This has worked for the most part. I still get a problem if the laptop enters sleep mode. When I bring it out of sleep mode there is no wifi. Also the code "frkill unblock all" (as SU) has no effect. I have to reboot the system.
Any suggestions?

Often it is the case that the wireless driver drops when the laptop goes to sleep/hibernate/cryofreeze. Let's identify your driver and write one file to see if we can reload it on wake-up. Please post:
Code: Select all
lsmod

Re: Wireless Not Enabled

Postby AlbertP on Thu Sep 29, 2011 10:38 am

chili555 & flanna:

The cause is already identified. It is the thinkpad_acpi module (thinkpad-acpi driver) which disables the wireless in rfkill.

Unfortunately we can't blacklist thinkpad_acpi, as that will also leave flanna unable to control the screen brightness and volume, use the Fn-Fx key combinations and a lot of other ACPI features. Here's some general information about thinkpad-acpi: http://lxr.linux.no/#linux+v3.0.4/Docum ... d-acpi.txt

Which is it, flanna? When you resume from suspend, is rfkill soft-blocked or is iwlagn not loaded?

After suspend:
Code: Select all
rfkill list all
lsmod | grep iwl

rfkill is hard blocked when waking up. That's the problem. The IWL driver is working OK. (EDIT: it seems like this wasn't correct)

flanna: Are you sure the wifi on/off switch/button/key can't turn your wifi back on after resume?

From the link you posted:
0x1005 0x04 FN+F5 Radio. Enables/disables
the internal Bluetooth hardware
and W-WAN card if left in control
of the firmware. Does not affect
the WLAN card.
Interesting.

flanna, please run rfkill list again, immediately after resume, before trying to turn on the wireless.

Now phy0 is hard blocked. That means, that you have to use the wifi on/off switch to get it working. If that switch doesn't turn it on, I think it's a hardware problem.
chili555 just pointed out that Wireless WAN is not related to Wireless LAN. But still there is a switch, button or key turning off the WLAN as it reports to be hard blocked.

Btw: I am using Linux Mint 11.

The wlan- Button on the side of the netbook is switched to on. In Bios the wlan is also turned to on.

I had the same problem a few years ago, there it helped to start with windows and there I could activate the wlan,
so it also runs in Linux again. This maybe help somone else.
I have no windows anymore on my netbook so this option isn't there fo me anymore.

Please uninstall the STA driver (aka wl), reboot, and install the B43 driver (apt install b43-fwcutter).

Hello, similar problem to aarroonnss, setup similar. Wireless works on windows but not on Linux mint 11.

After installing b43-fwcutter as you recommended above, network-manager applet reports firmware missing.

Is this a general problem or a recent upgrade makes it not work?

Firmware missing means usually that b43-fwcutter is not installed. If it still does not work with b43-fwcutter installed properly, please install firmware-b43-installer as well. And please use terminal so that we can see it when something goes wrong:
Code: Select all
apt install firmware-b43-installer

I think the STA driver is not properly uninstalled - it still seems to blacklist the b43 driver.

The easiest way to get rid of this is by removing the file completely:
Code: Select all
sudo rm /etc/modprobe.d/blacklist-bcm43.conf

apt install firmware-b43-installer


Hi,
here is my terminal text:

sudo apt install firmware-b43-installer
Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut
Statusinformationen werden eingelesen... Fertig
firmware-b43-installer ist schon die neueste Version.
0 aktualisiert, 0 neu installiert, 0 zu entfernen und 18 nicht aktualisiert.

seems to be allright

Edit:
Still not working.

Last week someone posted on the forum that installing firmware-b43-lpphy-installer helps to get the BCM4312 (14e4:4315) working. And mintwifi shows you're having that card.
