network-manager doesn't recognize wlan0 under specific conditions
I wanted to ask this question here before posting it as a potential bug. The problem is that network manager isn't detecting my wireless card, but it can be manually started and used to connect to a wireless network. Here are the steps to reproduce the problem:
- start computer with wireless network disabled, ethernet enabled and plugged in.
- after boot and login, lock computer.
- unplug ethernet cable.
- unlock computer and try to connect to wireless network.
nm-tool gives the following data:
Type: 802.11 WiFi
Driver: iwlagn
State: unavailable
Default: no
HW Address: XX:XX:XX:XX:XX:XX
Though running the following commands allows me to successfully connect to an available wireless network:
$ ifconfig wlan0 up
$ iwconfig wlan0 essid GUESTWLAN
$ dhclient
Even after successfully connecting to a wireless network, and browsing the web (doing it now) the Network Manager still doesn't recognize the wireless has been activated. Also, strangely nothing happens if I hit the button to enable the wireless network. The following message pops up in kern.log:
- iwlagn 0000:02:00.0: RF_KILL bit toggled to enable radio.
But still nothing happens. Is there something I'm missing, or is this a bug with the Network Manager?
I've collected all the log files, and will provide them if needed. Here's my computers info:
