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:

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

by **AlbertP** on Thu Sep 29, 2011 11:00 am

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?

by **chili555** on Thu Sep 29, 2011 11:04 am

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.

by **AlbertP** on Thu Sep 29, 2011 11:12 am

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.

I also reinstalled the additional drivers but it did not make any difference. Please help.

by **aarroonnss** on Sun Oct 23, 2011 4:21 am

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.

by **AlbertP** on Sun Oct 23, 2011 5:49 am

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?

by **AlbertP** on Mon Oct 24, 2011 2:58 pm

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:

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

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.
