The issue is that the computers on the network regularly lose connection to the printer. The ip address cannot be pinged successfully.
the printer's network connection is solid, as are any devices joining the network.
These statements are mutually exclusive.
If you periodically cannot ping a given device on the network then at least one device's network connection is not solid.
Is it a wireless printer? Is there an option to connect the printer to the switch / router using physical RJ45 connection - at least for a test period?
Why does the printer have an internet connection?
