Wireless not working on Kubuntu 14.04 Qualcomm Atheros AR9485

Question

I'm a newbie on Linux stuff and maybe the solution to my problem is obvious, but I need your help.

I decided to install Kubuntu 14.04 on my laptop (HP pavilion g6-2330sf) and the installation worked perfectly, but even if my Ethernet connection works, the wireless network refuses to be enabled.

So I spent a couple of hours trying to install drivers, NetworkManager etc... but nothing works, or should I say I can't make it work.

When typing the following command in the console $ sudo lshw -C network I get the following output:

Furthermore when using the command nmcli nm I get the following output:

I already read the following Questions:

Could someone help me activate the Wireless network?

Solution

I had a similar problem with my DELL E5420, I have fixed it by disabling the default driver. Go to system settings, Driver Manager, and unmark the marked driver. Then reboot the computer with the wireless turned on. After reboot, wait a while, then turn off wireless and turn on it again. After, try con connect to some network.

I hope this helps.

Many thanks it worked for me on Samsung Ativ i5 kubuntu-14.04 Network becomes active on resuming from sleep. Choosing the recommended graphic driver (NVIDIA) disabliing the Nouveau driver did the trick. Can this question be marked SOLVED? ddave
