I keep getting these constantly in the last week, wondering if this is a server side issue or on my end..
Normally this is never an issue for me, just started in the last week. None of my settings have been changed, other than switching from wired to wireless a few days AFTER this started, but my ps3 has been wireless before without this problem.
My ps3 is also set on DMZ, nat type 2, if that helps.
(Meant to post this on PS home support. Not sure how to delete it now -_-)
