My suggestion would be the Ubuntu documentation. Ubuntu has some quirky bits to it sometimes, like dns doesn't work unless you add a section to the dhcp.client file.
well,
1. First, check if you have working modem and that it is on.
2. Check to see if wifi networks are actually available.
3. If you know the dns server address, go to network connections. In wireless tab, select the
the network you want to use. click on edit.
4. go to ipv4 settings select 'automatic dhcp address only' in method menu..enter the dns server address in the dns field. for multiple address use separator ,.
5. click on save. and retry..
This thing actually works if you know dns server address.
I know my dns and able to connect successfully with automatic dhcp address only
while with automatic dhcp i am never able to access the net...
To be frank i am not a technical guy....infact i am new to linux....also i use ubuntu 11.10 and have no idea 11.04....
You should not need to read lots of documentation or research lots of web pages.
Wifi works out of the box (fresh install) automatically in Ubuntu 11.04, with a couple of exceptions:
1 - some wifi cards need additional drivers loaded before they will work
2 - if your wifi card has any kind of hardware switch - often on the side of laptops, or a special Fn-key, Ubuntu won't be able to switch it on
Case 1 should be fixed by running the System > Additional Drivers app and downloading & activating any wireless driver found.
Case 2 can be checked by running the command rfkill list all in a terminal window. If it says "hard blocked: yes" then you'll need to look for the switch.
Of course, all this assumes that you have a working wireless network in the area!
And of course that you know the encryption mode and key - you will be prompted for it.
If you still have problems we'll need to know the wifi card model.

I did the same thing setting up Linux Mint 12 (ubuntu). It did find one additional, happened to be a proprietary driver. But installing it did not help to get my wifi working.
So after a little research on what commands to use for setting up a wireless network in linux:
I used command $ lspci in terminal, wrote down my wifi card info.
Matched the wireless NIC model number to an associated driver.
Then located, downloaded, and installed the driver through synaptic package manager.
I rebooted the machine and wireless worked.
Note: lspci=list all PCI devices, ifconfig works as well.
