i have noticed that the iwlagn driver isnt been used by anything

all help be much appericated and will post any other commands wanted

[chili555]

Network Manager is designed to not allow a wireless connection if you have a wired connection, which you do.

https://help.ubuntu.com/community/NetworkManager

Is the wireless switch switched on?
rfkill list all

Not exactly true:

It looks busy to me!

[Hannon565]

I don't usually have wired connection avaliable just tried to it to see if works and did.
rfkill list all

I can see the wireless connection but can't connect to it with or without the wep key on it.
When connect it trys then fails. It works on every other device in the house.

Let's see if there are any interesting messages about this:
dmesg | grep -e iwlagn -e wlanThanks.

Has no one had problem like this before?

You never said what laptop you have and what wifi card you are using.
First if you are on a wire, goto system> Administration> Additional Drivers. It should do a search and find if you need a wifi driver installed. If it finds the one you need, just select it and close the dialog box. Just unplug the network cable and it should find you wireless network.
I had the same problem with my Dell Inspiron 1521, and that is all I had to do.
