I am trying to increase my router strength/help my connection. I am having a couple problems.
1. When I set my PS3 to have a static IP it registers as unknown to my router, if it assigns automatically it will register...why is this?

2. My router shows my signal strength at 20% more than my PS3 registers the signal...why???
3. Is there a firmware that works best with the PS3? Im at 1.9.
4. I know environment etc interfers with signal, but over the past couple days my signal strength has dropped about 15%, what would cause such a drastic drop all of a sudden?
5.What are the best settings for the PS3?
