Powerline product question need wireless expansion

Hi, I have a Linksys Router (WRT54GS0) upstairs and signal is not strong enough downstairs in my house even with 14db antennas. I do not want to burn any new third party firmware in the router and adjust power output.

Note I did have a Linksys WRE54G wireless extender downstairs to amplify the signal but it was problematic and did not have a strong enough or consistent signal. It has since been tossed.

I would like to have wireless access downstairs for laptop use (will buy this year), and streaming audio to a stereo (via a Squeezebox unit I possess).

I would like to run a connection from my router upstairs to some sort of Powerline adapter upstairs.

--->>Then downstairs I would like to pick up the signal through the electrical system via another Powerline adapter BUT I want the signal to be wireless...

What is the best bet or choices/combinations of products to accomplish this?

I guess I could use Ethernet Powerline adapters on both end and perhaps plug in another AP but perhaps there is a better way to do this.

Thanks in advance for all suggestions... Patty
