Hi Alfie,
apologies for the delay - you are right, the issue was that i had selected Static for the IP of the router in the settings, not realising that this should have been left as DHCP.
works fine now thanks - also i upgraded to latest s/w and cloud services and these seem to be fine also.
I have another issue but i’ll raise that in another topic if i can’t find an answer.
many thanks
Marcus
