Fast Ethernet Connectivity The D-Link DUB-E100 is a high-speed USB 2.0 Fast Ethernet Adapter for Windows/Mac/Linux desktop and notebook PCs. It's an easy way to provide network connectivity without opening up your computer or filling a PCI or CardBus slot. Easy to Install, Easy to Use Set up the Fast Ethernet Adapter in minutes by installing drivers found on the supplied CD. Then connect the DUB-E100 to a PC's USB port on one end and to your network switch or router via the RJ-45 Ethernet port on the other end.
It is that simple to connect your computer to a wired Ethernet based network. Energy Saving Suspend / Resume Function The DUB-E100 supports USB energy saving suspend and resume functions to minimize power consumption, which is especially important for laptop users. Power is provided directly by the USB bus, eliminating the need for an external AC power adapter. Slim and Light For extra convenience, the USB connector on the DUB-E100 can be folded into the body. This compact and portable design makes it easy to fit the unit in a laptop bag.
On Windows 7 32-bit, you can get it working, but it takes some doing. First of all, the D-Link website doesn't offer Windows 7 drivers, but offers drivers for pretty much every older Windows OS. They also don't offer an installer.
So what you have to do in order to install a driver for an older OS is to go to the Device Manager, locate your DUB-E100 and press 'Update drivers'. From there, choose to update them manually, then tell it to search in the Windows 2003 x86 driver folder. Now you could install the Vista drivers, but they actually have serious issues - your internet connection will work, but you will get heavy data corruption, so any download would be a guaranteed failure, while webpages would display properly only after refreshing them several times. The Windows 2003 drivers work a lot better. I believe that the internet speed is slower with them, but at least you don't get data corruption. Also, in case you want to switch drivers, you have to uninstall the ones you have installed first, or the system will simply say that the drivers are already current. I also haven't tried the XP drivers yet.
