Question

I recently replaced an dead D-Link wireless router with their DIR-330 and now my HP All-in-one 3300 printer cannot be accessed from my desktop computer (wired to the DIR-330) when the printer is operating in "wireless" mode. (It works fine when the printer is connected by wire to the DIR-330. Ping doesn't work either. All Anti-Virus software has been removed. The Windows XP firewalls have been turned off.
