This started a little while after openreach replaced the power adapter which had failed.&nbsp; The Bt and openreach help pages suggest that there could be a problem with the router connection which I have checked, or the router itself. There does not appear to be noticeable loss in speed or service but it has become distraction.</P> Sun, 14 Feb 2021 12:03:29 GMT https://community.bt.com/t5/Archive-Staging/port1-light-constant-flashing-fbre-modem/m-p/2141593#M1212810 vikK 2021-02-14T12:03:29Z https://community.bt.com/t5/Archive-Staging/port1-light-constant-flashing-fbre-modem/m-p/2141601#M1212811 <P>Try unplugging the cable to your router, does the flashing stop&nbsp;<span class="lia-unicode-emoji" title=":rolling_on_the_floor_laughing:">🤣</span></P><P>The flashing light indicates an active connection and is normal, I suspect it's not so much that it's just started - more likely you've only just noticed it</P> Sun, 14 Feb 2021 12:31:01 GMT https://community.bt.com/t5/Archive-Staging/port1-light-constant-flashing-fbre-modem/m-p/2141601#M1212811 Les-Gibson 2021-02-14T12:31:01Z
