My Ubuntu 10.0.4 LTS wireless networking cannot be enabled, on a samsung core I5 pc

can you give the make and model of the device as well as the output of:

sudo lshw -C network; rfkill list

Thanks

do you see the thick curved bars at the top of the screen? that is the wireless network manager. right click on that then select enable networking.

otherwise, do what what actionparsnip suggested.

To actionparsnip:
Here is the output:

sudo lshw -C network; rfkill list

Hi actionparsnip and other users:
actionparsnip's idea to wire up and go to Broadcom did actually work fine, though I found I actually have a Broadcom 4727 802.11n wireless adapter. I wired up with the router and executed the following steps:

1) Go to system/administration/hardware drivers and a window will pop up with all available drivers on your pc.

2) Select the Broadcom Wireless STA driver, chances are the radio button will be greyed out, left mouse click it, make it green, (ensure you are wired to the router and have a wired connection to the net) to activate the driver.

3) Ubuntu will then go to the Broadcom site in the background and download the appropriate driver, and activate it on your pc for the Ubuntu o/s. Suddenly, you will have the option to ENABLE Wireless in the network adapter setting on the toolbar, and click to enable it, and you will then be able to connect.every day.

Thanks to actionparsnip and the rest of the users for your able assistance, I learn more about Ubuntu every day from you folks.
