Network Controller/PCI Simple Communications Controller

Hi,

 I am unable to connect to the WIFI Network through my Laptop Dell VOSTRO 1440 ( Service Tag -  <ADMIN NOTE: Service tag removed per privacy policy>) using WIN 7 (64 Bit)

I am able to see 2 issues in drivers in the Other Devices Section in Device Manager

1. Network Controller Properties -( PCI\VEN_14E4&DEV_4727&SUBSYS_00121028&REV_01\4&7427AB5&0&00E1 )

2. PCI Simple Communications Controller - (PCI\VEN_8086&DEV_3B64&SUBSYS_051C1028&REV_06\3&11583659&0&B0)



Can you please guide us here ASAP regarding the specific drivers that we should download in order to resolve this issue ?
