You have to have the correct OS on your S30. Its not going to work with just a router hooked up to an internet connection. Wyse S class thin computers are optimized for Microsoft Terminal Server, Citrix XenApp, Citrix XenDesktop, and VMware View environments. Remember this device is for virtual desktops and apps. Here look at this location to download the latest firmware version. It may help.http://www.wyse.com/downloads
Since the S Class has reached the End Of Life stage and it's no longer supported, you may not be able to get a conversion kit.
