having trouble watching tv on demand on smart tv with wired connection to fibre broadband. Takes ages I load, loads of buffering then eventually gives up. Works fine if hook smart tv up to 4g. Also can stream HD films via Apple TV with wired connection to broadband. Talk talk saying they can’t do anything because we don’t have talk talk tv but it seems to me that it must be an issue with broadband if tv on demand on smart tv works fine when connected via 4g. Speeds generally around 32 but sometimes drops to teens.
