unable to connect to secure wifi

[roboa1983]

Hi,
I upgraded to 11.10 and initially I was unable to connect via wi-fi. I followed this link (http://www.bigfatostrich.com/2011/10/solved-ubuntu-11-10-wireless-issues/). After restarting, I can now connect to public wifi networks. However, my local wifi network is password protected (either WPA or WPA2). I have wpasupplicant installed, and I'm not sure what else I could be missing.

Here is the card I am currently using:

lspci -nvn | grep -i net
09:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express [14e4:1713] (rev 02)
0c:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02)


Thanks for the help!

Thanks for replying.
What do you mean by"

Also old hardware work better with a/b or g mode. n mode sometimes is not very stable.

Hi,
It seems my problems were solved when looking at the comments of this thread: http://ubuntuforums.org/showthread.php?t=1864163 .

I uninstalled network-manager and started using wicd. So far it has been connected and has survived a reboot.
