Hey Folks,

I just turned my Windows 7 Dell Inspiron 1720 into a Fedora 23. The laptop had wireless connectivity as a Windows 7 laptop, but after I installed Fedora 23, there is no sign of wireless connection. When I go to the top-right down arrow icon, I don't even see an option for wireless networks. All I see is that my battery report and the name of one user whom I created during the installation.

Below please find the output of lspci command:

lspci -nn | grep -i net

03:00.0 Ethernet controller [0200] : Broadcom Corporation BCM4401 -B0 100Base - TX [14e4:170c] (rev 02) oc:00.0 Network controller [0280] : Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

Please assist. Many thanks in advance.

If you click on the network icon, do you see any wireless networks? if you open the terminal and type ifconfig can you see a network device that looks like wlp2s0? another command from the terminal would be iw dev which will tell you all the details of the wifi adapters on your laptop

Do you have linux-firmware package installed?

dnf install linux-firmware

ifconfig's output has 3 entries. ethh0, lo, & virbr0.

dnf innstall linux-firmware command failed, as the machine cannot access s/w repos outside (no wireless)

iw dev command produced nothing at all.

Is the wireless switch on? The wireless switch is on the left hand side of the laptop...

Yes, the wireless switch is on. BTW, I'm currently connected through wired connection. I went ahead and installed linux-firmware by "dnf install linux-firmware" command and still nothing.

  • Move the computer to within 3-9 feet (1-3 meters) of the wireless router.
  • Make sure the wireless switch is on. It will be either a sliding switch on the left or right side edge of the computer, a key combination or single key. Toggling this switch will turn all the wireless connections (Wi-Fi, Bluetooth and Mobile Broadband) on and off, at the same time. Look for a wireless icon
  • From the Start page, click Desktop.
  • Right-click the network icon the notification area of your taskbar, and then click Troubleshoot problems and follow the instructions.
  • Turn off and then turn on all the devices on the network to synchronize them
  • Make sure the latest driver is installed
  • Make sure the correct network name (SSID) and passphrase or network key (if any) were used to create a profile.
  • Configure the wireless adapter settings for optimal performance
  • Update the computer to the most current BIOS
  • Run the Network Adapter Diagnostics with help of Dell Inspiron 1720 Manual.
