To install the restricted drivers (broadcom wireless drivers) in the ubuntu 11.04 Natty Narwhal without a wired Internet connection.

Insert the Ubuntu 11.04 (Desktop) live CD into the CD-ROM drive.
First goto the folder “pool\main\d\dkms” in the CD-ROM and double click on the “dkms_2.1.1.2-5ubuntu1_all.deb”. It will take you to the synapatic packet manager, click on install button here.
Next goto the “pool\main\b\b43-fwcutter” in the CD-ROM and double click on “b43-fwcutter_013-3_i386.deb”. It will take you to the synapatic packet manager, click on install button here.
Next goto the folder “pool\restricted\b\bcmwl” in the CD-ROM and double click on the “bcmwl-kernel-source_5.100.82.38+bdcom-0ubuntu3_i386.deb”. It will take you to the synapatic packet manager, click on install button here.
Once this is done, restart the system and the wireless will work just fine ( click on the wireless tab on the top right hand side of the screen and select the network to connect to. If it is a secured connection then enter keyring token when prompted.)
Using this method other restricted drivers present in the CD-ROM can be installed provided the dependencies are taken care of (the dependencies programs are present in “pool\main” folder)
