Toshiba Portege z835 wifi not working @ 16.04 LTS

by Fernando Ginez da Silva   Last Updated August 14, 2019 18:02 PM

I need some help to get my wifi card working. I migrated from w7 to Ubuntu 16.04 LTS and my problem started.

My wireless card is enabled into BIOS settings, and I've already pressed Fn+F8 to turn it on.

When looking too lspci -knn i've got this:

02:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak] [8086:0091] (rev 34)
Subsystem: Intel Corporation Centrino Advanced-N 6230 AGN [8086:5201]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

Checking dmesg | grep iwlwifi i've found this message:

RF_KILL bit toggled to disable radio.

I suspect that this is a indicative o the problem I'm facing.

I've already tried to do some sequences such as:

rmmod iwldvm
rmmod iwlwifi
rfkill unblock all
modprobe iwlwifi
modprobe iwldvm

My 'rfkill list all' output is:

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

And finally for reference these are my loaded modules:

This is my current kernel version:

Linux isengard 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Thanks in advance!

According to this page you can cycle through wifi and bluetooth with Fn+F8.

Can you try a solution mentioned here ?

The thing which solved my case was setting the wifi ON using hardware switch.
Try it: Boot into ubuntu in recovery mode and select enable networking
Reboot and all is done. I then had Hard blocked: no and my wifi started working
