HP Photosmart 7510 - Cannot ping printer; Is on network

[Pulsar9]

I am unable to print and scan to my printer. I cannot ping my printer but when I look at the wireless settings it has an IP address. I have tired pinging the printer from two different computers, one PC connected to the router via ethernet and one is a laptop connected wirelessly. The PC and the laptop can ping each other. I have tried the following:

- Running HP's Hardware diagnostics

- Running HP's Network diagnostics

 - Running HP's Software diagnostics

- All gave the result that they cannot connect to the printer.

- Soft rest of the printer

- Hard rest of the printer

- Checked for firmware updates

- This has been happening since last night and I have restarted my computer twice since then.

I have had the printer for 3 months and it has worked mostly without any problems. Anyone have any idea of what is wrong and how to fix it?

Thanks

Print a Wireless Nework Test from the front of the printer (Wireless menu).  Does it have a valid IP address (not 169.254.X.X or 0.0.0.0.)?

What router?

[Pulsar9]

Yes, it has a valid IP address. 192.168.1.20

My router is a Netgear WNR2000

OK, great, thanks for that.  I woud guess there is a software or firewall problem.  Download and run this utility: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=mp-104282-2&cc=us&dlc=en&lc=en...

What does it say?

I won't be able to run that utility until Thursday. I'm out of town right now. I know the problem is not a firewall problem though. The laptop that I tried to ping the printer on did not have the firewall enabled.

I fixed the problem. I restarted everything but the router and - go figure - that is what fixed the problem.

Thanks for your help.
