Fedora 20 no wifi networks
Hi, I did a yum update some time ago (~2months) and then lost my wifi connection. Nothing appears in the networks list. I can connect when wired. I've been searching since but haven't resolved the problem... Here are some details:

The system is up to date to date from free and non-free repos. The driver too:
yum install iwl3945-firmware.noarch
Loaded plugins: langpacks, refresh-packagekit
Package iwl3945-firmware-15.32.2.9-37.fc20.noarch already installed and latest version
Nothing to do ...
Why the
wl
driver is present ? I thought it was broadcom driver (not Intel). Also, thesudo journalctl _SYSTEMD_UNIT=NetworkManager.service > NetworkManager.txt
may give us a clue.wl
since it is an Intel Network controller (cflspci -nnk | grep -iA2 net
above). I pasted the (shortened to only today) result ofsudo journalctl
there: http://ur1.ca/hi8hy Thanks for your help.Not sure if this helps, but a live usb of Ubuntu 14.04 finds networks and manages to connect.
you can lspci for driver version if it is broadom then kmod-wl will solve the problem
