I have UPnP turned on on the home hub 5, I am on option 2 however I am constantly getting the PS3 showing it is not available.
I am connected via wi fi and did not have this issue with my other ISP.
Also my ps3 speedtest only shows 9mb download whereas I am actually getting 78mb on speedtest.net on my PC.
Any help appreciated.
To eliminate the possibility of wireless interference, see if the problem still occurs if you connect using a cable.
To start with go into the routers settings and turn off smart setup as that causes slow download speed with games consoles.
But NAT type 2 is totally normal on the ps3. It means your NAT is open.
As for the ps3 showing UPnP as unavailable thats a common bug with some brands of router but I think it shows as available for me and I have a home hub 5
