So this might be a good time to ask.

I need a wireless bridge that runs from Ethernet, just as you have described that the Airport Express can do. I don't need it's other features so I'm wondering if there is a recommended product in a lower price category.

I have a DSL MODEM/Wireless Router serving my basement and the copper LAN but the wireless is severely weakened the next floor up by the radiant, metal fins that run all along the in-floor heating pipes in the floor.

I admit I have not yet researched this to death as I normally do, as having the house well wired keeps this logically as a side burner project. However, the geek in me is 'ashamed' that my wireless doesn't work on the main floor.

The times I have spontaneously thought about it while wandering in an electronics store, I have been hesitant to purchase as all they seem to carry are wireless 'routers' and it is not obvious from the packaging if they can be configured for a bridge mode.

Thanks all.
