I am trying to FIND out why the WIRELESS internet on my laptop is not working. After searching google I found these TWO commands lspci and lshw -c network. But I still can't find out why it won't connect.

When I use the lspci command it shows that it is detecting the wireless network card. Then when I enter the sudo lshw -C network command right after the password it says *-network DISABLED. I think this is why I am not able to access the internet. Could someone help me enable the connection? It is not encrypted.

Ubuntu DETECTED the physical hardware for the laptop's internal wireless card (atheros) but had no drivers to install for it.

I plugged in an Ativa brand wireless card to the PCMCIA slot of the laptop, and Ubuntu detected hardware and installed drivers for the Ativa card. (I forget what chipset/architecture the Ativa card was.)

Can you borrow or try another wireless card on your laptop to see if Ubuntu will detect and install drivers for it?Is the router set up with an SSID?
If so you will need to put it in your network settings so the laptop can tell the router it is allowed to access the network. I can see many routers on our wireless but all but one requires at minimum the SSID to be sent including my own.

Is your network adapter using Athros chipset? if so have you tried the MadWifi app? It's available in the Ubuntu repositories and hasworked wonders for a few of my friends who's wireless had similar problems.
