Hey everybody,
I'm completely hopeless configuring my WiFi. Recently my network-manager stopped working when trying to connect to WiFi. It must have happened after some dist-upgrade. It connects to my preconfigured home WiFi but disconnects immediatly after starting a browser. My Fn key for WiFi stopped working as well.
I therefore decided to give ceni a try and uninstalled completely the network-manager.
However I am unable to configure it properly, although I read the manual thoroughly.
I have a home WiFi and wish to connect to it automatically and when I am connected via a cable I'd like to use it in preference. Also wish the pc connects to some other wifis I know.
I tried to edit the files accordingly with no success. I only managed to turn on my eth0.
/etc/network/interfaces
Code:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-psk <Esc><Esc>]GL<Esc>]GL
wpa-ssid DigitalWorld
iface default inet dhcp
#iface home inet dhcp
The last line was a try to define a home network.
Code:
#network={
# ssid="Example WEP Network"
# key_mgmt=NONE
# wep_key0=6162636465
# wep_tx_keyidx=0
# id_str="johns_house"
#}
network={
ssid="DigitalWorld"
psk="21characterkey"
priority=15
id_str="home"
}
###############################################################################
# Default behaviour is to associate with any open access point, further
# networks can be configured with wpa_cli/wpa_gui.
#
network={
key_mgmt=NONE
}
WPA_gui doesn't work at all. Neither does the Fn key for WiFi, but WiFi seems to be activated. My Home WiFi is WPA TKIP.
What am I doing wrong please? |

Quite a lot 
Try these two files.
1. /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_roam.conf
iface default inet dhcp
iface home inet dhcp
2. /etc/wpa_supplicant/wpa_roam.conf
Code:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="DigitalWorld"
psk="21characterkey"
scan_ssid=1
auth_alg=OPEN
priority=15
id_str="home"
}
network={
key_mgmt=NONE
scan_ssid=1
priority=1
}
Now it should work (your passphrase you have to adapt to your settings of course).
scan_ssid=1 I added because you did not tell us if your ESSID is hidden or not. It does not harm.
Please refer to the manual and the WIKI for setting up WPA roaming.

Heh, I thought so 
Thank you for the prompt reply. I applied both files, but unfortunately I still does not work. 
I can't find the answer in the manual. It may be I'm too stupid for that 
When starting the system I must wait a long time because of this:
Code:
Listening on LPF/eth0/00:23:54:08:62:a3
Sending on LPF/eth0/00:23:54:08:62:a3
Sending on Socket/fallback

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 13
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 21
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
Reloading /etc/samba/smb.conf: smbd only.
Warning: mapping 'guest' to 'guest,sec=none'
mount error(101): Network is unreachable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
If there's no ethernet I would prefer the system doesn't try to connect at all, because it's useless.
As for wifi:
Code:
root@sidux-netbook:/home/petr# ifup wlan0
wpa_supplicant: wpa_action is managing ifup/ifdown state of wlan0
wpa_supplicant: execute `ifdown --force wlan0' to stop wpa_action

1. Put "auto" away in front of eth0
2. what does the root command "ifconfig" say?
3. what does the root command "iwconfig" say?
4. Is all the required firmware installed?
5. Is wpasupplicant installed?
6. Have you played around what we should know?

Thank you for your patience with me.
1. Done. Seems to have solved the problem during booting. Thank you.
2.

3.
Code:
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=11 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
4. Firmware for ralink is installed,
5. wpasupplicant as well.
6. I think I have mentioned everything. As I said. I've been using the network-manager but one day (probably after a dist-upgrade, which I am doing correctly in init 3) my connection to my home wifi stopped working - meaning that it connected succesfully and then immediatelly disconnected. Moreover, the Fn + wifi works but the led is always on (strange). |

Great! I forgot to mention you have to restart networking or simply to reboot.
Have fun!

The aptosid manual recommends ceni for network configuration.
I'd never heard of it prior to sidux/aptosid, but I've used it many times since: it's good. It is not a network manager as such (it doesn't constantly run as a process), more a configuration tool. |

Well, it only have solved the issue with ethernet delaying the booting. The wifi is still disfunctional
I wouldn't like to reinstall the whole system, however if there is a possibility to reinstall all the packages concerning networking I'm willing to do that, but apart of ceni, wpasupplicant a my wifi firmware I don't know of any |

| There is no need for reinstalling the system. If you are not sure if everything is installed you can reinstall with:
Code:
apt-get update && apt-get install --reinstall wpasupplicant wpagui
But I am a bit puzzled now why you cannot connect. I am quite sure your interfaces and wpa_roam.conf are fine now. You might check for typos.
You can also check if you as user are member of the group "netdev". You can see that in the output of
Code:
groups
A totally different option would be (as your firmware is installed) trying the WICD daemon for connecting to wireless networks. But I am not an expert with this method, but quite a few users really like that way:
Code:
apt-get install wicd

I recommend wicd to anyone who is having trouble getting ceni to satisfy their needs. I use it myself on 4 different portable boxes.
After installing wicd, you will be asked to add to add your user to the networking group for wicd. It is suggested that you do that so that you can chose different wifi networks without having to su to root and restart the wicd daemon every time.
Also, because wicd runs as a daemon you need to reboot after it is installed and you need to make sure that no other network manager is running.

Well, wicd looks very neat indeed, but I still have the same problem.
Wicd gets me connected but the connection is suddenly lost That's exactly what happened with network-manager.
Same can be confirmed with the command "wpa_cli status" which sometimes shows everything including an IP address and when executed once agait shows status: CONNECTING.
I suspect the ralink firmware :-/ There must have been a change to the package but I don't know how to confirm it. |

you wrote "gets me connected but the connection is suddenly lost" many times.
can you describe exactly how you see it connected, and how you see it suddenly disconnected?
and also, output of ifconfig when "connected" and after "disconnected"? |
