Public bug reported: I am using Ubuntu 11.10 and network-manager 0.9.1.90-0ubuntu5.
If I use either the network manager applet or the nmcli -p nm wifi on|off command to toggle wireless on and off, wireless networks are no longer seen even though wireless is enabled and the wireless LED is on. My Samsung N150 netbook has the rfkill.default_state=0 parameter. I do the following commands: rfkill unblock wifi nmcli -p nm wifi on nmcli -p nm wifi off nmcli -p nm wifi on At this point the wireless LED is on. If I do nmcli -p dev wifi, it shows no wireless networks. Other commands show the following: $ nmcli -p nm wifi ================ WiFi enabled ================ WIFI ---------------- enabled $ rfkill list 0: samsung-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ nmcli -p dev =========================================== Status of devices =========================================== DEVICE TYPE STATE ------------------------------------------- wlan0 802-11-wireless unavailable eth0 802-3-ethernet connected wlan0 should not be unavailable. It should be disconnected. I have to disable wireless and use the rfkill command to block/unblock wifi to get wireless working again. I suspect this issue has been fixed in network-manager 0.9.1.95 as there was a patch to nm-udev-manager.c that was committed on September 30, 2011 (core: improving handling of rfkill): http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=339229e4c698c61e20a28bfc33d8501490891427 network-manager 0.9.1.95 is not available in oneiric-proposed. Would it be possible to add the 0.9.1.95 version of the network-manager and network-manager-applet packages into oneiric-proposed?
