Try:

lspci

iwconfig

Edit: Google search gave me this: sp43742 Broadcom Wireless

Add an lsusb to that as well, as some laptops' internal wireless connects to the internal USB bus. If you are new at Ubuntu, follow the instructions below:

- open a terminal window (Applications/Accessories/Terminal)

- type:

lspci <press enter> Copy that output and paste in a reply here

lsusb <press enter> Copy that output and paste in a reply here

iwconfig <press enter> Copy that output and paste in a reply here


Also, check in System/Administration/Hardware Drivers and see if there is a driver listed there. If so, be sure it is enabled.

Since JBAlaska mentioned their search turned up some sort of Broadcom adapter, you should try the following if at all possible:

- hard-wire a connection from your laptop to your router

- open a terminal window (Applications/Accessories/Terminal)

- type:

sudo apt-get update <press enter> Wait for this to complete

- now check again in System/Administration/Hardware Drivers and see if a driver is listed there. If so, be sure it is enabled.

- disconnect the hard-wire from your laptop to the router

- right click on the Network Manager icon

- if "Enable Wireless" is not checked, be sure to check it

- wait a minute or 2

- left click on the Network Manager icon and see if wireless networks now show - if so, the driver is working

If you have any problems/questions please post back - we're here to help if we can!

One more thing I would like to ask
When I open system->administration->hardware driver, it shows two driver as follows:-
1:-broadcom b43 wireless driver
2:-broadcom sata wireless driver

but the problem is that the second one is not activated....it says while activatin it....
"sorry the installation of the driver failed
please hae a look at the log files for details /var/log/jockey.log

A couple of questions:

- is the first driver activated?

- the second driver, is it "sata" or is it "STA"?

Be sure to only activate one at a time. If one doesn't work, disable it before trying the next.

yeah the first one is activated.
So only one of those can be activated at a time?
the other one is STA (NOT SATA)...

As I understand things, yes. Also, to answer your original question about your adapter, it shows in the lspci output as:

02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)


So what you have is the Broadcom BCM4312 - a quite common adapter.

As it shows two drivers as follows:-
1:-broadcom b43 wireless driver
2:-broadcom sta wireless driver
so which of them is needed to be installed in order to access to wifi networks?

2:-broadcom sta wireless driver

Use the STA driver. Some people have trouble getting the STA driver to "Show up" or install in hardware drivers.

If this the case for you, type the following in a terminal:


sudo apt-get install bcmwl-kernel-source

Now reboot, and go to System, Administration, Hardware Drivers.

And you should be able to select the STA driver and have it activate.

Edit: you either have to have a wired connection for the above to work, or you can put the LiveCD in your drive and go to: System, Administration, Software sources and check the box below "Installable from CDROM". Then open a term and do:


sudo apt-get update

Then:


sudo apt-get install bcmwl-kernel-source

Now reboot and select the STA driver.

It would appear to my simple eyes that your wireless is working already. I have copied the output from one of your earlier posts - notice how it says "ESSID:"aircelgprs""? It would seem to me it is already connected to some wireless device that is know as "aircelgprs".
