Connector itself, due to the nature of the device, a software firewall like those commonly installed on Microsoft Windows computers hosting the Wi-Fi USB Connector will interfere with its operation. To alleviate this issue, the user must allow the software full access to the Internet, or manually specify acceptable port ranges to allow through the firewall; depending on how that particular firewall is configured. Unfortunately, some firewall products (like ZoneAlarm, and Windows Live OneCare) are incompatible with the Wi-Fi USB Connector software and must be either uninstalled or disabled, leaving the computer open to possible attack from external sources. The user's only option in this scenario is to risk connecting to the Internet unprotected or install a different firewall product. Network topology A common complaint from more advanced users is the complete lack of user-configurable options in the Wi-Fi USB Connector software and installer. For the novice user, this is seen as a much-welcomed advantage of the Wi-Fi USB Connector over a traditional wireless router, but for those users who wish to use the device in a more complicated network environment, it can be an insurmountable obstacle. For example, the Nintendo Wi-Fi USB Connector will cause an IP conflict if an existing network is using the 192.168.0.x or 192.168.1.x IP schemes, both common IP ranges used in consumer routers. Packaging The Nintendo Wi-Fi USB Connector includes a USB extension cable, a manual, and a software CD. It is recommended that the latest version of the Wi-Fi USB Connector software should be downloaded and installed rather than using the CD versions, as important updates have been made in the newer versions. Devices shipped with software driver versions below 1.05 are incompatible with Windows Vista until updated. Discontinuation While Nintendo has not stated a reason for the discontinuation of the device, manufacturers Buffalo Technology are reportedly no longer licensed to distribute it due to a successful recent lawsuit by the Australian Government's technology research agency CSIRO (Commonwealth Scientific and Industrial Research Organization). As a result, the company has been prevented from trading in any products adhering to the 802.11a/g standards in the US, including the Nintendo Wi-Fi USB connector. Nintendo, however, only states on their website that the device is discontinued and says that a standard wireless router should work with the Wii. Here is their official statement: "Please note: The Nintendo Wi-Fi USB Connector has been discontinued until further notice. As
