Vista - New PC, Having trouble with wireless

ok i just brought a new intel pc, the S-Series.
with no operating system, atm has a trail of wondows vista, (im getting a real copie very soon)

anyhoo, when i use the Ethernet Cable directly from my pc into the modem works fine.
BUT
when im not using it and using wireless and trying to search for any wireless rounters around, i cannot find none, i got a wireless card i think its:
Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.0), the 2008 version, theres a 2009 version (update), but every site i go to download they try and rip you off in buying membership and download it!

so round it down
cant find any routers when using wireless, cant find any FREE non riped off updates for my wireless card.. pheraps its not the card, and somthing else, and no no FIREWALL is blocking it.

thanks need super help..

what type of router are you using some routers do not work well if there not same brand,for your wireless card i would either buy a new one or return it if its still under warrenty

your wireless card may not be the only problem is your laptop compatible with wireless?

no, it dosent find any wireless not even neighbours and its a pc not laptop

i need to install the driver for the wireless i think or update it.

cause it can search for the wireless but dosent locate any, it has a wireless card cause i can search for wireless routers, but its not installed i dont think. the driver.

your desktop PC is scaning for wireless networks but it cant locate any?
either your wireless card is a dud or the wireless networks are hidden other than that
i would buy a wireless card that is the same brand as your router
