Need help with Ubuntu 12.4 and getting my wifi to turn in my laptop :P

post #1 of 11
Thread Starter 
Hi i have a Toshiba Satellite L645D-S4106 laptop and i recently installed ubuntu 12.4 on it and i cannot get the wifi to connect for the life of me. When i tried ubuntu out before installing it, the wifi worked while windows was still installed on it. Then i installed ubuntu and now there is no wifi. I can't even flip the wifi network switch to the on position. I installed the driver from realtek for the linux driver and still nothing. Doing rfkill list all shows soft blocked: no and hard blocked: yes. Can anyone help me tongue.gif haha very frusterating. It probably is something very dumb. Thanks

Have a look at this thread:
http://ubuntuforums.org/showthread.php?t=1620697
There appears to be a solution to the same issue you are experiencing, and the user did eventually come to a solution.

Also, it appears that this uses the Realtek 8192 chipset, which from my experience, the stock kernel driver for NO DISTRIBUTION works for this chipset. For my Raspberry Pi project I used an 8192 based wifi module, which required me building the driver from source to get it working. you might be able to get it working using the PPA repository in the link above, but you may also have to compile the driver from source.

My apologies, I meant to edit my post earlier, but that PPA is hugely out of date (last update in 2011) I'll try and rummage up a better source for 8192 modules for Ubuntu, but it may take me a while.

Okay, so I found the Ubuntu bug report on Launchpad for this issue:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/902557
Basically, they know about it, and the only workaround right now is to compile and use the drivers from source.
Here is a link to the latest known working driver source tarball:
http://ubuntuone.com/2BDt3O2YqZv8QDqQWoZshQ

To build these drivers, extract the archive somewhere easy to get to and then open a terminal

Perform the following in the terminal:
Code:
cd /path/to/extracted/directory
make && sudo make install

Reboot the machine, the NetworkManager utility *should* be able to use the wireless chip, presuming it is enabled (i.e. not hard-locked)

Note, Kernel updates *may* break this driver and you *may* have to recompile/reinstall the driver until it gets fixed by the Ubuntu dev team.

Let me know if you have any compilation or installation errors, I'll try to help troubleshoot as best I can.

Also, I would recommend removing that PPA as it is out of date, and may cause issues down the road.

As dumb as it sounds if you don't have WIFI cards on when you install/run Linux sometimes it just decides they're not needed and ignores them. My netbook for example...forgot to boot with the WIFI card on before starting Linux? No wifi for me until a reboot no matter what (even with kernel modprobing). Luckily my laptop have a unique problem in which it automatically starts with wifi no matter what. biggrin.gif

Did you have it installed when you installed the distro? Might need to try installing acpi and then running it.
