wc c3545 loosing network connection

[Goshe]

I have WC C3545 which when is coming back from power save mode to normal mode is not present in network. If it is restarted everything is ok and works normally till next power save and getting back. The customer have another c3545 and there is no such problem on it.
Any suggestions?

Check to see if there is a firmware upgrade available for the printer. What level is the printer at currently?
