Cant detect wireless printer

Very frustrated.

Macbook Pro OSX 10.6.5
Canon MX870
Linksys wrt54g router

The printer finds the network. It says the connection is active - and if I unplug the router that changes to inactive, and back to active when I plug back in. So I feel the printer - router connection is OK.

The computer finds the network fine - evidenced by the fact that I'm wirelessly on the internet now.

The setup software tells me the printer can't be detected. I've played with a few of the alphabet soup of settings on the router page - but none seem to have any effect.

Would greatly appreciate any guidance.

Thanks

For anyone else with this problem:

After reseting the printer system click add a printer and select the MX870. It also shows up as a bonjour scanner. I just selected the printer first and it worked fine. Suspected I might not be able to scan if I didn't select the scanner as well so I did that too. I don't have time to try and scan something but the printer still works wirelessly.

Hope that helps someone.
