Solid red power light on Hub 3

[mazj_uk]

We have had a solid red light on our Hub 3 for the past 6 days. 

No area faults identified.

Several pinhole resets done.

Hub not overheating but turned off for 45 minutes and restarted as cold. Hub has plenty of ventilation.

No issue with internet speed. 5ghz signal is consistent, 2.4ghz signal drops out a few times a days. 

Turned off 2.4ghz signal and restarted. Turned into modem mode and restarted. 

Checked all cabling.

Spoken to a Faults Advisor for 45 minutes on the phone, various checks and reboots done. Still solid red light and advised nothing more to be done, monitor for 24 hours. 

Any help as to the cause and fix of the red light would be much appreciated.

Hi @mazj_uk,

Welcome to our community forums and thank you for your first posts.

Sorry to hear you are having issues with the red light on your hub. We can understand you concern and want to do our best to help. 

How long has this light issue been ongoing? Are you experiencing other issues with your Hub? Does this affect you use of broadband or WIFI?

Thanks,

[nodrogd]

Irrespective of the hub data, if the hub is displaying a red power light & is not being used in modem mode then the issue needs to be resolved for safety reasons. False positive indications are dangerous as they can mask a real overheat fault, which is a fire risk.

I will escalate this thread for a priority response.

[mazj_uk]

As per above the light has been solid red for 6 days, we have no issue with our speed. 5ghz signal is fine, 2.4ghz signal drops a couple of times a day.
