[ABANDONED] No Wireless On Fresh Install Of Kubuntu 14.04

Linux Support
1

well, the subject header basically explains my problem.
I did a little searching and found something but it was related to a DELL, which I’m using an HP Pavilion and didnt want to type anything which might corrupt my install as I’m guessing it might be slightly different. I did gind a command which might help diagnose…

You may have reached a bit of an impasse here … the Intel Dual-Band Wireless-AC 3168 requires the 4.8 kernel to work.

And I don’t know if the 4.8 kernel will work well with 14.04 … it’s an easy install (and supported) in 16.04, but i have no idea what it’ll be like in 14.04

You can give it a shot if you like, but don’t blame me if it breaks things…

To install the 4.8.17 kernel (in 64bit 14.04), connect to your router with an ethernet cable, then open a terminal and run thee commands in sequence:

mkdir ~/Desktop/4.8-kernel

then

cd ~/Desktop/4.8-kernel

then

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.17/linux-headers-4.8.17-040817-generic_4.8.17-040817.201701090438_amd64.deb

then

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.17/linux-headers-4.8.17-040817_4.8.17-040817.201701090438_all.deb

then

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.17/linux-image-4.8.17-040817-generic_4.8.17-040817.201701090438_amd64.deb

then

sudo dpkg -i *.deb

then REBOOT.

Once rebooted, check you’re booted to the 4.8 kernel with:

uname -a

if you are … check if wireless works.

3

I’ll give it a shot, it does break the system, I can always use the boot repair disc or boot using an install disc and try and repair it from there. Or if unrecoverable, just bite the bullet and install 16.04…

4

Just thought I’d copy this before I rebooted

sudo dpkg -i *.deb

Problem is, now how do I get my laptop to connect to wireless when there’s no option to connect to wireless, only hardwired.

7

What’s the output from:

sudo lshw -C network

and

rfkill list

and

sudo iwlist scan

[EDIT]

and post the output from

inxi -Fz

and we’ll see if we can rectify those missing firmware messages.

for my reference:

Here’s all the info you requested…

Connect to your router with an ethernet cable and run these commands in sequence:

sudo apt-get update

then

sudo apt-get install git

then

mkdir ~/linux-firmware

then

cd ~/linux-firmware

then

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

then

cp -v ~/linux-firmware/linux-firmware/iwlwifi-3168-21.ucode /lib/firmware/

then

cp -v ~/linux-firmware/linux-firmware/iwlwifi-3168-22.ucode /lib/firmware/

then

sudo update-initramfs -u -k all

Once that’s finished … REBOOT

Test wireless ?

I’ve done all you say, on the last one I got this…

Just going to reboot in a sec…

13

The wireless connection is there but I don’t know how to enable/set it up!

14

Something happened and I ‘lost’ the 2 printers I had installed and decided I would ‘bite-the-bullet’ and install 16.04
