I was on a wired xbox one connection and got the error. All I did was disconnect the wired connection and set up the wireless connection. I was back on immediately after hooking up to wireless. I have not tried to go back to the wired connection

I don't know too much about the subject, I'm just going to list some of my experiences. I got rid of the port filtering on my router, and now I can actually log on. Set up my NAT on my PS3 and router and confirmed it was type 2. I live on a base/dormitory/campus with a lot of modem/router combos around me from the same company. I changed my broadcast channel to something other than 1, and bumped up my MHz to 40 instead of 20. Set my DNS to some free servers and set up a permanent IP for my console. I'll try and keep an update on it for anyone who is interested. I've gotten almost every single error code, marionberry just today. After fiddling around with my settings I can sit on the screen without getting disco'ed now.

I have a PS4 and i shut it off< then rebooted. worked immediately
