Clicking Smarthub 2 since migration to full fibre

[DrMagical]

Migrated to full fibre, engineer fitted it yesterday. Same BT Smarthub 2 that was fine until yesterday. Now it clicks all the time every 2-3 seconds. Quiet click but still annoying. Not overheating.

Any ideas?

Have you tried powering it off for a couple of minutes and then restarting it?
