Trouble Connecting and/or Using
Okay, I'm fairly new to this stuff, but my wife has a Compaq Mini that uses the Ubuntu 10.04 LTS operating system. It is connect via wifi to a Linksys E900 router. It says it is connected, but Firefox 15.0.1 (Mozilla Firefox for ubuntu canonical - 1.0) can't access the net, saying server not found. I have it set to "Auto-detect proxy settings for this network", though I've tried the no proxy setting as well. The network proxy preferences are set to direct internet connection (under system > preferences > network proxy) and the network setting for the connection as in Ad-hoc mode, using a WEP 128-bit passphrase for security. I thought I made a stupid mistake in the above settings (and still might have), but I have another wrinkle. I've tried using Update Manager, and tell it to check for updates manually. This never caused a problem before, but it "could not download all repository indexes". It says there are network problems (though it says the network connection is active 100%). It has many listed mistakes that use this format (the first of the errors):
Failed to fetch http://us.archive.ubuntu.com/ubuntu/...id/Release.gpg Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
Can someone tell me what the heck I'm doing (wrong)? I'm staying on this page, updating often, just so I can get this taken care of and get my wife off my back :) Thank you for your time...
Re: Trouble Connecting and/or Using
1. Has your Compaq connected OK in the past?
2. Have you tried rebooting the router?
Re: Trouble Connecting and/or Using
1. While there have been occasional problems in the past, generally it has worked fine. However, this is a new router. The router is working for all other computers in the house.
2. Rebooting the router and everything else individually was one of the first things I did and didn't help.

Bump?
If it matters, it was connecting to the previous linksys wifi router with no issues, so I'm really thinking it isn't the router...
Re: Trouble Connecting and/or Using
Is there any more info I can provide that might help aim me towards a solution?
Re: Trouble Connecting and/or Using
There are a few possibilities
1. The DNS server isn't working correctly
To test this in your web browser try this as an address
212.58.241.131
This should take you to the bbc home page. If it does then you can use the DNS server at 8.8.8.8. I can give you the command to do this
2. You are not connected to the network you think you are to test
Code:
ifconfig; route -n; ping 8.8.8.8
Post results back here and we can advise further

Wifi always brings its own "can of worms" into the equation so, as a temporary measure, I would exclude this. Just link the computer to the router with an ethernet cable and see if you can then browse the web.
If this does work then it means that the router internet connection is configured correctly and that the problem is with either the router or the computer wifi configuration.

Warren: To 1 above, I still had no connection through Firefox or special result with the ip addy you gave. Then I put the code you provided on the Terminal and got the following:

Connect: Network is unreachable
[Note: This is while the wifi connection thing says the wireless network connection is active 100%]
Zill: Oddly enough, when I tried a corded connection, my connection icon menu wouldn't acknowledge it and I still got no connection for firefox or update manager. Now I'm really confused. HELP!?!
Re: Trouble Connecting and/or Using
What's the output of
Code:
cat /etc/network/interfaces

What is the (local) IP address of your router?
