I just installed Ubuntu 14.04 alongside windows 8 on my Vaio laptop. Wifi is working on windows normally but it's not working on Ubuntu though I can connect to internet through ethernet.There is nothing shown in additional drivers. And iwconfig shows the following data

eth0      no wireless extensions.

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=16 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

lspci -vnn | grep Network showed:

01:00.0 Network controller [0280]: Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01)

I read somewhere that after connecting through ethernet Ubuntu automatically looks for required wireless drivers but nothing such thing has happened.

My laptop specification is at: http://www.amazon.in/Sony-Series-SVE1513ACNB-15-5-inch-Laptop/dp/B00D16KEFQ

    No help from this when I run the command lspci -nn -d 14e4: Nothing happens – Vishal Sharma Sep 26 '14 at 11:33
  • Run lspci -vnn | grep Network and post the result in question you can edit. – αғsнιη Sep 26 '14 at 11:56

  • Did you run sudo apt-get update && sudo apt-get upgrade? if you didn't that, do the commands in terminal and then type "Additional Drivers" in dash then wait for checking drivers and select wireless driver from listed driver, then click "Apply changes" to start installation. – αғsнιη Sep 26 '14 at 14:11
  • If you have an interface wlan0 then the required driver ath9k is already installed. When you click the Network Manager icon, with the ethernet detached, do you see a list of wireless networks? What happens when you click yours? – chili555 Sep 27 '14 at 01:47

Your Ethernet advice is correct, but for it to apply you also need to open your update manager and be sure to click CHECK before clicking "install updates".
