problem to connect a printer directly to a wireless router.

I purchased a network all-in-one pronter (brother mfc-5440cn http://welcome.solutions.brother.com...fc 5440cn_all)

I connect the printer directly to a wireless router (edimax br-6114wg) by an ethernet wire.

My computer is wireless connected to the same router and cannot detect the printer at all.

When I connect the computer to the router by an ethernet wire it detects the printer immediately.


I updated the router firmware, but it didn't help.

Any ideas?
Thanks!
