Hi, after install the b43 driver in ubuntu, my wireless card is down, here it is some important data:

sudo lspci -vvnn | grep 14e4

sudo cat /etc/network/interfaces


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo

# The primary network interface
auto eth0
iface eth0 inet dhcp


Also, in the "hardware drivers" applet, the b43 driver is up and running.

But my wireless card is not detected, wicd can't see the wireless, just the wired card, so my questions are:

1. what else should I check?
2. what steps should I use to bring up my wireless card since the b43 driver looks ok?
3. anything else?

regards

[UPDATED]
After typed: iwconfig, I found my wireless card as WLAN1, so I typed:


sudo iwconfig wlan1 up


And I've got this error:


SIOCSIFFLAGS: unknown error 132


So, I searched about it and I found this:


rfkill list


And I found that some process were blocking my card, using soft/hardware

To fix this i did:


sudo rfkill unblock all
sudo ifconfig wlan1 up


And that's it, my wifi card is up and running.


I found in wicd manager that i have to edit the info of my wireless card, previously to b43 i was using the STA driver, and my wireless card was eth2, I put that name in wicd, now I changed to wlan1 and I can see the access point.

At this point, everything is cool, i don't have any access point near at this moment but I will later, i will let you know if I have some problem later
