i also have problems but on a inspirion 1545 and my rfkill list says
user@user-Inspiron-1545:~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes

what do i do

Find out if you have dell-laptop or dell-wmi loaded:

lsmod

Whichever on it is, unload it temporarily:

sudo modprobe -rf dell-laptop <---or -wmi
sudo rfkill unblock all

Does your wireless srping to life? If so, we'll make it permanent.

hey chili555 , I would be highly obliged if you throw light on my problem which is the same as of other members here i.e., can't get my wireless to work.

I ran some commands that you listed here & they gave me the following results:

chaitanya@CHAITANYA-PC:~$ lspci -nn | grep 0280
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)
chaitanya@CHAITANYA-PC:~$ rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

This device requires firmware and there is a bit of controversy about the best way to do it. You will be our test pilot! Please get a temporary wired ethernet connection, open a terminal and do:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

Any improvement?

Yes, I do have a wired ehternet connection. I ran the commands & here's the result:

chaitanya@CHAITANYA-PC:~$ sudo apt-get install linux-firmware-nonfree

It's been more than 15 minutes & the cursor is stuck there in the WARNING line.

This is symptomatic of a failed ndiswrapper installation. Let's check a few things:

ndiswrapper -l
ls /etc/ndiswrapper
cat /etc/modprobe.d/blacklist

Thanks.

hey thanx again for your reply, sorry for taking a bit time. Here are the results:

chaitanya@CHAITANYA-PC:~$ ndiswrapper -l
chaitanya@CHAITANYA-PC:~$ ls /etc/ndiswrapper
chaitanya@CHAITANYA-PC:~$ cat /etc/modprobe.d/blacklist
blacklist bcm43xx
chaitanya@CHAITANYA-PC:~$

[chili555]

chaitanya@CHAITANYA-PC:~$ cat /etc/modprobe.d/blacklist
blacklist bcm43xx

There is no such module:

chili@Think410:~$ modinfo bcm43xx
ERROR: modinfo: could not find module bcm43xx

So you may as well remove the ineffective file:

sudo rm /etc/modprobe.d/blacklist

Now let's unload and reload the driver and see if there are any informative messages in the log:

sudo modprobe -r b43 && sudo modprobe b43
dmesg | grep b43

Either your wireless will be working or dmesg will tell us why not.

EDIT: I see you are getting excellent help from my friend Hadaka. Please continue with him.

It's stuck there.

Hadaka is your best resource.
