Summary: Overall, the performance of this product is fine, but I'm giving it 4 stars because of a few issues: 1. It doesn't support WPA2 encryption. I had my home network set up using WPA2 and had to switch it to WPA in order to use this adapter. 2. In the case of the specific one I got, the MAC address printed on the outside of the adapter is NOT the real MAC address of the adapter.
