Wireless Not Enabled

[Mattia]

Hi!
I've got a problem with my wireless connection, the driver seems to be right-installed and connected, but when I try to surf the web, it just doesn't work.. I've also installed Wicd Network manager but it always give me some error, like "wrong password" (but I've tried to write it many times so I'm sure that it isn't the real problem) or "problem to find the IP".
I've used ubuntu for few months and I've installed Linux Mint 11 LXDE 32-bit two weeks ago on my netbook Acer Aspire One, so I'm not very expert as you can see..
If this can help, I wrote on the terminal "Lspci" and it gave me back "01:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
03:00.0 Ethernet controller: Atheros Communications AR8132 Fast Ethernet (rev c0)" and I've also tried "jockey-text" but it doesn't work
"Additional Drivers
Searching for available drivers..." and then nothing.. I don't know what to do!!
Thanks to everyone!

Chili555, So that you know just how useful your advice is, I have an Acer laptop (loaded with 64-bit Katya) with the same Broadcom BCM4311 wireless adapter which exhibited the same problems as the user immediately above (i.e. jogamedu).

I followed your instructions (getting almost exactly the same responses and error messages as above) which, of course, ultimately resulted in a functioning wireless network. Thank you for coming up with an elegant solution to this otherwise daunting problem!

Please let us see:

Code: Select all

dmesg | grep b43
sudo iwlist wlan0 scan

Thanks.

The 'STA' driver doesn't work correctly for this card in Mint 11. You'll need to uninstall it and use the B43 driver instead.

If you have the same card as the original poster, you should not find the module wl. If you do not have the same card, please start a new thread. Which is it?

Code: Select all

lspci -nn | grep 0280

Code: Select all

lspci -nn | grep 0280
03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1000 [8086:0083]


[AlbertP]

To everyone with a 4311 card.

Please connect to wired internet and install b43-fwcutter from Package Manager.

The posts in this thread deal with the Broadcom 4312 and 4311 cards. I suggest you start your own new thread and refer to Intel 1000 in the title. Post

Code: Select all

rfkill list all
dmesg | grep iwl

Thanks.

Amith Kumar U R:

Please make sure linux-firmware-nonfree is installed in Software Manager. You can, if needed, use a wired internet connection to install it. If it still does not work, please open a new topic.

okay.. thanks chili .. thanks Albert...

Is there any chance you'd like to make it permanent?? It looks to me like all it took was:

Code: Select all

sudo rfkill unblock all

Would you please reboot and issue that single command? If that's it, we'll tweak one file to make it persistent. If not, we'll dig deeper.

I have the same problem on my Lenovo x121e. After booting the wifi doesn't work.
When I run this code in terminal it works until it sleeps or is turned off, next wake-up or start, no wifi again:

Code: Select all

su
rfkill unblock all

This only works when logged in as su. It does not work with sudo.
I would really like to make this persistent. How can I do this?

[AlbertP]

We'll need to know what's causing your wireless to turn off every boot.

Please run this command, before running rfkill unblock all, and post the output:

Code: Select all

rfkill list

OK, here it is

Code: Select all

Can't you turn on your wireless with the on/off switch on the laptop?

[flanna]

It's already turned on. I know this because Bluetooth is available as soon as the system starts. The same switch turns on Wifi and Bluetooth.

[AlbertP]

Can you turn the switch off, and on again, to get wireless working?

[flanna]

Can you turn the switch off, and on again, to get wireless working?

Just tried that. Makes no difference.

[AlbertP]

Perhaps you can edit the file /etc/rc.local and add: rfkill unblock all (before the line that reads exit 0).

Code: Select all

gksudo gedit /etc/rc.local

Hmm... It worked.
So easy.
Thanks a lot.
