Large capacity drives (tested with up to 1TB) can be used to greatly enhance your computer's storage/backup capabilities. The perfect solution for users who are on the road & need a simple way to create their own portable wireless LAN (WLAN), the Wi Fi enclosure enables you to turn a hardwired Internet connection into a wireless access point for networking laptops or netbooks or Personal Electronic Devices such as iPad tablets, iPhone, Android smartphones or devices. While connected, users can access data on the enclosed hard drive, making it easier & more secure to share files with multiple computers at the same time over FTP, SMB or a dedicated web interface. In Access Point Mode, the S2510U2WUKEU will act as a Wireless Access Point (WAP), enabling computers/smart phones/tablets to connect to it wirelessly. All connected clients will be able to access the data & resources on the S2510U2WUKEU. If the S2510U2WUKEU is connected directly to an Internet-enabled router/switch/broadband modem, all connected clients will have Internet access as well. In Client Mode, the S2510U2WUKEU will act as a wireless adapter for a host computer through a standard Ethernet port. This enables you to wirelessly connect to an existing Wireless Access Point (WAP), while having access to the data & resources on the S2510U2WUKEU.
