Hello Martin
My router is a billion bipac 8800nl r2.
I've just changed the primary DNS to a different 'actual' DNS address so I'll see how that works out.
I know what you're saying about "is the issue with the router or with the Humax box?", but the way I'm looking at it is when some kind of gadget that connects to a network is sold I'd hope that it will work with any router, specially routers supplied by an ISP. I should imagine a very large percentage of users will be using the router that's sent to them by their ISP.
As GrahamRHK suggests above it's the ISP supplied routers that's most likely the cause of the problem.
anyway, fingers crossed the new DNS address works. I'll know tomorrow
Thanks for your help with this.
