Driver Ethernet Controller Pci Ven8086

Yet, I haven't been able to find out what driver I need for the device name as Network controller (PCI VEN8086&DEV_08B2). I have tried with most of the network related drivers from the Lenovo web site.

Dell vostro 1520 mass storage controller driver windows 7. I have formatted my HDD and tried to reinstall win 7 home pro (64 bit) and it has all reinstalled except my ability to network. The following devices show up in the device manager with warning triangles under 'other devices' -Ethernet Controller -Network Controller -Universal Serial Bus (USB) Controller I'm stumped because normally I'd use the driver toolkit to download missing drivers, but without these devices I don't seem able to connect to wireless or LAN cable. I've tried some of the drivers on the hp website but I keep getting errors telling me I have the wrong OS etc. Trial and error is getting nowhere. Device ID for ethernet controller is PCI VEN_8086&DEV_1502&SUBSYS_179B103C&REV_04 Device ID for Network controller is PCI VEN_8086&DEV_422B&SUBSYS_11018086&REV_3E.
