I installed Ubuntu 12.04 over a Toshiba P50-A-12z and after reformattting the disk with windows8 (I always kept windows before on a smaller partition but this time, windows8 was to bad even for me to keep so there it goes).
After doing a recommended upgrade of Ubuntu I solved some issues but I still am having problems with the wireless (I get a good wired connection though). Wireless used to work well with Windows8 before removing it from my system. I had to play with the BIOS to install Ubuntu from disk (disable the UEFI) but I doubt this should have any effect on the wireless performance. I tried many things I saw in this and other forums but nothing seems to work. I suspect the issue is on the driver that may not be available as on Intel's website say this device was released on the second half of 2013 and maybe too new for unsoported OS?. I checked on intel's webpage and even though they say the offer support for linux could not find the driver for what I think is my wireless device. Still, I hope a smart shoul from this forum could offer some help. Any help would be much appreciated. First, some useful info.
rfkill only shows bluetooth. Pressing F12 turns bluetooth on and off but no sign of wireless
rfkill list 5: hci0: Bluetooth Soft blocked: no Hard blocked: no
lshw -C network shows the device is UNCLAIMED.

lspci shows what I think is the best description of the hardware. I should have checked this info from windows8 but now is too late. Is there other way of finding out if this is the hardware or can I trust the info from lspci?

From my limited knowledge, I think the driver is alx (is it?). Below some info about it:
modinfo alx filename: /lib/modules/3.8.0-34-generic/kernel/ubuntu/alx/alx.ko version: 1.2.3 license: Dual BSD/GPL description: Qualcomm Atheros Gigabit Ethernet Driver author: Qualcomm Corporation, <firstname.lastname@example.org> srcversion: 896F432F7919E2B2C08B0B3 alias: pci:v00001969d000010A0sv*sd*bc*sc*i* alias: pci:v00001969d000010A1sv*sd*bc*sc*i* alias: pci:v00001969d00001090sv*sd*bc*sc*i* alias: pci:v00001969d00001091sv*sd*bc*sc*i* depends: mdio intree: Y vermagic: 3.8.0-34-generic SMP mod_unload modversions
Do I need to upgrade this driver or wait for a newer version?
