I have just installed Ubuntu 12.10 in my laptop. I am not able to connect to my D-Link N150 Wireless Router which i was able to do when I had Windows XP.
The Problem
Everytime I log on to my Ubuntu, a window would pop up now and then saying:
"Authentication required by wireless network".
When I type in the password, the wireless icon would blink for a second and again the window pops up. I googled on this and followed all the steps to find out what is going wrong from my OS. I couldn't figure out anything.
Please help me to fix this issue.
What I Did
Whether my wireless adapter is recognized?
Yes it is. The below logs say that.
sudo lshw -c network *-network description: Wireless interface product: PRO/Wireless 3945ABG [Golan] Network Connection vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 02 serial: 00:1b:77:8e:46:61 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwl3945 driver version=3.5.0-17-generic firmware=15.32.2.9 latency=0 link=no multicast=yes wireless=IEEE 802.11abg resources: irq:44 memory:edf00000-edf00fff
Whether my wireless device drivers are installed?
I guess drivers for PRO/Wireless 3945ABG [Golan] by Intel are preinstalled in this Ubuntu version.The above logs
driver=iwl3945 driver version=3.5.0-17-generic firmware=15.32.2.9
says that drivers are there. But i am not sure whether the version3.5.0-17 is supported by my wireless adapter 3945ABG.I tried this command
rfkill list
to see if the wireless is blocked?Soft blocked :no hard blocked :no
In my Network connection manager I have the following settings:
- SSID:
********
- Mode: Infrastructure
- IPv4 settings - Method: Automatic (DHCP) addresses only
- IPv6 settings - I have made it ignore
- Wireless security : WPA & WPA2 Personal.
- SSID:
More Info
- I have installed Ubuntu 12.10 from a USB stick where i was able to connect to my wireless network during installation.
- The Additional drivers tab in the Software Sources center is empty. I have no idea why it is empty (if in case I need to install any extra drivers to fix this wireless problem of mine).
- I have spent three days googling to fix this issue. I am still hopeful I would be able to fix this with yours help.

appearing from the time you attempt the connection to the moment the error message appears? That will probably give more information on what exactly happens.NetworkManager[721]: get_secret_flags: assertion
seems to indicate this is a bug. Assertions are severe errors. Have you tried updating all packages and reboot? (using wired network)
