Disklavier

I have had the new disklavier control unit, dkc-850, for a while now and have not had any trouble connecting to the internet, from the start.

Now I have tried it last night and this morning and get the following error messages (I have pinged and it responds affirmatively):

Connecting to the Internet

Failed to connect
Analysing network

Failed to connect (2010)
Cannot connect to server

Please wait
16 27

Can anyone help?

Thanks,
George
