I have a desktop computer which I run mostly with a wired network connection. When I start the Wicd network manager it says "No wireless networks found." Also, the command iwlist gives the same result:
# iwlist scan eth0 Interface doesn't support scanning. wlan0 No scan results lo Interface doesn't support scanning.
I have installed the driver for my network card firmware-b43-installer and I know that Wi-Fi has worked previously. My router is located nearby and several other wireless devices are connected to it. Any clues?
The output of rfkill indicates that Wi-Fi is enabled:
# rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
Here is some information about the wireless network card:
