I had this very same problem but I was able to fix this.
My Setup PS3 80gb On Wireless (firmware 2.10)
Wireless Router: WRT54GS
My issue I had exactly:
When Searching for a Media Server on my Playstation 3 (or even having it enabled) would cause my PC to disconnect then reconnect to the router/internet. This is very odd, it was like the PS3 was taking full control of the router. After reading the forums and doing things each member sujested. I came up with a solution that works for the time being.
The Steps I did to get Media Server Working without disconnecting me from PSN and Disconnecting my PC from the internet.
- PS3 is on Wireless I assigned it an IP, And the DNS Servers. I let the PS3 auto setup the wireless then I took note of what it found for an IP/DNS servers and entered them in manualy and I disabled UPnP.
- I added Port Forwarding for the PS3 on its new assigned IP. (Ports: 80(TCP), 443(TCP),5223(TCP), 3478(UDP), 3479(UDP), 3658(UDP))
- Installed TVersity , (Also used Nero HomeMedia) Both worked. PS3 was able to find my PC running the server.
But every time I did a search or access the media server it would disconnect me from PSN, and my PC. SO we have one more step.
I found this after talking with some networking admins at work and friends.
4. Log into your WRT54GS Router and go to (Administration -> UPnP check disable).
They mentioned with UPnP enabled the router could be reset by the PS3. What is UPnP used for (Used by certain programs to automatically open ports for communication.)
Now I have my network all setup and what ports I want open for my PC etc.. so having UPnP disabled really doesn't effect me. But it could you, so if you have problems getting programs working on the internet this may not work for you.
But this is the solution I found to work for me.
I can use the Media Server on my PS3 without it disconnecting me from PSN or Disconnecting my PC. The Media Server ability was a very large reason I wanted/bought my PS3.
Hope this helps others.
Im trying to take caure of this issue right now. But I dont know how to assign an IP address. PRetty much steps 1 and 2 I have no idea how to do. :-/
Hey guys, i just recently bought a game called "Borderlands" and it asked me to download something so i can play online, when i tried to download it a message popped up in the top right corner of my tv saying " The PS3 has been disconnected from the media server". I tried disabling the UPnP then reenabling it and it didn't work. Any help would be nice, i already read the forum so please don't tell me to do that, i don't understand most of whats beening said anyways.
