Can't connect to internet with Ubuntu 11.10

For the record, when it comes to Linux, I'm retarded. I installed it a couple of weeks ago on a five year old Toshiba Equium L350 Laptop. I had been using Windows 7 but it was so riddled with viruses, malware, spyware etc I just decided to get rid of it all and install only Linux onto the laptop itself.

It's been working fine up until a couple of days ago. I gave it to my brother to use to browse online with. He'd been logging into the 'guest' account and everything was ok. However something has gone wrong and now I can no longer connect to my wireless router. It's a BT home hub, if that's of any relevance. From the drop down menu on the desktop it says 'Wired Network' and then underneath it 'disconnected'. Underneath that it says 'Wireless Networks' and below that it says 'disconnected'.

The options below that are 'Connect to Hidden Wireless Network', 'Create New Wireless Network...', 'VPN Connections', 'Enable Networking' (with a check mark next to it), 'Enable Wireless' (with a check mark next to it), 'Connection Information' (which is greyed out) and 'Edit Connections'

I've tried creating a new wireless connection, I've tried connecting to a hidden network, I've tried deleting the connection and then creating it again but none of that seems to work. It recognizes the internet connection and when I try connect to it, it takes a few minutes and the wireless bars flash and then a box appears saying 'Authentication required by wireless network', 'Passwords or encryption keys are required to access the wireless network BTHomeHub-18DA'. Underneath that is the box that says Key: and has my wireless key in it, which is correct. When I click 'Connect' the same thing happens again. And then it says 'Wireless Network Disconnected' in the top right hand corner.

I have two laptops and a desktop that connect to the internet fine, if anyone can help me it would be much appreciated. Please remember I am completely retarded when it comes to Linux and basically computers in general. Hope there are some people on here who enjoy problem solving.

I have the same problem with Ubuntu 11 on my laptop. It detects the network, type in the key, and it just pops right back up asking for the key, until eventually it just says it's disconnected. After hours of fighting with it, I just gave up. I don't like Ubuntu.

I'm sure there's a solution out there, I'm sorry I don't know what it is. Just letting you know you're not alone in this, and it doesn't have to do with being Linux-retarded. Ubuntu 10.04 worked great on the same laptop, FWIW.

Can you put a live cd in the laptop and see if the wireless works?
If it does, then it is likely a configuration issue on the laptop.
If it doesn't, then perhaps a setting was changed on your router?

If you can't get it to work with a live cd, is there any way to try using the computer with it's current configuration on a different wireless network? Perhaps at a friends home, or in a public access?

That might help you narrow down your issue.

Hope this helps.

Just had a 'hold the phone' moment.
I recall having a similar issue with my laptop and struggling with it for an hour or so before realizing that I had switched off the wireless.
I believe your laptop has a physical switch to turn wireless on and off.
If not, it should have a key combination that you can press to do the same thing.
Also, the wireless icon light should be located somewhere on your laptop.

Double check those to make sure the wireless is on.
