My wlan device is definitely enabled.

iwconfig:

          Mode:Managed  Access Point: Not-Associated   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

I use the
Intel Corporation WiFi Link 5100

Did you check the wiki? Search for networkmanager, there is a page dedicated to it.

Re: [SOLVED] Network Manager - Device not ready

If you don't have it installed, could you install the package rfkill and post the output of "rfkill list"?

If it's software blocked enter "rfkill unblock #" where # is the number of the blocked item in the list, or "rfkill unblock name". If it reports it to be hard blocked check out the wireless switch in your laptop.

Re: [SOLVED] Network Manager - Device not ready

before:
0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

after:
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

but the device not ready error persists

Re: [SOLVED] Network Manager - Device not ready

Could you post the output of ls -l /var/run/daemons
and of
groups

ls -l /var/run/daemons:

-rw-r--r-- 1 root root 0 Apr  5 09:27 syslog-ng

groups:
lp wheel rfkill games network video audio optical storage scanner power
users networkmanager

I was originally not in the network and networkmanager group but tried adding myself in the course of reading your post, because I thought maybe that could be the reason, but it didn't change anything
I had to create the networkmanager group because it was not existent but https://wiki.archlinux.org/index.php/Groups#Groups says this group should exist.

Re: [SOLVED] Network Manager - Device not ready

Each time I start gnome, I have to start nm-applet via terminal to make it appear, but the print tells me that it was there before... Maybe that has something to do with it?

# sudo nm-applet
Password: 
** Message: applet now removed from the notification area
** Message: applet now embedded in the notification area

if I try that as root (obviously without sudo) it prints this:

GLib-GIO:ERROR:gdbusconnection.c:2270:initable_init: assertion failed: (connection->initialization_error == NULL)

Re: [SOLVED] Network Manager - Device not ready

ok, now it works partly. By applying

wpa_supplicant -Diwlwifi -iwlan0 -u

it shows me the wireless networks. But I cant connect to any of them, it doesn't react if I click on them. wpa_supplicant_gui just tells me

Could not get status from wpa_supplicant

. Any ideas?

Re: [SOLVED] Network Manager - Device not ready

Today I found out that wpa_supplicant doesn't recognize my iwlwifi driver.

drivers:
  wext = Linux wireless extensions (generic)
  nl80211 = Linux nl80211/cfg80211
  wired = Wired Ethernet driver

is all I have. Is there a way to force it to recognize my driver?

Thx for help

Re: [SOLVED] Network Manager - Device not ready

ok, solved, I tried wicd again and somewhere along the way  repaired it in my efforts to make networkmanager useable...
