NETGEAR WG311v3 80211g 54Mbps Wireless PCI Adapter Is This Compatible With backtrack4???
After research, it would seem that the Netgear WG311v3 is using a totally different chipset than the v1 and v2.
The Netgear WG311 comes in four different versions – WG311v1, Wg311v2, WG311v3, and WG311T. v1 and T are both Atheros chipsets and are compatible out of the box. v2 is Texas Instruments chipset. v3 is Marvel chipset and not supported.
I've not seen it on Backtrack's compatibility list either so i'd say no, it's not compatible sorry pal.
