I installed Fedora 23 32-bit on my DELL latitude E5500, everything went well -I guess- but my wifi is not activated and the indicator is not lit up, I checked the manual switch and it's on -so is my Bluetooth- but still no wifi

this is the output of lspci

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Read through the output of lspci for something that relates to Wireless or Network and post the line in your question - it'll give people a better chance of being able to help you. – garethTheRed Mar 8 '16 at 7:42
  • The last line of the lspci output is your Network controller, which means that it has at least been detected. What is the output of 'iwconfig' and 'ip a'? – Gasp0de Mar 8 '16 at 10:40
  • Broadcom does not redistribute the driver for this card in a way which allows us (Fedora) to legally redistribute. I don't think the situation has changed since Fedora 18, unfortunately. – mattdm Mar 8 '16 at 11:52
  • I went through the Question that mattdm linked, but still find it pretty hard to understand what OP is supposed to do. Am i getting it right that a non-free driver is needed that can not be shipped with fedora because of license issues? If so, could someone provide the OP with a link or even better with an explanation on how to install the driver? In the linked question it was only mentioned that this guy solved it by using a different kernel that included the driver. I don't use Fedora and thus can't provide an explanation on my own. – Gasp0de Mar 8 '16 at 12:03

I do not use Fedora, and thus my answer might be faulty, especially anything that is yum-related. Please correct me if this is the case. You seem to be missing a driver that (because the manufacturer of your wireless chipset does not allow that) can not be included in fedora by default. It can however be installed using yum. To do so, connect the pc to the internet using a cable, and run the following commands:

yum search kmod-wl
yum update
yum install kmod-wl

Reboot, and your wifi card should work. This is where i found the info, it is meant for Fedora 20 but probably still up-to-date. The explanation also covers how to connect to a network after getting the card to work.
