Intel wireless 8260 driver problems

[ojoe26]

Hello, I started using Linux a day ago, but I can't figure out how to get my wifi working. As above mentioned my system is running an Intel 8260 Chip, but it isn't working.

I already followed the instructions from this post: viewtopic.php?t=219117 .

Code: Select all

uname -a; lspci -nnk | grep -iA2 net; rfkill list all

gave me:

I am using Mint 17.3 if that helps...

Thanks in advance for your help.

That one I have fixed in a patched module

Code: Select all

wget https://www.dropbox.com/s/1bvc5vqw4429w21/iwlwifi.ko
sudo cp ./iwlwifi.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko
sudo depmod -a

Reboot and it should work

It is normal for terminal to do nothing when you are typing the password.

I don't think there ever was a file named iwlwifi-8000B. Lets try a rename of the 8000C

Code: Select all

cd /lib/firmware/
sudo cp iwlwifi-8000C-13.ucode iwlwifi-8000B-13.ucode

Reboot

[ojoe26]

Done.

Code: Select all

jules@linuxmasterrace ~ $ cd /lib/firmware/
jules@linuxmasterrace /lib/firmware $ sudo cp iwlwifi-8000C-13.ucode iwlwifi-8000B-13.ucode
[sudo] password for jules:

After rebooting still no wifi.

I don't want to patch the other module to fix, so it is time to use backports

sudo apt-get install build-essential linux-headers-generic

tar -zxvf backports-4.4.2-1.tar.gz
cd backports-4.4.2-1
make defconfig-wifi
make
sudo make install

Reboot

[ojoe26]

Wifi works now!

Thank you so much!

I notice that the wireless is hard blocked and have tried unblocking it with Fn + F5 as per user manual. I've also looked in the BIOS and it appears to be enabled. I've downloaded a driver 5300 from the Intel site and tried installing it without success.

Is there another switch on the computer to enable/disable wifi?

[Sacha]

Is there another switch on the computer to enable/disable wifi?

I've scoured the manual without success; apparently it's Fn + F5, which I presume is supposed to work with Windows, but maybe not Linux, only as I don't have duel-boot I can't verify that. Do you think this is uniquely a hardware problem? Bluetooth isn't activated either, although as I don't need it that doesn't bother me.

[JeremyB]

You could try shutting down the laptop. Remove battery and power cable, then hold the power button for 20 seconds. Reconnect battery and power cable, then reboot and see if it clears the hard block

[Sacha]

Yes I've already tried that, having researched the problem online, but I've just tried it again and it still doesn't work.

Presumably if it's hard-blocked and not soft-blocked the correct driver is installed and this is a problem with the machine?

[Sacha]

Got it !
After days of searching online and going through the manual I've just discovered a little switch on the front left which enables wifi.
Thanks for your help.

@JeremyB your posts and help were awesome! Thank you so much! With your help I was able to configure wireless networking for Oracle Linux 7 UEK4 kernel. My blogpost here:

https://sites.google.com/site/nandydand ... 0-thinkpad

summarizes getting both wireless and wired networking up on Oracle Linux 7 UEK3 and UEK4 kernels on a Lenovo ThinkPad P70 Mobile Workstation with the Intel 8260 wireless and the I219-V wired intefaces. The Oracle Linux Red Hat Compatible Kernel which comes bundled with Oracle Linux 7 works with both the 8260 and the I219-V right out-of-the box no issues perfectly.
