14e4:4315 [lenovo IdeaPad S10e] No WiFi - Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

[HugoHirsch]

With my Lenovo IdeaPad S10e, after updating to 14.10 from 14.04 the WLAN does not work anymore - the driver seems to be loaded since the hardware light flashes blue/purple, but the device is unable to connect to any WLAN. dmesg shows:

[ 1253.135805] ERROR @wl_cfg80211_get_tx_power : error (-1)

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[HugoHirsch (ubuntubugs-aiki-it)]

Thanks for pointing me to the Mainline Builds. When I tried to install
"linux-headers-3.18.0-031800rc1-generic_3.18.0-031800rc1.201410192135_i386.deb" et.al. I ran into the problem described in #1358966.

I'm not sure if the proposed patch would help to solve my problem - after further debugging it seems that the pure hardware itself seems to be recognized, but a wireless network connection cannot be established:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1358966
seems to be related to the syntax errors during kernel installation.

[penalvch (penalvch)]

HugoHirsch, if you switch to the open source b43 driver, does this provide a WORKAROUND?

Also, what was the last release that the wireless worked in?

As well, in the working release were you using the proprietary wl driver and/or the open source b43?

[HugoHirsch (ubuntubugs-aiki-it)]

I've used the wl driver with the current kernel. After installing and switching to b43 I'm able to connect, but the connection gets lost after some seconds:

[penalvch (penalvch)]

HugoHirsch, just to clarify, when you were using Trusty and it worked, which driver were you using specifically wl and/or b43?

[HugoHirsch (ubuntubugs-aiki-it)]

Christopher, wl, since I do not recall to have manually installed b43.

[penalvch (penalvch)]

HugoHirsch, the issue you are reporting is an upstream one. Could you please report this to Broadcom following https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx ?

As well, regarding b43 not working, please feel free to file a new report following the instructions in the previously mentioned article and subscribe me to it.

[HugoHirsch (ubuntubugs-aiki-it)]

Sorry for the long delay - when working on upstream kernel testing with
3.19.0-031900.201502091451 i386/32bit
to confirm bug 1422513 I realized that the internal Broadcom chip works fine after uninstalling
bcmwl-kernel-source and running with above kernel.

b43 seems to do fine in that case as lsmod indicates:
