I agree with Štefan. Over WiFi movie starts ok for a half minute, then skipping begins. Over TV LAN too. If I connect over USB LAN it’s OK. I have 2Gbit connection and Speedtest over USB LAN is 985 Mbps. Over TV WiFi max. 240Mbps.
When I connect to WiFi and immediately check the connection speed it is 1200 Mbps, but in a very short time it drops to 720 Mbps, even signal is very storng, router is 2m far away. Router is FRITZ!Box 6660 Cable (2 x 2 Wi-Fi 6 with MIMO, 802.11ax, 160 MHz Wi-Fi channel bandwidth). Galaxy S23 Ultra near TV hold about 1500MBit WiFi/router speed, Speedtest shows about 900Mbps dl rate. So it’s definitely problem with TV WiFi card/driver. Maybe they limited the speed due to the possibility of the chipset overheating? Anyhow, it’s not ok for TV worth 2000€ (55OLED909) to have in 21st century 100Mbps LAN and so bad WiFi 6 speeds. My Nvidia Shield from 2017. have 1Gbps LAN, and suport EVERYTHING you put in. Except DV, but 2019. model suport even DV.
I didn’t receive new fw, but after update I’m sending mail to Philips support. We all should!
Someone might say, don’t upgrade the software, but that doesn’t make sense over a longer period of time, especially if the new version brings significant improvements.
