View Full Version : [ubuntu] Wireless - No Icon!
June 25th, 2008, 03:40 AM
Hey, I have a problem with my Ubuntu hardy setup. Recently I managed to get the wireless network working 100%, with 4 bars and everything. I installed a bunch of updates, and everything seemed to be going fine until recently. You see, to get it working I had to right click the network icon when it booted up, and select wireless. Now though, when it boots up, the icon isn't even there! I tried going into network tools, and when I selected "unknown interface (wifi0)" it showed that it was receiving bytes and packets! This is extremely weird to me... the internet still isn't working. I am still somewhat of a noob when it comes to linux, so any help whatsoever would be wonderful. Please! :(

I have the same problem but at least I've battered it into submission a bit.
Using the examples in the HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc. posted by wieman01.
I uninstalled the network manager, edited /etc/network/interfaces, the order of things is important as the man says and the Network Manager makes a horlicks of it.
However, in spite of my efforts, only running
sudo /etc/init.d/networking force-reload actually starts the network. Thus on boot it fails to bring the interface up when networking is called. It seems to be a timeout thing because if I tail -f dmesg as I call /etc/init.d/networking I sometimes see wlan0 come available after the dhcp has given up. This does not seem to be the case when a force-reload is called.
So for now I have a script to kickstart the network.
It shouldn't be needed but...
echo "starting Wireless network"
sudo /etc/init.d/networking force-reload
My /etc/network/interfaces looks like this
iface lo inet loopback
#iface eth0 inet dhcp
iface wlan0 inet dhcp
wpa-psk a46e51e5e32d6bb6648fb9cb4a811626724774468de254421d c3578a3f
you can generate the wpa key for your site
wpa_passphrase <your essid> <your ascii key>
If anyone has any idea why networking start fails but force-reload doesn't I'd like to know.
