Running 3.8.0-29 Kernel On ElementaryOS Luna

After a bit of tweaking and fiddling I have managed to get the 3.8.x kernel running on the Acer Aspire V5 431. Unlike the previous time when I tried it and failed to get bcmwl-kernel-source to compile from the package manager, this time it worked with a different approach. Thanks to this post on AskUbuntu, I picked up the latest bcmwl-kernel-source ( and installed it.

The package installs without any issues and it enables WiFi for the machine. If hit the problem where the driver is shown and installed and activated, yet, you can’t seem to get the WiFi going, just make sure the other WiFi modules are blacklisted and disabled.

My blacklist looks something like this:

blacklist b44
blacklist b43legacy
blacklist b43
blacklist brcm80211
blacklist brcmsmac
blacklist ssb

You also have to make sure that the ‘b43’ is commented out in cat /etc/modules if it is present there.

I have also been able to make the Huawei EC1260 Wireless Data Modem (Tata photon+ being my provider) to work with the kernel. You will need to configure usb_modeswitch for that. After which the device will show up with the 12d1:140b profile.

The profile data looks like this:

DefaultVendor= 0x12d1

The 3.8.x kernel seems to be pretty good. The machine runs a lot cooler than what it has with the 3.2.x kernel and I am yet to run into any issues. The older kernel seemed to have the odd lock-up now and then. I have not experienced that in a day or two now. It has been a wrthwhile upgrade for me.
