Hi Shane,
Sorry to hear that rebooting the Hub did not clear up the issues with your signal levels.
Are you able to perform a Pinhole reset for me please?
Disconnect all unneeded ethernet cables from the rear of the Hub.
With the Hub Powered on use a paperclip or similar (I use a mobile phone SIM Slot tool) and do a pinhole reset.
Depress the pinhole switch for a timed 60 seconds then release.
DO NOT reboot the hub but allow it 5 to 10 minutes for it to boot itself up.
Please do let me know how things are working for you after this, thanks.
Serena
