I get the error message: 21345 failed to open a connection to the device. Although the device is in the immediate vicinity of the router, the wifi connection is interrupted every now and then. I am using macOS Big Sur current version. I have tried everything, nothing seems to help. I never had such connection problems with my old hp printer. What is wrong???
