Need a Windows 7 Driver for an internal Broadcom BCM43222 4322 mini PCI 802 Wireless WIFI Card. is the 5.100.57.8 version listed above the file I need?

Acer: De ce paquet soutient les modèles suivants de conducteur: Carte réseau Broadcom 802.11b; Broadcom 802.11g Network Adapter; Carte réseau Broadcom 802.11a.

This package supports the following driver models:Broadcom 802

I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible.

From Acer: This package supports the following driver models: Broadcom 802.11b Network Adapter; Broadcom 802.11g Network Adapter; Broadcom 802.11a Network Adapter.

Tried a bunch of solutions. This one finally worked for my wireless router. Thanks!! It is a broadcom bcm 4311 but Acer lists it as a Acer InviLink 802.11b/g router.
