Unfortunately, I do not have a sample of the device, but I have just ordered one that will be delivered in about one week. I would guess that there is some difference between the RTL8192CU and the RTL8188RU chips. I Cc'd the Realtek group that works on USB devices. Perhaps they have some info that will be useful. Given the difference in time between the US and Taiwan, I would not expect any answer until Monday. There are some changes that affect connection with an 802.11n network that are found in the latest kernels. I'm not sure they are in the one you are using. You can get the very latest by downloading and building the "bleeding edge" version of compat-wireless. Larry
