Answer #1
Sounds like you need to re-install the drivers for your wi-fi and LAN card. Get them from the Toshiba site, or the manufacturers site. There should be a sticker on the bottom of the lappy telling you the brand/model number of the wi-fi card.
You can also check they are not disabled in Device Manager. (start > devmgmt.msc)
