Try this: sudo rfkill unblock all and reboot. Still a bug in Ubuntu 12.04? ** Summary changed: - wifi connection via shell works, but Network-Manager stopped detecting my wifi-card recently + NetworkManager does not configure wireless interface; iwconfig and dhclient can do it -- iwl3945 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/659744 Title: NetworkManager does not configure wireless interface; iwconfig and dhclient can do it -- iwl3945 Status in “network-manager” package in Ubuntu: New Bug description: Binary package hint: network-manager My wlan-card is correct recognized. # lshw -C network *-network description: Wireless interface product: PRO/Wireless 3945ABG [Golan] Network Connection vendor: Intel Corporation physical id: 0 bus info: pci@0000:0c:00.0 logical name: wlan0 version: 02 serial: 00:1c:bf:4a:4c:8e width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwl3945 ip=134.95.92.180 latency=0 multicast=yes wireless=IEEE 802.11abg resources: irq:29 memory:f9fff000-f9ffffff and I am able to connect to the internet via # ifconfig wlan0 up # iwconfig wlan0 essid <essid> # dhclient wlan0 But in my nm-applet my wifi card is not detected, the problem occurs first in the last 2 weeks, but rebooting solved it. Today the rebooting workaround stops working. Updated all packets today, I'm still using Ubuntu 10-04.
