I have been running Ubuntu 9.04 for many months without any wireless networking problems. Suddenly today, I noticed that I cannot connect to wireless networks anymore. The networks, however, do appear under the network icon with showing strong signal.

Output from lshw:
*-network
description: Wireless interface
product: BCM4328 802.11a/b/g/n
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:0c:00.0
logical name: wlan0
version: 03
serial: 00:1c:26:94:47:cb
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=wl0 driverversion=5.10.91.9 latency=0 module=wl multicast=yes wireless=IEEE 802.11abgn

Output from iwconfig:
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11 Nickname:""
Access Point: Not-Associated
Link Quality:5 Signal level:231 Noise level:168
Rx invalid nwid:0 invalid crypt:0 invalid misc:0

vboxnet0 no wireless extensions.

pan0 no wireless extensions.

Doesn't this "Access Point: Not-Associated" signal a problem?


Output from dmesg | grep -e ndis -e wlan:

[ 15.607576] udev: renamed network interface eth1 to wlan0
[ 17.068968] ndiswrapper version 1.55 loaded (smp=yes, preempt=no)
[ 17.125257] usbcore: registered new interface driver ndiswrapper
[ 36.053058] wlan0: no IPv6 routers present

Can anyone help?

Hey i had the same 'sudden-ness' too, although mine is a WPA key issue.

Possible that an network manager update has gone backwards?
