[SOLVED] wired internet

Hi I'm new to Zorn but have used Various linux OS for 10 years Yesterday I downloaded Zorn with a wired connection . After setting Zorn up and doing all the updates I started using a wireless connection. Now I cant use the wired connection. It shows nothing. I have tried a couple of different cat5 cables and know they work. Perhaps I need to start my network card? However I don't know how. My internal wireless card doesn't work either (BCM4311) so I'm using a mini usb adapter. How can I get these both working? Mu laptop is Dell inspiron 1501
Any help would be appreciated
Thanks

Can you please post back the results of the following terminal commands?

lspci -nnk | grep -iA3 net
sudo rfkill list all

Thanks for responding Here is what came up;

Ok.
Lets try this.
Open terminal and post the following command:

sudo apt-get remove --purge bcmwl-kernel-source

Then from another computer that has internet, download from here the b43 drivers that will hopefully make your card work:
https://www.dropbox.com/s/n2tjz9jnj9xw5xb/b43.tar.gz
(I have uploaded it onto my ubuntu one account).
A file called b43.tar.gz will be downloaded.
As soon as it is downloaded, copy same on a data USB stick.
Then boot to your pc with Zorin OS.
Plug the data USB stick and paste the b43.tar.gz firmware file you downloaded into your home folder.
Right click on it and select "extract here". A new file will be created named "b43".
Open terminal (ctrl+alt+T) and write the following commands, the one after the other, pressing <enter> after each one:

sudo mkdir /lib/firmware/b43
sudo cp /home/$USER/b43/* /lib/firmware/b43
sudo modprobe -r b43
sudo modprobe b43

Wait 5-6 seconds and your wireless should start working. If it does, connect to it. Also check if your wired connection is working.

Tried it and nothing.

Thanks madvineger your a star. Tried what you said one more time and both network cards are up and running.
