This is caused by a power arc/spike in the circuit that is caused when you flick the switch. If the Ethernet cabling runs close or across any power cabling at any point in the cable run, the momentary jump in power will cause a burst of electromagnetic interference (EMI) to occur. This affects the HDMI signal transmission over the extender. However, this is only for a fraction of a second and the connection is quickly re-established. Unfortunately there is no an easy fix for this problem other than re-routing the Ethernet cabling a sufficient distance away from the power cabling. This issue can also be caused by an ‘earth leak’ somewhere on the electrical circuit. A qualified electrician should be able to locate and repair the fault. Return to the top of the page.
