Hi there,
You will find you LAN (BroadcomLAN driver 4.28) or (Broadcom Giga LAN driver 8.27.1) storage (Intel chip set driver) and Wireless (Broadcomm 802.11b+g wireless) or (Intel 802,11b+g Wireless LAN driver 9.0.1.9)  ->drivers from here:

Plz let me know how you go

SOURCE: wifi drivers problem

first check in your bios if the internal wifi card is enabled.
if it was not then your problem should be fixed by enabling it.

if it was enabled then try :

go to the compaq/hp website go to support and get the wifi driver for your model c700.
and reinstall the driver.

if this doesnt help pls add more info like what is not working is the wifi driver installed does the wifi card show up in the hardware propertys etc any info can help.

good luck

You should have re-installed the Driver for the Wireless Card, you can do that by going to Control Panel, than clicking on System and Maintenance, and than going to Back Up and Restore, go to Repair Windows using System Restore, you can re-install your Driver that way or go to www.hp.com and go to Support, enter your Model #, and you can re-download your Driver from there.
