A few days ago, my PS3 stopped signing into my wifi for some reason.
I looked and the last system update for the PS3 came out last November, so it's not that.
I've re-checked all the settings and they should be correct, but it won't even obtain an IP address. Same router as before, too.
I've looked over Sony's official support website and their advice is the usual extremely basic and vague advice that most official support sites have. Obviously, none of it resolved the issue.
