we have a laptop (Dell Inspiron 6400) that I cannot get hooked to internet. I am told that we need wifi USB and card.
Okay - I have here a Linksys wireless G USB network adapter 2.4 GHZ
and now what kind of card do I need?
Or do I need both in order to hook to internet?
It's a mini internal wireless card. Assuming the laptop is running Vista, when you click 'Start' and 'Connect to' if it's not shown then you don't have one. You should be able to plug in the USB adapter to connect wirelessly, but need to install the driver first.
Also check the internal is present but not switched on... http://support.euro.dell.com/support/topics/global.aspx...
