I have a N3200Pro. It's operational and is broadcasting. The Thecus Setup Wizard is able to see the box. I can change Network Configuration & Password. In the devices list of the wizard I see the box with both the LAN & WAN IP addresses as well as the MAC address and Broadcast address. In the Network Configuration I've tried leaving Host name set to the default N3200Pro and changing it to something else. IP type is set to Fixed and the correct IP address is displayed. I have not specified a DNS Server because I shouldn't need to, I don't think.
When I attempt to access the device via the IP address I get a timeout error all the time. It worked fine on my old system (Win7). The new system is Win10. The OS version shouldn't matter because it's just trying to access an IP address.
