Thanks for all the ideas!
crablab,
Two of the wireless gadgets work fine - one of the panas and a Sky gadget. So I know it can work....But I will try to move the Sony to one of the places with a Pana, that I know works. That will reduce the possibilities.
Track Jitter,
Yes, it's a BT 3. BT claim that their 5 is better, so I might investigate that. However, my home speed is about 45mbps and it allows streaming on one of the tvs and 2 ipads all at the same time. The wifi-rate at the ipads, well away from the home hub, is over 20mbps.
MG23,
The Humax has all the right numbers..................but it has stopped linking to some of the internet now. It won't work apps, but will allow me to watch progs from earlier. Both need internet access!!
The Sony just says it is connected. I'm not sure it has the right numbers. I think a physical move from non-working locations to known working locations is my next step.
Thanks all,
AO
