Checked speed each day and despite being told no problems has failed to reach minimum 700 speed at any time. Anything between 400 to 600. Does BT monitor and take action or should I do something?</P> Sun, 14 Jun 2026 08:27:40 GMT cinnamoncottage 2026-06-14T08:27:40Z https://community.bt.com/t5/Home-setup-Wi-Fi-network/Slow-Full-Fibre/m-p/2464382#M218189 <P>Had full fibre 900 installed 5 days ago.

If you’re attempting to run speed tests to your WiFi devices using WiFi rather than using a Ethernet cable, it’s likely you will not see the 900mbps speed to many WiFi only enabled devices.</P> Sun, 14 Jun 2026 09:18:56 GMT https://community.bt.com/t5/Home-setup-Wi-Fi-network/Slow-Full-Fibre/m-p/2464387#M218191 Kimberlin 2026-06-14T09:18:56Z
