If it is normal, use a red light pen to test whether the cable is connected. When it's green and steady, everything is fine. However, when it blinks red or stays solid red, it signifies a Loss of Signal, a problem preventing your router from communicating. It's the ONT if it's the LOS (loss of signal) light that is lit Hub is orange light TBH, the LOS light being lit means the router lights are irrelevant, they must be in a fault status because the underlying network is in a fault condition. as you are posting on BT Consumer forum, presumably BT.
