Unable to get wireless netgear WNDA3100v2 to work

After a long struggle I was able to successfully install the ndiswrapper and the windows driver. The driver is reported now as installed:

sudo ndiswrapper -l
bcmwlhigh6 : driver installed
    device (0846:9011) present

The device id matches the one from lsusb output:

lsusb|grep Net

Bus 002 Device 002: ID 0846:9011 NetGear, Inc. WNDA3100v2 802.11abgn [Broadcom BCM4323]

But still can't connect to wireless.

iwconfig
  eth0      no wireless extensions.
  lo        no wireless extensions.

I noticed that:

modprobe ndiswrapper

Returns nothing.

Then I did:
dmesg|grep ndis

And voila. What do those messages mean? Both my drivers and my ubuntu are x64.

I doubt that bcmwlhigh6 is correct for your device. I suggest you try the files from post #6 here: http://ubuntuforums.org/showthread.php?t=2052594
