Playstation 3 question - I put in a new wireless router today...my 2nd computer works fine?

May be...

but the ps3 gives an error of 80130319. any ideas what I need to do ?

The PS3 needs a lot of info from the router, so turn off everything that uses internet and then try again.

Reset the router. After it's all up and running again try having the ps3 get the internet settings again.
