I just installed Elementary OS to my laptop, it is an Alienware. When I was in the installation process, it asked which wifi it should connect and after confirming password it installed everything perfectly. After installation finished, I logged into the system and I only see Wired connection set by default. When I open "Network" I see Wifi is connected but "never" used. Can someone please help me?

  • Does your laptop have an Ethernet port (and if so, can you connect to the Internet via Ethernet)? I'm asking you this because when I first installed elementary OS, I couldn't connect wirelessly. WiFi icon has appeared only after I connected via Ethernet. No idea why. – a-tokarev Jul 27 at 19:46
  • @a-tokarev yes, my laptop has Ethernet port. Do i need to do anything else? Or just connect to Ethernet and that's it? – William Francis Gomes Jul 27 at 20:23
  • Open Network Settings panel and connect your laptop via Ethernet cable. After I had done exactly that, Wireless menu item has magically appeared right below the Wired menu item. So if you see Wireless menu item appear, you can switch to it and unplug Ethernet cable. – a-tokarev Jul 27 at 20:48
  • @a-tokarev, ok i tried your suggestion but i do not see any Wi-fi suggestion/option yet in my network manager. I will update my post with screenshots. :) – William Francis Gomes Jul 27 at 21:00

    Plus, as an option, after plugging in your Ethernet cable, try installing Broadcom 802.11 Linux STA wireless driver source (by executing sudo apt-get install bcmwl-kernel-source), as suggested here (elementaryos.stackexchange.com/questions/16247/…). – a-tokarev Jul 28 at 4:01

OK, so as per @a-tokarev mentioned in his last comment, by installing this bcmwl-kernel-source driver i solved the issue. So, all the people out their who is struggling with Wi-Fi connection in their Elementary OS distro you can follow either steps from below.

Solution one: Go to your AppCenter, click Installed tab and check for Drivers section. There you will find bcmwl-kernel-source driver. Click the button Free on it's right & it will install necessary drivers to activate your Wi-Fi connection.

Solution two: Go to your Terminal and copy/paste below command and press Enter

$ sudo apt-get install bcmwl-kernel-source

You have to provide your sudo password to install this. I hope this will be helpful enough.
