HP Laserjet p1102w requires restart to restore wireless network

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

The printer's network card may be faulty. Talk to HP about it.  If it is still under warranty, get them to replace the card. If not, get a price and see whether it's better to repair or replace the printer.

Are you able to PING the printer when it no longer responds to print requests?

I can ping the printer for a short while after it stops responding to print requests.  Also, the printer only will respond to print requests for about 5 minutes, but remains ping-able for a few minutes more.

Then... the PING will be time-out??

Well, I get the standard timeout you get when a machine is off the net or down.

Try resetting the printer's wireless settings, as follows:

1. Turn the printer off.
2. Press and hold the wireless button and the cancel button, and then turn the printer on.
3. Hold the buttons until all the lights blink in unison, and then release the buttons.

hdhondt,

Thanks, but this procedure doesn't seem to have any beneficial effect.  Connectivity still only lasts for a few minutes.

Does the printer have a web portal for management? IF yes, when you have a difficulty to print, are you able to access the web portal??

et01267Author Commented:
The web portal is available for a short time after restart.  But soon I'm not even able to ping the printer, let alone access the web portal.

FYI

http://h30434.www3.hp.com/t5/Printer-networking-and-wireless/P1102W-not-connecting-wirelessly/m-p/392181/highlight/true

Basically,

1. Make sure the firmware is up to date. Software and firmware updates and installation instructions for this product are available at www.hp.com/support/ljp1100series.

2. Make sure the LED status of Control Panel is OK.

3. Make sure the product environment has no impacts on wireless communication. Move the product to a location where it can receive a steady signal from the wireless router or access point. Or you might need to move the wireless router or access point.

Otherwise, it might be a software bug or hardware failure. In this case, you need to call HP support. :(

Well, none of these suggestions fit my situation.  The printer detects the WiFI network, and is actually available for a short period of time, but then goes off the net and must be restarted.  The solution is to throw the thing away and get something else.

Not actually a solution, but there may not be a solution in this case.

The firmware update did not help the problem and I find it very difficult to believe that 4 of the same printer would all have faulty network cards.  Any other ideas folks?
