Yes I have Ethernet plug ins one on humax other on router.The Foxsat is on hdmi
I player is no longer supported on a Foxsat-HDR (since 2016) when the BBC stopped supporting MHEG.
Unless your TV is new enough to support the newer Iplayer system as I said you need a more modern device. The Now-TV stick is likely the cheapest option.
That’s why you need a more modern device like the one I linked to.
If you have a smartphone or tablet then a Chromecast dongle is another cheap option to getting all the catch up and online TV services like iPlayer and Netflix etc.
