If this issue occurs after connecting to the network, there 
may be a loop between two Ethernet switching hubs 
within the network.
-  Two or more Ethernet switching hubs are 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

Check the network connection and remove the loop by 
disconnecting the LAN cables such that there is only one 
connecting cable between two hubs.
