NOTE: The 5667 was discontinued long before Microsoft created Windows Vista or Windows 7 so the USB Software Drivers were only designed for Windows XP and older Operating Systems like Window 2000, Windows Millennium Edition, Windows 98 and Windows 95. There were no further updates to the 5667 USB Drivers. There is no known workaround for USB and if you do load the drivers in a newer Operating System, it is suggested you create a Restore Point first in case the USB Drivers damage Windows, but you can use a 10/100 Multi-Port Switch behind the 5667 to multiply the number of Ethernet Port connections that can be made. The 5667 Router version can then support up to 253 PCs on its Ethernet Port if you provide that many replicated ports using Multi-Port Switches.
