Every day since monday around 8:38 PM PST I lose connection to whatever match I`m playing and I get booted from PSN. I then wait some minutes to sign back in, but it keeps occuring for awhile (Not sure how how long, usually go to sleep around 10). Any other time of the day it works perfectly. Also I`m playing Uncharted3 if that`s any help.
It's not the router, it happens during a specific time each day, the rest of the day I can play normally. It's not just a one time thing either, when I can sign back in I only played ofr a little while and it signs me out again. Also I think it only happens when I'm actually gaming online and not when I'm idling,
I can't stay connected to the PlayStation Network right now, so I think the servers are under maintenance. I haven't had any problems the other nights though.
edit: I just got back on, and it doesn't look like anyone on my friends list got disconnected. Who is your internet service provider?
