Hi Ilyas786
Thanks for posting and welcome to the community.
In relation to the hub, please do the below for me;
• Turn the power switch off on the back of the Hub.
• Ensure the Hub is upright, in a well-ventilated location and out of direct sunlight, if possible.
• Switch the hub back on at the power. The Hub should now operate normally.
I have also done a system check and there's no area issues, the levels are in spec but low. Can you make sure all connections are finger tight for me and then reboot the router?
Let me know if the above checks solves the red light.
Best wishes,
