No network connections detected! Fedora 20 pls help :(
 
I have Fedora 20 and everythin was ok when suddenly my internet got disconnected. So I tried to reconnect and nothing, and I made a mistake deleting the networks saved on the Netword Connections window. Can anyone help me? What should I do? I tried to +Add a new one and nothing, it says never used. Pls help me! Im new on Fedora.
Many thanks

Are you connecting wirelessly or through cable? (I think you want to delete the link you've written at the end of your post)

Emilie Ruvidal 12-29-2014 05:39 PM
Its wireless, wifi, how can I make it to detect them automatically again?

vincix 12-29-2014 05:50 PM
You're giving too few details, so I'm going to try to ask you step by step. Can you see any other wireless networks besides the one you're trying to connect to?

Emilie Ruvidal 12-29-2014 06:06 PM
Thanks . I wish I could add screen shot but I couldnt. No I cant see any, i deleted them to see if they show up again and when I go to "Browse network" - Windows network i get: Unable to mount location Failed to retrieve share list from server: No such file or directory

I hope you've tried simply rebooting your system, right?

Emilie Ruvidal 01-01-2015 02:16 PM
Thanks for the code. Sorry for the delay on my response but I didnt have an usb and then I got sick.
But I copy & paste the code on the terminal and this is what I got:

no wireless extensions? this means something to you?

thanks!!

If I write ifconfig I get 0 in all data, packets, bytes, etc. In enp3s0, lo and wlo1.

schneidz 01-01-2015 04:19 PM
this seems to be the problem:
Code:
wlo1 Interface doesn't support scanning : Device or resource busy
not sure what the resolution is.

schneidz 01-02-2015 10:29 AM
what does
Code:
sudo rfkill list
show ?

Emilie Ruvidal 01-04-2015 12:30 AM
command not found. I changed sudo per yum: no such command rfkill. Please use /usr/bin/yum -- help

:(

Emilie Ruvidal 01-04-2015 12:37 AM
it had happened to other people, I found this page https://bbs.archlinux.org/viewtopic.php?id=87796
but the solution provided by the person at the bottom of the page doesnt work with me, it says no such command..
do you know any similar code to this one sudo ifconfig eth1 ???

Another command similar to ifconfig would be ip:
# ip addr show dev wlan0 (or whatever the network card is)

But you're probably looking for a command similar to the one in the thread (to turn on the netw card) so it's:
# ip link set wlan0 up

Emilie Ruvidal 01-05-2015 06:18 PM
Thanks doesnt happen anything this is frustrating I Will have to restore the system again i hate this. I connected a wire directly to the modem and still no internet!!!!!i hate fedora. Thanks for ur help
