[ABANDONED] Lost internet since updating

I recently ran Muon Updater (on my lappy - also running Kubuntu 14.04) and since then, I have had no internet, F12 turns wireless on/off, which I have tried - But nothing happened!

I know I will have to use a Live CD/USB but I have no idea where to start with the recovery.

Have you tried deleting your wireless profile in network manager and re-adding it ?

what’s the output from:

ifconfig

As I mentioned in my first post, I’ve created a Multi Boot USB stick. I’ve had a quick look at 16.04 and would like to have a further play around with it.

Would it make solving the problem easier if I upgraded to 16.04 instead?

What’s your opinion on 16.04, is it worth it. What’s the length of support for 14.04, am I correct in thinking it’s something like 7 - 9 years, whats the length of support for 16.04.

I just thought, how can I ‘upgrade’ without an internet connection, I can only ‘reinstall’ with my multi boot USB.
With that, I’ve just shot my own idea down, lol.

You asked, have I tried deleting the wireless profile. Sorry for forgetting to answer it earlier.

I haven’t. How do I do that?

support for both is 5 years

14.04 april 2019
16.04 april 2021

16.04 is fine unless you’re a gamer with an ATI graphics card … in which case stick with 14.04


What’s the outut from:

sudo lshw -C network

and

lspci -vnn | grep -i net

and

lsusb

and the contents of

gedit /etc/udev/rules.d/70-persistent-net.rules
sudo lshw -C network

You can modify it, as long as you keep each rule on a single

line, and change only the value of the NAME= key.

What happens if you manually load the ath9k drivers

sudo modprobe ath9k

did wireless spring to life ?

if not, what’s the output from

dmesg | grep ath

No activity with wireless…

I’ve decided to wipe 14.04 and install 16.04

Probably a good idea pooky :wink:

It would have been more complicated trying to problem solve that a clean install…
