    Wireless connection is not established in Oracle Linux 6.4

    Me_Abhi

      Hi,

       

      I have lenovo Y500 laptop. I have installed OEL 6.4 into it. And I have a router installed in my home for personal use , where a dedicated broadband connection is attached. From windows 8 this wireless is picking up fine and I am able to do the internet. But problem is with OEL 6.4. Network connection shows a X sign over a network icon ( 2 TV sign ).

       

      I had fired below command :

      $ lscpi | grep -i wireless

      and it shows me output :

      $ 03:00.0 Network controller: Atheros Communication Inc. AR9485 Wireless Network Adapter (rev 01)

       

      And also fired command :

      $ iwconfig

      which shows me :

      $ lo  no wireless extensions.

       

      So it seems to me that , the wireless driver is not present for the adapter I have. Is my assumption correct ?

      If yes , then how to resolve that ? 

       

      Any help regarding this will be highly appreciated.

       

      Thanks in Advance,

      Me_Abhi

          Catch-22

          From what I can gather, there is no wireless support for your wifi adapter under Oracle UEK2, which is the default kernel in Oracle Linux 6.4 (OL). You might want to check the vendor support page to see if they provide any source code to compile your own driver.

           

          However, there should be support in the original RHCK kernel, which is installed too. You can change to the Red Hat Compatible kernel during boot time in the Grub boot menu, or edit /boot/grub/grub.conf for a permanent change.

          [root@vm210 ~]# modprobe -v ath9k

          FATAL: Module ath9k not found.

          I'm assuming you are not using any virtualization, because there simply wouldn't be a wifi adpater in your virtual machine.

            Hi Dude,

             

            Thanks for the above. Yes I am not using any virtualization. It works in RHCK kernel as you mentioned.
