Centos 7.3 Wifi Issue



  • While in machine which had Windows detected the Wifi Devices but in Centos no luck. Any link to install the Wifi Drivers ?


  • Service Provider

    This is where you really don't want to be using CentOS on laptops. It just isn't meant for that hardware. If you are lucky, through updates and searching on the hardware in your laptop, you might be able to get it to work. But this is probably the top reason that we avoid CentOS on end user devices, it just doesn't support the hardware.



  • Why are you so determined to make CentOS work on a laptop? If you want to study for Red Hat exam, create a VM instead. CentOS hardly support hardware the requires propriety drivers.

    Even when willing to use Fedora, I can't always make it work. My big laptop has to use Ubuntu. Nothing else can install on it, not even things based on Ubuntu like Mint!

    Not to sidetrack this but did you try setting nouveau.modeset=no on your boot options? My XPS 15 has an NVIDIA something in it and Fedora wouldn't even boot normally (couldn't even run the installer). If you add that to your boot line it just uses the Intel stuff and you can then add bumblebee or whatever the NVIDIA junk is called later.

    Learning Red hat so preferred to work on Base Machine in Centos

    May I know the location to use this ?

    But we talked about that in another thread, you'd never use CentOS or RHEL on the base machine in production, so you are doing exactly what you shouldn't be doing here - you are spending all of your time learning non-production fixes that wouldn't come up in the real world because you aren't treating CentOS like you should for learning.

    If you wanted to learn CentOS in a meaningful way, you'd run Fedora or Ubuntu or something else appropriate on the laptop, and then put CentOS in a VM, just like you'd use on the test or in production.

    Your statement should have been "Learning Red Hat so preferred to avoid putting it on the base machine."

    That question was for @scottalanmiller about his ASUS laptop.

    Oh, sorry to miss this, yes I did. It altered boot states but never made it work.

    Yes I remember already Ubuntu worked where the Fedora where the wifi didnt work.But as per your advice the Ubuntu or Fedora is good for the Base machine.I will try to install ubuntu which is stable to work with the Wifi option also ?



  • Some linux distros do NOT ship with the Firmware for the wireless devices actually installed (even if the Wifi works during the actual install process).

    I'll echo other sentiments here. If you want to learn CentOS, then do it in a VM.

    To answer the question, yes almost certainly Ubuntu will work with Wireless.

    To learn about CentOS on Ubuntu or Fedora Desktop you can install KVM and create a VM (assuming your hardware supports virtualization).

    Did you use Fedora Server rather than Fedora Workstation?

    se Fedora Server rather than Fedora Workstatio

    Fedora Workstation only



  • @Lakshmana it's possible that there just aren't drivers built into the system. You might have to install 3rd party drivers to get the wireless NIC to work.

    Why would you use an old version? This exacerbates your issues. You need to use the latest that you can get for the best driver support. Never use old products intentionally.

    Ubuntu 17.10 is most of the way through its life already, 18.04 is just three months away!
