If this phenomenon occurs after connecting to the network,
there may be a loop between two Ethernet switching hubs
within the network, as explained below.
- There are two or more Ethernet switching hubs in a network.
- Two of the hubs are doubly connected by LAN cables.
- This double connection forms a loop between the two hubs.
Such a loop may have an adverse effect on the projector
as well as the other network devices.
Check the network connection and remove the loop by
disconnecting the LAN cables such that there is only one
connecting cable between two hubs.
