[quote name='Methadon']Signout problems and slow transfers are signs of a port forwarding problem. Often uPnP doesn't automatically take care of everything, it just allows the connection to have an easier time being made. For an optimum PSN experience, you really want to assign a static IP and set up port forwarding. You can take care of this in 5-10 minutes by doing the following:
Log into your router, and first assign a static IP to your PS3. Your network will most likely assign everything "192.168.1.X" where X is the number unique to a device. Your router should say what the range of the value is. We'll come back to this.
Next, open a command prompt (xp/vista: start->run->cmd), and type
Open a new browser window and type 'http://X.X.X.X', where the X's are the numbers you got by 'Default Gateway' in 'ipconfig'. Under your 'basic setup' stuff, you should see the starting IP address for your network. Go ahead an choose a random number for your PS3 based off that.
Now goto your PS3 and edit your connection settings. Under IP, choose 'Manual', and enter your IP's prefix (the first 3 sets of numbers), and the number you chose for your PS3. For this example, let's say 134 is the value, so your IP would read:
Enter the values for 'Subnet Mask' and 'Default Gateway' that you got from 'ipconfig' in the PS3's network screen. You probably will have 2 or 3 DNS numbers provided from your router's 'status' page, which is where you get those values from.
Next, go back to your router's page and under port forwarding, open the following:
Code:
10070-10080 TCP
80-80 TCP
50000-50000 UDP
6000-7000 UDP
10070-10080 UDP
Save everything and power cycle both the router and the PS3. You should be ready to go. Open your PS3's browser and goto speedtest.net or something and see how your speeds check out.
You may also want to set a WEP or WPA2 password if you're using wireless, to ensure nobody else is jacking your bandwidth.[/quote]
