Hi I have been fiddlin for past day on the issues with not luck. The problem was initially I can't get wifi connection to work, ethernet is fine. I am using dhcpcd and networkmanager and the kde plasma applet. I have also used nmtui. Networkmanager picks up available connections and I have entered correct password but no good. Can't get wifi activated. Wired connection is fine. I will give you some details of both hardware and network.
This is an acer aspire 571G with a network controller a qualcomm atheros AR9462 wireless network adaptor.

I amended the above post because I thought it was a hostnaming problem but this has been rectified so I deleted a lot of stuff about that.
Re the wifi problem I tried to install the backport-patch from aur but there were errors about a config file so i gave up on that one. I read somewhere about blacklisting the acer_wmi modules maybe I will try that.
Couple things I tried
[laxle@acerlap ~]$ iw dev
phy#0
Interface wlp3s0
ifindex 3
wdev 0x1
addr 08:3e:8e:13:ac:81
type managed
[laxle@acerlap ~]$ iw wlp3s0 scan | grep SSID
command failed: Operation not permitted (-1)
[laxle@acerlap ~]$ sudo iw wlp3s0 scan | grep SSID
[sudo] password for laxle:
SSID:xxxxxxxxxxxxx
SSID: xxxxxxxxxxxxx
SSID: xxxxxxxxxx
SSID: xxxxxxxxxxx
SSID: xxxxxxxxxxxxxxx
So it seems the wifi device is working somewhat

See my other post on this thread wpa supplicant error on /dev/fd/63. I went back to basics removed all networkmanager etc and followed the wiki wireless network. Using wpa_supplicant. Wifi is now up and I am writing this from the acer wifi. So I have discovered wifi works. thats a relief. I now have to get it going on networkmanager or some automatic network manager. Now how to do this and is it going to take another few days. One thing i learnt so far is the wiki's are ok but very unclear for a newbie and one wike leads on to another.
Please be patient with newbies!

After another day of trying I think I have NetworkManager working but not sure how good, especially when I don't have a clue what I am doing I have read, re read wireless and networkmanager wikis and it was not until I looked for a step by step guide that I found this http://evilshit.wordpress.com/2012/09/1 … th-gnome3/. Although for gnome it is much the same for kde where you install kde plasma nm-applet. In this article it did specically state to remove all dhcpcd services.
In the NetworkManager wiki I did state " Note: You must ensure that no other service that wants to configure the network is running; in fact, multiple networking services will conflict. You can find a list of the currently running services with systemctl --type=service and then stop them." However it was not until I read the evilshit article that I found out dhcpcd had to be removed. For newbies wikis need to be more specific. Enspecially I think setting up ethernet and wireless connections.
