It's my first time installing Linux (Ubuntu) at my desktop, and it seems not to be a good start.

I have Ubuntu 16.04.3 LTS, in a Toshiba, but I'm unable to activate Wireless network, via System Settings > Network or any other way. Cable works fine!

I've tried to use rfkill unblock, different kernel, checked BIOS and still doesn't work. I believe I've tried it all, but I'm not that experienced. I hope you can help me.

  • Is there a wireless key combination or switch, sometimes called Airplane Mode, on that laptop? It appears to be set to disable wireless. – chili555 Aug 14 '17 at 18:43
  • The hardware switch Fn+F8 is on. I've tried to play with this and the rfkill output changes., but the result doesn't. :( – Reis Aug 14 '17 at 18:47
  • May we see: `lsmod | grep tosh` Also, what does the switch change in: `rfkill list all`? – chili555 Aug 14 '17 at 18:48

  • Please try: `sudo modprobe -r toshiba_acpi && sudo rfkill unblock all && rfkill list all` Is there any improvement? If so, I will propose a permanent fix. – chili555 Aug 14 '17 at 18:58
  • Thanks but no it didn't improve. I've already tried to unblock with rfkill. Nothing happens with the unblock command(i also found it strange?!?). sudo modprobe -r toshiba_acpi sudo rfkill unblock all rfkill list all 0: Toshiba Bluetooth: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 2: hci0: Bluetooth Soft blocked: no Hard blocked: no – Reis Aug 14 '17 at 19:00
  • Is there still no change in Hard blocked:yes as you press Fn+F8? – chili555 Aug 14 '17 at 19:03
  • When i press Fn+F8 the rfkill gets on, like previous post. But the System Settings->Network doesn't allow me to activate Wireless. – Reis Aug 14 '17 at 19:06
  • Correction: Now if i press Fn+F8 it doesn't change anything in rfkill output. It stays like bellow. rfkill list all 0: Toshiba Bluetooth: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 2: hci0: Bluetooth Soft blocked: no Hard blocked: no – Reis Aug 14 '17 at 19:09

    I am almost out of ideas. You might try post #19 here as crazy as it sounds: https://ubuntuforums.org/showthread.php?t=2364655&highlight=toshiba I expect part of the fix is resetting the BIOS to defaults. – chili555 Aug 14 '17 at 19:15

It worked!!! Not like suggested in the thread you mentioned but like in www.tomshardware.co.uk/forum/44040-43-wireless-function-working-toshiba-satellite

So, first disconnect your laptop from power, remove the battery, and press the power up button while holding it down for atleast 30 seconds. i know it sounds weird, but that's what i thought at first, and it worked. Ofcourse while holding down the power button, nothing will come on as there is no power source. after you're done, put the battery back on and connect the laptop to power, then switch on the laptop, your wifi should be working.

Thanks for the tip.
