michi-monster,

Its mostly still there, it looks like wlp1s0 is the interface.

What does dmesg say?
Put the entire dmesg onto a pastebin site please.

michi-monster,

That all looks good. There is no sign in dmesg of the wireless ever attempting to be started.
dmesg would normally contain information about authenticating and associating. That's missing.

Lets try to start it by hand.
Code:
dhcpcd wlp1s0

Does that work?
What does it leave in dmesg - post the whole dmesg after that command please.

How do you normally control your wifi?

Lastly, if
Code:
dhcpcd wlp1s0
works and your wifi starts, you may find that you have no network connection at all because you can have packets arriving over one interface and departing over the other. If that happens, save dmesg to a file and post the file once you have rebooted.

Thank you for response.
I´v try it:
Code:
localhost ~ # dhcpcd wlpls0
sending commands to master dhcpcd process


I have added the new message from #dmesg to the end of the page http://www.edv-bildung.de/forum-please-help/

michi-monster,

gnome-shell is having problems

Code:
[ 66.438062] gnome-shell[4320]: segfault at 0 ip 00007fe7f758a569 sp 00007ffc5
14c97d0 error 4 in libupower-glib.so.3.0.1[7fe7f7579000+25000]
[ 66.829304] gnome-shell[4324]: segfault at 0 ip 00007f10c9ecd569 sp 00007ffe9
ad61b40 error 4 in libupower-glib.so.3.0.1[7f10c9ebc000+25000]


There is still nothing about wifi. Fix gnome-shell first then come back to wifi.

I gave up Gnome at grome-3.6 so start a new topic about gnome shell as I can't help with that.

michi-monster,

Start a new topic about Gnome. I can't help and others are not likely to see it in a thread about wifi.

michi-monster,

Please post all of dmesg on a pastebin site. Selected fragments are difficult to work with.

What applications do you have to control your wifi?
There are four or five ways of doing it and you can install all the options.
You must select exactly one to use.

What wifi control applications do you have installed?
Which one do you use?

What does
Code:
rfkill
say about your wifi?

michi-monster,

Your wifi setup in dwesg is
Code:
[   10.171732] rtl8192ce:_rtl92ce_read_chip_version():<0-0> Chip Version ID: B_CHIP_92C
[   10.182057] rtl8192ce: Using firmware rtlwifi/rtl8192cfw.bin

[   10.245248] rtlwifi: rtlwifi: wireless switch is on[/code/  Its all normal, as is the
[   10.972706] cfg80211: World regulatory domain updated:


It appears that the hardware is set up but the interface is never started.

I've never tried wpa_gui.
I use /etc/conf.d/net and a manually generated wpa_supplicant.conf file.

The wifi card works fine, you just keep typoing the interface name.

michi-monster - I've had a system in which the wifi card works fine but does not cooperate well with the higher levels of abstraction trying to use it to provide service. I haven't completely figured out the problem (which does not exist with ALL access points, so I suspect it is partly related to wifi signal strength; but I'm sure it's mainly an issue of misconfigured dbus, consolekit, polkit, etc), but when the rc- system, NetworkManager, and associated stuff seem to choke, I've resorted to bringing it up manually. I have a longer version with "bells and whistles" but the succinct version is something like this:
    manually edit /etc/wpa_supplicant/wpa_supplicant.conf to set up network { } stanzas for target WAPs and then reset things:
    Code:
    killall wpa_supplicant
    ifconfig wlan0 down
    sleep 1
    ifconfig wlan0 up
    sleep 1

    manually start wpa_supplicant
    Code:
    wpa_supplicant -Dnl80211 -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B

    wait -- use "wpa_cli status" to check for "wpa_state=COMPLETED"
    (my longer version does this in a while loop also providing feedback, but the basic code is like
    Code:
    while [ "${wpa_state}" != "COMPLETED" ]
    do wpa_state=$(wpa_cli status | grep -i state | cut -d'=' -f2); sleep 1; done

    Note: if the access point association process above never results in transition to a "COMPLETED" state, you have a different problem to find, and wpa_cli and your logs should be helpful, in particular
    Code:
    tail -f /var/log/wpa_supplicant.log
    has been helpful for me. Next, once the assocation is complete, manually give it dhcp support:
    Code:
    dhcpcd wlan0 -t 120

    wait -- use "wpa_cli status" to check for "ip_address" to be not blank and not "link local" (IPv4LL)
    (my longer verson does this in a while loop also providing feedback, but the basic code is like
    Code:
    while [ "${wpa_state}" == "" ] || [ "${wpa_state}" == "169.254" ]
    do wpa_state=$(wpa_cli status | grep -i ip_address | cut -d'=' -f2 | cut -d'.' -f1,2); sleep 1; done

    Note: this sometimes takes up to 30 seconds. Finally, you should be able to confirm the results:
    Code:
    ifconfig wlan0


    -- just my "grain of salt" for you


cheers

michi-monster,

dmesg:
[   10.429022] rtl8192ce 0000:01:00.0 wlp1s0: renamed from wlan0

Code:
net.wlpls0: ERROR while getting interface flags: Kein passendes Gerät gefunden


Ant P. is spot on. You are mixing up lower case letter 'l' with digit '1'. Its difficult to see.

From dmesg, your interface is called, wlp1s0.
That's wl(letter 'l')p1(digit '1')s0.

Your symlink is incorrect ... as above.

Your /etc/conf.d/net is incorrect too.
Code:
modules_wlan0="wpa_supplicant"
config_wlan0="dhcp"
You don't have an interface called wlan0. You did but udev renamed it to wlp1s0.

Well caught Ant P. - I missed that too.

Thank you-It goes ahead. :) The connections I can scan. My SSID is displayed. Unfortunately, I can not find any error with the test via wpa_config debug.
Code:

less /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
#ap_scan=0
#update_config=1

network={
        ssid="ChaosKiste"
        psk="CharlotteLink-derBetrogene"
        scan_ssid=1
        proto=RSN
        key_mgmt=WPA2-PSK
        group=CCMP TKIP
        pairwise=CCMP TKIP
        priority=5
}
wpa_supplicant_wlp1s0="rtlwifi"


Code:
less /etc/wpa_supplicant.conf.discordia
# reading passphrase from stdin
network={
        ssid="discordia"
        #psk="charlotteLink-derBetrogene"
        psk=b2924c7f1fc893c579b645d809823d79675334fb3455d9eda5107c99ad674447
}
[code]less /etc/wpa_supplicant.conf.discordia
I put the output from the scan into my homepage.

http://www.edv-bildung.de/forum-please-help/

Whats wrong now ? :cry:

michi-monster,

There are lots of SSIDs around you.
Code:
wlp1s0: BSS: Start scan result update 1
wlp1s0: BSS: Add new id 0 BSSID c8:0e:14:a3:08:45 SSID ‚ChaosKiste‘ freq 2462
wlp1s0: BSS: Add new id 1 BSSID 24:65:11:94:c9:92 SSID ‚TNGBOX1051933‘ freq 2412
wlp1s0: BSS: Add new id 2 BSSID 54:67:51:57:10:62 SSID ‚KabelBox-E52C‘ freq 2437
wlp1s0: BSS: Add new id 3 BSSID 84:94:8c:b2:0f:d8 SSID ‚HITRON-0FD0‘ freq 2462
wlp1s0: BSS: Add new id 4 BSSID ec:23:3d:d1:23:32 SSID ‚WLAN-4S56QD‘ freq 2412
wlp1s0: BSS: Add new id 5 BSSID 4a:0e:14:a3:08:45 SSID ‚Vodafone Homespot‘ freq 2462
wlp1s0: BSS: Add new id 6 BSSID 3a:0e:14:a3:08:45 SSID ‚Vodafone Hotspot‘ freq 2462
wlp1s0: BSS: Add new id 7 BSSID ec:23:3d:d1:23:33 SSID ‚Telekom_FON‘ freq 2412


It looks like you are trying to connect to
Code:
ssid="discordia"
which is not listed.
You also have
Code:
ssid="ChaosKiste"
set up, which is there.

Are you trying to connect to an Access Point that has a 'hidden' SSID?
Don't do that until you know it all works.

michi-monster,

This bit is good.
Code:
wlp1s0: State: AUTHENTICATING -> ASSOCIATING
You completed the authenticating stage, so the SSID and keys are ok.

This bit starts badly.
Code:
nl80211: Drv Event 20 (NL80211_CMD_DEL_STATION) received for wlp1s0
nl80211: Delete station c8:0e:14:a3:08:45

So after authenticating, it drops your AP so associating is bound to fail.

Then it goes on to the next AP in the list.
There may be more information in dmesg.

This sort of confusion can happen if you have more than one thing trying to manage your wifi.
The two (or more) send conflicting commands to wpa_supplicant.

michi-monster,

Don't delete anything. Its safe to have whatever you want installed as long as its not started.

The first step is to remove things from runlevels so that at boot, nothing even tries to start wifi.
Once you have achieved that, you can start wifi by hand to prove that it works.
Only after that can you set it up to start automatically.

Look at the default runlevel. Remove any/all of the following
Code:
dhcpcd
wpa_supplicant
NetworkManager
wicd
net.wlp1s0

Any of those can try to start wifi. With two or more, it isn't going to work.
Reboot.
Look in dmesg. There should be no messages about wlp1s0 being authenticated or associated.
If there is, something is still trying to start it.

Now you can try wpa_gui.

michi-monster,

That looks good. Did you grep dmesg for uthenticated and ssociated ?
Code:
dmesg | grep uthenticated
dmesg | grep ssociated
if my spelling is correct.

You can tell grep to ignore the case instead.
That is left as an exercise for the reader.
