The wireless doesn't work on my Toshiba Satellite C55-A5281. The device originally came with Windows 8, but I removed it snd installed Ubuntu. Wireless does not work "out of the box" and there are no proprietary drivers to enable in the manager. Wired connection however does work, along with the keyboards and it's functions-brightness, sound, etc. I posted about this in the forum last-week, but no other people were able to help. http://ubuntuforums.org/showthread.php?t=2168927
Your laptop has no WiFi because it is in airplane mode, the same mode it was in when you sent it back to Toshiba. Press the Fn key and F12 simultaneously to turn Wi-Fi back on.
If this does not work check that your F12 key is working.
sudo apt-get install evtest
Run it and press the
Fn + F12 keys.
Sudo evtest then select keyboard.
evtest with the combination Fn + F8 keys (Next Track) followed by the Fn + F12 keys (Wi-Fi) followed by the the Fn + F8 keys (Next Track), followed by CTRL + C. This showed no result for the Wi-Fi key combination, but the others were as expected.
killall gnome-settings-daemon then
xev | grep keycode then press Fn + F12 to see if a keypress event is detected.
Two key press events are detected for each keystroke.
: state 0x0, key code 246 (keysym 0x1008ff95, XF86WLAN), same_screen YES,
This proves your keyboard hardware and firmware are performing correctly.
sudo rfkill event and pressing the Fn + F12 keys 4 times, gives the result
$ sudo rfkill event

This shows rfkill is intercepting the event and responding properly, but the hard stop is not responding. If you look on the Toshiba Satellite forumyou will find that this problem is pretty common, and seems to occur every time a new operating system is brought out. The response from Toshiba is always to update to the latest driver so its pretty conclusive the issue is a bug in the Intel Linux driver iwlwifi.
Next try upgrading to the latest driver using backports. Unfortunately this did not work which means the bug is not fixed yet. In fact it is bug 1538289
So you need to report the bug.
ubuntu-bug iwlwifi Follow the instructions, but instead choose 1538289 rather than opening a new bug.
Once you have done the community minded thing and reported the bug, you want your Wi-Fi back. It is reported that removing the BIOS battery, pressing the power button for 30S and the re-inserting the battery will restore the WiFi. You cannot do this as your battery is soldered in.
You could unsolder one end of the battery and hold the power switch for 30S. You should only do this if: you own the laptop, it is out of warranty, you have the tools and expertise to unsolder and solder the battery. None of these apply to you.
A rather lengthy way of switching out of airplane mode is to install Windows 7, update to the latest drivers, switch the WiFi on, remove Windows and reinstall Ubuntu. There is an easier way...
Now about that bounty
