Window 7 home premium network problem

hello

i've just installed windows 7 on my pc unit and when i go to connect to my wireless network the system says that there are no networks availible, i have downloaded the lastest drivers for my wireless adpater and the system shows it to be installed properly but it still says there are no networks near by.

wireless adptar : tp-link tl-wn751nd

router: sky

any help with this would be most welcomed

Silly question: Is it switched on? (Always start with the basics)

yes
and the adapter is a pci card

Have you configured your Sky router settings correctly?

My HP Wireless Assistant is turned "off." I have followed various paths, such as Wireless Assistant, to turn it back on and can't. Can you help?
