Note to other p727 users. The ethernet/LAN port on the TV is only 100Mbps, confirmed via the link provided, and the tests I was forced to conduct to resolve my issue.
I usually connect my internet TV's wired directly to the router, for faster and more reliable connections. However, when I upgraded my internet connection to 200Mbps a few months ago, I could not go past my old plan of 100Mbps using a speedtest app installed on the TV. I thought all the while that Globe has not yet activated my request for upgrade. They even came in an replaced the router with a new one, and it still did not get fixed. When tested using a mobile however, I can go up to 250Mbps peak.
It occurred to me later to change the settings from wired to wireless. Speedtest can now go full >200Mbps.
Counter-intuitive, but wireless is faster than wired, for my particular predicament.
HTH.
