Hello all, I've been getting this error code for about a month in a half or more. It started when I bought BF3 and was installing it and it hasn't gone away. I can't stay online for more then a half hour. Sometimes I'm online all night, but the next day it's back. I'm not very good with networking and to the best of my ability and knowledge have put the ps3 into DMZ and attempted to port forward. The issue has not been fixed. Infact I just got logged out again right now and it was about 5 minutes tops.
I have a belkin N300 Surf, I occasionally would get this problem and it would be gone the next day. It's been over a month now.
Should I look into a new router or ps3?
I've had a similar problem, see http://community.us.playstation.com/message/36464335#36464335
I think it had to do with my actual user, I performed the following tests to better understand the cause of the problem. It is best to do at a point where you are experiencing the disconnects.
You want to identify if the problem is in your Internet, router, user or particular game.
1. Connect your ps3 directly to the modem and see if the problem occurs. If so it may be an issue with your router.
2. If you get disconnects connected to your modem, try switching to a different game. If you have issues with BF3, i suggest another shooter to simulate similar networking needs.
3. Try to log on as a different user and play BF3 and see if you get the issue.
My issue had something to do with my user. I was also unable to delete anyone from my friend list. Currently, after I logged on as a different user, everything went back to normal.
Do you have anything else connected to the router as well? Like laptops? Desktops? etc. If you do, I have had the same problem before where one or the other was using the SAME IP address. I had to go into the Internet settings and manually change the IP address. Also try these settings as well, they work like a charm for me:
Proxy Server: Off
I used these settings and like I said, I havent had any problems since!
