So not "I have exactly the same problem reported in this thread."

If you can connect via Control:Web the core is running and Sooloos Configuration will not help to fix the issue however it does highlight (as it can not detect the MC200) a potential LAN issue.

It sounds like it's more a problem with your LAN switch. What model / version is it?

Can you try powering off all you Sooloos kit, PCs, Macs and the router/switch. Then power up the router first and then the MC200 and then the PC and see if that works.
