Best you do it Ethernet connected to the hub as the first test!</P><P>&nbsp;</P><P><A href="https://www.thinkbroadband.com/speedtest" target="_blank">https://www.thinkbroadband.com/speedtest</A><BR /><A href="https://speed.cloudflare.com/" target="_blank">https://speed.cloudflare.com/</A><BR /><A href="https://www.waveform.com/tools/bufferbloat" target="_blank">https://www.waveform.com/tools/bufferbloat</A></P><P>&nbsp;</P><P>&nbsp;</P> Mon, 06 Oct 2025 11:59:51 GMT https://helpforum.sky.com/t5/Broadband/Broadband-performance/m-p/5107921#M522786 JimM1 2025-10-06T11:59:51Z
