Somehow, my laptop does not associate to my wireless network anymore, while it did before. Throughout the time it stopped working, I did not perform any upgrades (kernel, nor applications).
About my system:
- Laptop is a Dell Inspiron 1505
- Integrated WiFi adapter based on the Broadcom BC-4311 chipset.
- Kubuntu 12.04 with all updates in place
- Kernel is 3.2.0-34-generic
Output from lspci:
0b:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
Output from ifconfig wlan0:
wlan0 Link encap:Ethernet HWaddr 00:19:7e:06:b4:e3

There is no IP assigned, but I figure that's due to the fact that I am not connected to a wireless network.
Settings -> System Settings -> Network Settings -> Wireless Tab -> Add -> Scan does show available wireless networks. I see my network (identified by its SSID) listed, I am able to select it and add it, but I am never prompted for a password as I expected it to do.
The wired LAN connection seems to work fine.
I have disabled the splash screen so I can watch the bootup process, and there didn't seem to be anything out of the ordinary going on. Except for one thing; after logging in, KWallet did not prompt me for its password, and the laptop never connects to my wireless network.
Nothing has been changed on the router, and all of my other wireless devices continue to connect without issues.
Thank you in advance for any help you can offer. If there is any additional information you require, please don't hesitate to let me know. I am relatively new to Linux and to Linux forum etiquette, so please bear with me.
