wireless card not detecting wireless internet

karantani · 2012-06-10 20:17:15

wicd stopped detecting my wireless internet,i dont really know when this happened because i came back from a three week vacation and i just found that out and it also my bluetooth adapter is not decected either,i think it has something to do with my upgrade to gnome 3.4

ratcheer · 2012-06-10 20:19:57

I think Gnome will probably be using Network Manager, instead. I have read articles in the past about having to remove Network Manager in order to use wicd. I am not sure, because I use Network Manager, myself.

1. Have you tried to scan for your wifi using another device? - For instance smartphone or another computer?

2. Like Ratcheer mentioned, you're most likely going to have to remove network manager in order to use wicd without problems.

Try to do this (In a terminal)

ifconfig wlan0 down
ifconfig wlan0 up
iwlist wlan0 scan

#(The previous thing should give you information about all the networks it can find, if it doesn't find anything try:
killall wicd
killall networkmanager
killall network-manager-gnome

And then try iwlist wlan0 scan again

If you get results using that, try to connect to it

Assuming you're not using any protection on your wifi, type this:

iwconfig essid NAMEOFYOURWIFI

Then run iwconfig again, to see if it has gotten in touch with your router.

Then finally, run dhclient wlan0 #To get an ip adress

If this works, then at least your internet, and computer is fine!

Assuming this works, try to use networkmanager to connect to the wifi, or re-install wicd, and rebooting(rebooting might just be crazy enough to work!)

If you would, can you post the output of ip addr ??

karantani · 2012-06-11 00:19:25

i did what zaek siad and i got this and i also removed wicd and wicd-gtk

[milio@arch-m ~]$ sudo ifconfig wlan0 down
Password:
wlan0: ERROR while getting interface flags: No such device
[milio@arch-m ~]$ sudo ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device
[milio@arch-m ~]$ sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning.

[milio@arch-m ~]$ sudo killall wicd
wicd: no process found
[milio@arch-m ~]$ sudo killall networkmanager
networkmanager: no process found
[milio@arch-m ~]$ sudo killall network-manager-gnome
network-manager-gnome: no process found
[milio@arch-m ~]$ sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning.

do you guys think it has something to do with this

Very well. I did not get my output though

It would appear your interfaces are MIA. That is what I was looking for anyway. Can you post the output of
lspci -nn
and of
lsmod
??

Edit: Are you using initscripts or systemd ?

First, Jason is correct. Please use BBCode code tags (There are always hints in the link under post text boxes)
Second, I do not see the ath5k kernel module. What happens if you
modprobe ath5k

Well.
I see both your wired interfaces are there. Your Atheros is indeed not loading.

The fun part: I don't have an Atheros card, but I was able to sudo modprobe ath5k just now without any problems ... except of course, no device appears

Which kernel are you running (what is the output of uname -a )??

karantani · 2012-06-12 02:26:41

[milio@arch-m ~]$ uname -a
Linux arch-m 3.3.8-1-ARCH #1 SMP PREEMPT Tue Jun 5 15:20:32 CEST 2012 x86_64 GNU/Linux

months ago i installed aircrack-ng along with compat-wireless-patched from the AUR and i still have them installed,do you think it has something to do with it?

Maybe. You might try removing them.

I note that I am running Kernel 3.4.1-1 from testing.

I do not recommend this, but... Read the bit about testing in this article
If you are comfortable with the idea, you might turn on the testing and community-testing (both are required), do a pacman -Syu, and reboot.

See if the up and coming kernel helps.

karantani · 2012-06-12 03:43:26

ok,im gonna remove the from my system and reboot and try to see what happens and let you know .
how stable or secure is enabling testing and community -testing on my system?,because i've always wondered about that if you run into problems a little too often,or i can just enable it and after a couple of weeks desable it and see what happens

karantani · 2012-06-12 04:25:41

ok let me tell you what happened,i removed aircrack-ng and compat-wireless-patched with yaourt -Rs and then rebooted and after that everything was back to normal and my bluetooth adapter is working fine again:), i didn't need to enable testing,probably i'll enable it in the future just to test it,i disabled (!) networkmanager again and reinstalled wicd.
thanks a lot guys

I have never considered the question as to whether it is secure. It is fairly stable; to the point where I have never had to create any meaningful bug reports (The purpose of testing in the first place). Yes you can turn it on, use it, turn it off and downgrade -- most of the time. Every now and again, something happens that requires a chroot to straighten out. I came from Gentoo and have built a LFS, so chroot comes naturally

Anyway, glad your system is back up without having to take extraordinary measures.
