Hello,
I have recently installed , Fedora 20 Os in my PC but the Wireless don’t work .
Can anyone help me to fix this ?
Thank you.
Open a terminal and post the output from running these commands:
lshw -C network
and
lspci -vnn | grep net
and
lsusb
[root@localhost chrifmarwen]# lshw -C network
bash: lshw: unknown comand…
[root@localhost chrifmarwen]# lspci -vnn | grep net

[root@localhost chrifmarwen]# lsub

Is this a USB wireless adapter ?
Try
lsusb
again, as you made a typo in your last attempt 
No it’s not usd wireless, it’s embeded.
Wired connection work fine .

Subject: No Wireless connection Fedora 20 (SOLVED)

Hello,
I’ve another problem after updating feedora 20, but now the wireless led is on but no internet connection.

You might need to install it:
su

yum install rfkill

Soft blocked: no
Hard blocked: no
1: acer-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
5: hci0: Bluetooth

Hard blocked: no
Let’s try uninstalling/reinstalling the driver again … make sure you’re connected to your router with an ethernet cable, then run:
su

yum remove akmod-wl
then
yum install akmod-wl
I make this done but no result : the led is off now , i tried fn + f3 to activate it but it dosn’t.
