I have both my PSP and PS3 up to date with the official firmwares (3.52 and 1.90 respectively) but I always get signed out of the PSN network and some error displays on my PS3. I reconfigured my router and have a NAT type of 2 thinking that this would help but it still signs out periodically. I thought that by selecting the "auto sign-in" checkbox, that if my connection were ever lost, it would try to reconnect. But it seems to only auto sign-in when the PS3 is first turned on. All of this makes remote play next to impossible since I can't be home to manually sign back in. Don't know if it's my PS3 or my router that's causing the disconnect. Any suggestions? :??
