Wifi - Unable to make a connection

[kdeuser]

Hello,

I have been trying for a very long time to configure wifi for Desktop multimedia pc , with no success.

My post explaining the wifi issue is posted in this link :

http://www.vdr-portal.de/board16-vid...332-avg2-wifi/

Normally, i.e. 9 times out of 10 these problems are resolved but being a German speaking forum , really need to understand what they are saying - google is not accurate enough this time.

There is something in etc/networks/interfaces script which has to be changed.

Here´s the thing, you can not or are not supposed to do this manually as the script is generated automatically.

This is my wireless card :

Ethernet controller: Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)

A post from a user here solves the issue but not for me :

http://ubuntuforums.org/showthread.php?t=2183347

Keep getting .....failed to retrieve ip no dhcp..........

Really need some help here or maybe someone knows German and can figure out what they are saying.

Thanks.

Hello Teunis,

There does not seem to be any wireless :

reel@BM2LTSR66RBin:/media/hd/home/reel$ iwconfig
tun0 no wireless extensions.

lo no wireless extensions.

eth0 no wireless extensions.

eth1 no wireless extensions.

reel@BM2LTSR66RBin:/media/hd/home/reel$

Wifi works fine because i ran a 15.04 live cd.

How do you load the wifi driver ? That's the issue.

Not a lot i can do really.

Thanks for the detailed explanation though.

You did do this:

Re: Qualcomm Atheros AR242x / AR542x Wireless not working

Thank you very much, Bryan. Saved a lot of time finding you with the same wireless card I have, with the same problem. With your info, the fix was as simple as:

1) Open a terminal
2) Type: sudo modprobe ath5k
3) Enter the admin password
4) Smile like a Cheshire cat!

Again, thanks!

If 'yes', did you then logout and reboot?

Hello Snowhog,

I am trying : sudo modprobe ath5k again.

Can not remember if i did logout and reboot.

Just ran that command again :

reel@BM2LTSR66RBin:/media/hd/home/reel$ sudo modprobe ath5k
[sudo] password for reel: 
modprobe: ERROR: could not insert 'ath5k': Invalid argument
reel@BM2LTSR66RBin:/media/hd/home/reel$

Pretty sure ´Invalid argument´ wasn´t there.

[Snowhog]

sudo modprobe -a ath5k

[kdeuser]

Hi Snowhog,

Still same ( Invalid argument ) :

reel@BM2LTSR66RBin:/media/hd/home/reel$ sudo modprobe -a ath5k
[sudo] password for reel:
modprobe: ERROR: could not insert 'ath5k': Invalid argument
reel@BM2LTSR66RBin:/media/hd/home/reel$

@vinnywright,

The command to install the wifi driver went through after an os re-install.

Logged out and rebooted , but no wifi.

sudo modprobe ath5k

Hi ,

Wifi Success !!

At last , wifi works .

The solution was simple in the end :

The following lines are placed at the end of /etc/network/interfaces :

auto wlan0
iface wlan0 inet dhcp
WPA-SSID MOVISTAR_7652
WPA-PSK 12345678

- MOVISTAR_7652 = ssid / your network name
- 12345678 = your code

Thanks for all the help.
