Have a HP Laserjet p1102w connected via wireless. It is configured with DHCP, and the 801.11g network is secured via WPA2 and MAC address restriction. The printer will print fine immediately after restart, but after some time of inactivity (maybe an hour or less) it will no longer respond on the network and must be restarted in order to print again.
The printer is configured to never go into power save mode.
What needs to happen for this damn thing to keep its network alive?
For what it's worth, I'm accessing the printer via Bonjour on a Mac, but when it loses the network I'm unable to reach the builtin web server or ping the device.
The firmware datecode is 20100223
