Not being a broadband customer with Now TV all I can do is provide basic advice.
Have you tried to reboot the router? Like unplugging it for a few minutes?
Same could be done with the Sony TV.
Worst case you can give the broadband team a call as it is effecting all apps on the TV and not just Now TV.
