Best bet is running it threw your laptop first
Sprint card > Laptop > Ps3
This could be done with Internet Connection Sharing (ICS). There are numerous articles around the web telling how to turn this on in your laptop. This will then let your computer act as a gateway for the PS3's net access. Then just connect the PS3 via ethernet to your laptop (if you don't have a normal wifi card in there) and go through the network connection set up in Network Settings on the PS3.
