I've been looking here and elsewhere for a long time to fix my wireless issues. I upgraded to Lubuntu 14.04 and my wireless stopped working. I tried a lot of things, and then it mysteriously started working again. I later installed security upgrades and it stopped working again.
The accepted answere at this link Ask Ubuntu pointed to a script to run. The output of that script is at http://pastebin.com/B5cLYdkx.
Please help
I had the same problem. I could find a solution via google. All I did was to install the mainline-kernel. Now it is working without any problems. I downloaded the following files:
linux-headers-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb linux-headers-3.14.1-031401_3.14.1-031401.201404141220_all.deb linux-image-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb
from this site: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/
Then i used this commands:
sudo dpkg -i *.deb
After a restart i had a working wlan like in 13.10
