As you can see, you have nothing blocking your pci wireless card from working.
You should now only have to left click on the network icon and select your network.
If your network is not displayed, does it show others? If so, you will need to configure your network manually.
Let me know what is going on/what you see. Please don't leave out anything, let me know exactly what you see.

PS: You shouldn't need to run rfkill commands anymore.

EDIT: Almost forgot. Turn router off and unplug from power. Then turn computer off. Wait 5 minutes.
Power up router and let it fully reboot, then turn on computer. See if it will now show you network in the network manager.

Hi Andy

I am not sure what your line of thought is . WiFi works OK

The original problem was that the USB WiFi adapter can connect to the internet normally via the router but after a while the internet is lost but the connection to the Router is still there .

The problem does not happen with the internal WiFi connection

Re: Wifi USB Adapter stops working intermittently - AndyOpie150 - 06-21-2014

OK. I just thought you wanted the Wireless to work. The internal is fully capable of WPA2 security. Why would you want to use the USB doggle if the internal will give the same results?

Anyway. If you want to use the USB doggle then you need to kill the internal.
Type in;

Code:
rfkill block wifi0

Code:
ifdown wifi0

What's the story on the other computer? Do you still need to eventually get the wireless working on it? Unless you gave it away. Then I guess there would be no need.

Re: Wifi USB Adapter stops working intermittently - Colin23erk - 06-21-2014

Sorry

The problem happened when my Advent PC's Internal WiFi stopped connecting to my router so I used the USB WiFi adapter and although it connected successfully via the Router the Internet kept dropping out .

To see if it was a problem with the Adapter I tried it in the Samsung PC and found it was exactly the same .

At the moment the Advent is not serviceable so I have been using the Samsung to try and find a solution that will work in both PCs

Re: Wifi USB Adapter stops working intermittently - AndyOpie150 - 06-21-2014

Did it work?

Re: Wifi USB Adapter stops working intermittently - Colin23erk - 06-22-2014

Code:
colin@colin-NC110:~$ rfkill block wifi0

Bogus block argument 'wifi0'.

colin@colin-NC110:~$ ifdown wifi0

ifdown: failed to open lockfile /run/network/.ifstate.lock: Permission denied

As it failed I tried

Code:
colin@colin-NC110:~$ sudo ifdown wifi0

[sudo] password for colin: 

ifdown: interface wifi0 not configured

colin@colin-NC110:~$

The Advent gets used when my friend comes so I would like it to be able to connect to You Tube

Hello!

Am I just being ignorant, or should wifi0 be wl0 or wlan0 instead?

Re: Wifi USB Adapter stops working intermittently - AndyOpie150 - 06-22-2014

LOL. No it should be wlan0.
Thanks for catching my brain dead mistake.

Colin23erk: Replace wifi0 with wlan0 in the code. Sorry for the mistake.

EDIT: Looking at the outputs to the Advent; the code should be the same for it to. Don't know why I was thinking it was wifi0 (I help out at to many linux forum sites).

Re: Wifi USB Adapter stops working intermittently - Colin23erk - 06-22-2014

Hi This is the output

Code:
colin@colin-NC110:~$ rfkill block wlan0

Bogus block argument 'wlan0'.

colin@colin-NC110:~$ ifdown wlan0

ifdown: failed to open lockfile /run/network/.ifstate.lock: Permission denied
