I'm *trying* for my brother's PS3 and he can't get WMP11 - so that's out. The problem is with DNS, IP and all those other computer stuff. This thing is more difficult than the Xbox to get online!
I even tried manually setting everything on the PS3 side, but the issue I get then is 'default router' It seems I NEED a value in their to conitue, and he doesn't have a router (USB wireless dongle direct to PS3). Also got TVersity but it picks up nothing.
The closest I've got when playing with settings, are finding the WLAN and resolving IP, but not DNS.
