the desktop environment due to lack of wi-fi.

I did lspci and it yielded

08:00.0 Network controller: Qualcomm Ahteros AR9285 wireless Network adaptor (pci Express)(rev01)

lsmod yielded

cfg80211 494330 4 ath, ath9k_common, ath9k, mac80211

I could not execute rfkill list since it requires internet to install it.

Take a look at the ASK ubuntu post - last answer see if that will fix the problem.

also the following tweak may help:

echo "options ath9k nohwcrypt=1" | sudo tee  /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k
