Hey guys

I have my PS3 set up for online use using a wirless router, the router is a Netgear DG834PN, when connect to the Playstation Network it is slow to log in, also when downloading demos, games etc. it is also quite slow, someone told to to make sure that UPnP is enabled on the modem which it is but according to the connection setting on the PS3 UPnP is not avalible, also the NAT is measured at NAT 3 on my PlayStation 3 despite, i would like to be able to get NAT 2,

Any ideas how i could do this?
