Can't connect wirelessly, but it says I am?

[YMS_1975]

I just installed Ubuntu 12.10 on my Dell Studio 540 desktop.
When I try to connect wirelessly, the wireless connection icon (in the top right corner of the screen) says I'm connected. If I select "Connection Information" it shows that I'm connected.

But when I try to surf or update my OS, it gives me one of those failed to connect messages.

Can somebody help me???

Open a terminal window (search for "terminal" in dash).

Then in the terminal type:

sudo lshw -C network

and

iwconfig

and please produce the output here.

Actually I came across that very same post in my online search, and I already tried that.

Didn't work.
