Hi All,

Just been troubleshooting an unusual issue that is not really related to the normal items I get involved with, but I thought might be worth posting the details on to save everyone a lot of headaches if they run into it. 

For those with their Sony Playstation 3 (PS3) console connected to the local LAN (either wireless or wired), you may experience regular Internet drop outs while the PS3 is online.  The issue appears to be random, but it occurs approximately every 1/2 hour when the "right functions" are being used on the PS3.  The one I investigated worked without issue for long periods but it appears to depend on which games you are playing or functions in use.

From what I can diagnose, it appears that the "Media Server" search function causes some Internet routers (ADSL Routers) to reset at regular intervals as it searches for media servers on the LAN.  I suspect it is something related to uPNP or similar, but in simple terms you just need to TURN OFF the "Use Media Servers" function and the problem will go away.

Not sure what you can do if you need to use the media server functions, but I guess I will look into that when I need to use it.  If anyone has it working and knows another work-around please reply to this post.

Cheers,

Aaron (XR64T - For those online!)

Update - More Information

Hi everyone,

Just a quick update on this one, it appears that the Intrusion Prevention (IPS) settings are what is causing the issue.  It looks like the IPS settings on the router are shutting down the connection to block "unwanted" traffic.  Unfortunately, the "unwanted" traffic is simply the PS3 connecting to the Playstation Network (PSN).

So far, my experience is that a good majority of games work without issue, but some require additional traffic types which appear almost like peer to peer (P2P) traffic and this is what is setting off the IPS triggers.  An example that I have seen is with Burnout Paradise, the game works correctly when just using the "Burnout Store" but when you attempt challenges against other online users, the potential issue of Internet dropouts raises its head.

Still not sure of the true cause, but hopefully this gives some assistance in troubleshooting your own connectivity issues.

Cheers,

Aaron.
