Ubuntu: Wireless not working.Toshiba P50-A-12z-. Artheoos. Ubuntu 12.04 (LTS) [duplicate]


This question already has an answer here:

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?

lspci  03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)  04:00.0 Ethernet controller: Qualcomm Atheros QCA8171 Gigabit Ethernet (rev 10)  

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, <nic-devel@qualcomm.com>  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?




Thanks a lot! I followed the solution posted by chili555 in the following link


And now my wireless works great. Again, thanks a lot. You guys rock!

PS. Don't get frustrated with people that don't find answers already posted in the forum. I spent hours browsing different solutions but could not find the right one until I was directed to it.

Just in case it helps to other non-expert people (like me) reading this post. My system (12.04) showed only up to /lib/firmware/iwlwifi-6050-5.ucode and no signs of the required 7260 that was needed for my intel device (see above). Now the 7260 ucode file is there. One obvious thing I tried a couple days ago was ubuntu 13 but could not even see the live CD (computer just stopped working in the middle of reading the DVD and I tried this multiple times with identical results).

I might ask your help again with my screen in the future (I think it has some compatibilty issues but works well for most prurposes so no urgency here) if I don't find a solution in the older posts.
