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

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:

Code:

---

sudo lshw -C network

---

and

Code:

---

iwconfig

---

and please produce the output here.

lshw -C Network :

Code:

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

Didn't work. :(

Bump!!!!

You have an ip address, so edit the connection and see that you have the type "automatic DHCP" selected, and NOT "DHCP no addresses". Of course, you router may also be unplugged from the WAN.

I checked this but still nothing. I have another laptop that connects to the wireless network just fine.

All it does is attempt to connect to the network (the wireless icon [the one with the wavy lines] moves up and down in an attempt to connect to the network) but it won't connect. Instead it says "Authentication required by wireless network" and it prompts me to enter my networks password. I KNOW that I'm entering the correct password, so that's not the problem.


Is there any other suggestions? I'M STARTING TO GET REAL DESPARATE HERE. My desktop has been down for a few days now. :(

Yes, indeed, you have an IP address. Addresses in the range of 10.42.x.x are generally used for ad-hoc, that is computer-to-computer arrangements. Is that what you intended? No?? Is that the range used by other computers on your network? I suspect they are typical home network addresses, something likke 192.168.x.x.

Please right-click the Network Manager icon and edit connections. Select Wireless and go through each tab and remove, delete, purge all extra settings except one. Be sure Mode is set to infrastructure. Please see attached. Close everything and tell us if Network Manager finds and connects to your network as expected. It may take a reboot.
