Here's the setup... Basement has a wireless router (serves as the firewall and DHCP server) with a wired switch/hub connected to it. The switch/hub used to be the Wired Router/DHCP server but I configured it to just be a wired switch/hub (static IP, etc.) once I added the wireless router. The wireless serves me very well for a connection in the basement or first floor. The wired switch/hub supplies my cat5 network in the basement and 2nd floor. Now the situation.... Son is home from college and brings his laptop. He wants to connect to the wireless from his bedroom (2nd floor) which also contains a wired desktop. Our other son has a wireless desktop in his bedroom (also 2nd floor). Reception on the 2nd floor from the basement is obviously poor with the wireless router in the basement. To address the situation, I bought (at what I felt was a great price) a WRT54GX. After thinking about it, I decided I would use this as an Access Point on the 2nd floor to improve reception. I have read a few posts on configuring the WRT54GX as an Access Point and it seems pretty straight forward - especially since I cut my teeth on such a configuration when I made the wired router a switch/hub. I plan on putting the WRT54GX in my son's room with the wired desktop. I will take the wired connection from the desktop and put it in a LAN port on the WRT54GX (after it is configured as an Access Point). I think I read somewhere that the WRT54GX doesn't require a crossover wire that it has auto-detection. My assumption is now that his wireless laptop and my other son's wireless desktop should now have excellent reception. My original wireless router in the basement will feed my basement and first floor wireless needs while the WRT54GX (Access Point) will serve the 2nd floor's wireless needs. All this and now comes my question! Can I use another LAN port on the WRT54GX (Access Point) to feed the wired desktop (in the college son's bedroom on the 2nd floor) too? Basically turning it into an Access Point and Switch/hub. Any insight/experiences (from any of this configuration) would be greatly appreciated!
