I ran the command

sudo gedit /etc/modprobe.d/iwlwifi.conf

it gives the following output in termianal

** (gedit: 3409): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-kFLmVcCiYa: Connection refused

(gedit: 3409): IBUS-WARNING **: The owner of /home/nitesh/. Config/ibus/bus is not root!

My Wi-Fi connection appears in network manager but it does not connect to the internet. This is the output of sudo iwconfig:

wlan0     IEEE 802. 11bgn  ESSID: "RFNet"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 9C:D6:43:16:21:20

          Tx excessive retries:0  Invalid misc:1457   Missed beacon:0

lo        no wireless extensions.

eth0      no wireless extensions.

How can I restore my connection?

  • The sudo gedit just opens the file /etc/modprobe.d/iwlwifi.conf for editing, the warnings should not be relevant. Although it does look like you're logging in as root, is that so? If yes, don't. Anyway, the gedit is irrelevant, I assume you just deleted the offending line as described in your previous question right? Please say so in your question. – terdon Apr 09 '14 at 18:48
  • Never use plain sudo to run GUI applications - use gksudo, gksu or kdesudo etc. depending on the variant of Ubuntu you're running. Plain sudo does not set the appropriate environment (in particular the DISPLAY variable) for root to properly communicate with the user's desktop session bus. – steeldriver Apr 09 '14 at 19:26
  • @steeldriver yes it does. Try sudo env | grep -E 'DISPL|XAUT' and you'll see that both DISPLAY and XAUTHORITY are passed to the sudo subshell. – terdon Apr 11 '14 at 13:09
  • @terdon interesting... that appears to be true for 13.10 but not in 12.04 – steeldriver Apr 11 '14 at 13:47
  • if you want to view the content of a file use sudo cat filename. or in a gui editor use gksu gedit filename – rubo77 Apr 18 '14 at 04:22

Try watching the configuration with:

watch ifconfig

in one terminal and in another:

tail -f /var/log/syslog |grep -i Network

and observe those outputs while you try to connect to your wifi network
