Looks like I will get the linksys WRT54GL. The "L" can use some 3rd party hardware that provides serious tweakability and can change attenae for range increase.
It has 4 ports, so I believe I can plug in my PC & MAC (they and the router will be in the home office) and use the wireless for the Wii two floors away. (Am I correct with this assumption?)
The 'L' stands for Linux and it does have some nifty tweaks, The antennas are replaceable. I added the high gain antennas to my G router and the PC cards, but I still had dead spots in my house, so I went for the new 'N' router with MIMO, it still works with B and G equipment but the MIMO technology works way better, no more dead spots and the signal strength is always strong. Not sure about being able to route the Mac through the same router as the PC.
