1. What does wireless have to do with the firewall? Are you talking about a firewall on the router? If so, jsut allow all outbound, no real reason to restrict outbound connectivity. Otherwise, provide full access for the IP address of your PS3. I'm sure that information is somewhere in your PS3 settings. Make it a static IP as well.
2. I'm not familiar with PSA-WPK for encryption/keys. I think I know what you meant, but I don't want to assume.
In general you have no wireless problems though, it is a router configuration issue.
1. I don't know what the wireless has to do with firewall. It was just a radio button that I turned off to make the PS3 connect. It and the radio for "allow anonymous internet requests." I would love to provide full access for my PS3 addy but I don't know what it is nor how to find it. I don't know how to make it a static IP either. Please explain.
2. I don't know what the security is WPA, WAP, WOP, Whopper..... Confusing to me. I don't run it on my wireless. I live out in the sticks, don't worry about the neighbors stealing.
I setting this up at my brother in laws house. He doesn't have a wireless problem. I get a 60% signal to the PS3. I know the pass key for the router. I can get everything set up, just don't know how to set the router up to allow the PS3 to connect all the time.. I have to turn off the firewall and to uncheck the box "allow anonymous internet request"
So basically, I think what I am asking for help with is:
Make the router accept the IP address of the PS3.
Keep the security intact that is currently installed(not my system, my brother in laws)
Be able to use the PS3 on the wireless home network without having to deactivate the router's security.
