So I purchased this little USB wifi adapter http://www.amazon.com/gp/product/B00762YNMG.
It works well in Windows 7, installed the driver and was good to go.
OS X (mountain lion specifically) was a bit of a different story. Plugged it in, network preference pane showed nothing. Installed the driver package on the included CD and it installed some
RA Link tool bar utility (grrr) that did did my wifi but I noticed in the network preference pane it has the same icon as the ethernet adapter - not the wifi icon.
Anyone have any experience with this and can enlighten me? Ideally I'd like it to act just like an Apple made wifi adapter without 3rd party utilities running all the time.
