As complement to my recent post „RE: KDL-43W807C recording to HDD fails as TV set turns off before the program to be recorded” I search for an explanation in connection with point 2 of my 2nd post (app. TV Remote control for Sony TV version 9.4.47). Mobile phone can be connected to Bravia TV set under the above app. only if Wi-Fi network on the TV is set to static IP option. If Wi-Fi network is set to DHCP IP option, connection fails. At the same time, if Wi-Fi is set to static IP, connection to the (home) network is ok, but no internet. My knowledge in IT is very modest, so can anybody explain the the role of static or dynamic IP of a device in a wi-fi network? Why does the TV set indicate that connection ok, but no access to internet when static IP is set? A TV set is not so mobile as a phone or tablet to change the Wi-fi network. If I set a static IP, how to configure manually the connection (other parameters)? What should be the correct setting of Sony Bravia 2015 TV when connecting to home wi-fi network: static IP or DHCP IP?
