So I have my z100 upstairs in my house and Playstation 3 downstairs connected by wireless. The problem i'm having is the signal isn't very strong where it is. So I want to use my linksys WRT54G in the basement and have my playstation connect to it through the wireless. How would I set this up? My vision is cablemodem - Z100 - WRT54G. If I use the WRT54G will the devices conneted to it show up as one network object? I also have an WAP54G would that be better to use? Also how do I get around the nat problems i'm having with Playstation3?

Would upgrading to firmware 8.0.19EA solve the nat problems with Playstation 3? They have this option for Xbox. To host XBox LIVE games, XBox 360 requires gateways to use the "Open NAT" method rather than the normal "Strict method. You can modify the
Embedded NGX appliance to allow hosting XBox LIVE games on your XBox 360 console, by going to the Security > SmartDefense page and selecting Enabled in the XBox LIVE Open NAT drop down list.
