I have BT FTTP 150 installed and get decent speeds on a wifi speed test, circa 150 mbps.
I do however experience various severe latency issues with different applications over wifi: Using a web browser on Yahoo mail, it is extremely slow especially when trying to open an attachment; Disney Plus can’t connect and using Lichess, it periodically just disconnects. All of these applications work without issue over 4G and used to work with the previous FTTC broadband (albeit at slower speeds around 30 mbps). Wifi connects at 5Ghz and other applications seem to run without issue.
Anyone had a similar experience? Any ideas as to what I can try to resolve the issue?
