Liksys WVC 200 doesen't transmit video on WiFi.

I can setup camera when connected by wire, but after I try to run it on WiFi there is no picture and sound. The camera connects to the wireless network and gets IP (DHCP), but monitoring software doesn't see the camera and it's imposibille to connect to it by typing IP in the browser window. The network name and key are ok for sure. I use router Liksys WRT610N, set for DHCP with specitic IP reservation for WVC200.
