Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Streaming 218 not visible on network anymore

Thanks for your help here.
I now have the "IP Control" app install on my:

iPad and the app is working.
The app found the "218 Musikzimmer" (my custom name for the 218) and the serial number one IP address "192.168.1.80".
BUT if I try to "connect manually" and enter the IP address manually on the next step fails "error message: "Connection failed..."

iPad and Mac
Try to get access over the web browser fails.
Scanning with IP scanner fails also with pings.

iPad
Manually added a new device on the IP-scanner >> open ports are found 554(rstp), 555(dsf) and 556(remotefs-rts, rsf, Brunhoff remote file system).

Try to access with IP 192.168.1.80:554 fails as 555 - but on 556 I get the message "Not allowed to use restricted network port".

Mac
The IP scanner asks for the "hardware address" not MAC address - how can I find it (no sticker anywhere)?

Still the router is in the cellar with one cable upstairs to my MacBook and the 218 is IN the cellar direct plugged in the router.

Either working with LAN or WLAN on MacBook give the same result, also power down MacBook and iPad.

So I need "a little help"...
Thanks Robert
