I don't have that Netgear part but the TP-Link TL-WDN3200. At first I 
had to compile the driver supplied by Ralink, but meanwhile it is 
supported by the standard kernel. But for 12.04 you would need one of 
the backport kernels; I used the linux-generic-lts-saucy package.

driver (see e.g.

I don't have a 12.04 machine left with the saucy backports kernel, so I 
can't check if that kernel supports the device. But you could install 
that package and then check with this command:

modinfo rt2800usb|grep v0846p9012

If output is something like this

alias:          usb:v0846p9012d*dc*dsc*dp*ic*isc*ip*in*

then the WNDA4100 is supported. However if it isn't supported yet, the 
kernel of 14.04 supports it - so maybe this is a reason to upgrade. :)
