No internet coection

I lads i was helping a friend with his Fujitsu siemens xp pro laptop that was running so slow i think it was going backwards i couldn't do anything with it not even in safe mode,so i used the kaspersky rescue CD and it worked fine finding virus,worms,Trojans and adware then i used malwearbyts from a usb stick and found some more,PC is running quick smart now but for one thing i cant conect to the net the wireles not workin and when i try connect directly thrugh the cable its wont work.so i go to device manger and under Network adapters 11 are yellow so i try update them but no good,iuninstall and then reinstall i get the (found new hardwear wizard install the softwear automatically recommended)( a box pops up the file bcm4sbxp.sys' on broadcom 440x10/100 integrated controller install disc is needed,
type the path where the file is located and then click ok,

copy files from
ointergratednetworkcontrollerlan/lan/drivers/winxp browse

i press ok but noting happens

when i cancelle i get another box tht says cannot start hardwear
click finish

 

dont have disc

 

Not something like the network is built into the motherboard and has been turned off in the bios - like I found out recently.

 

ITS A FUJITSU SEIMENS AMILO
SER,YSAH125090,
THE LAPTOP WAS OREGINLY XP HOME NOW IV LOADED XP PRO AND SOUND is not working either
