Question : Problem: wrt54g connected to wap54g

There was a question about getting these to work together. Can a desktop be connected to the ethernet port on the ap where it is located?

Answer : Problem: wrt54g connected to wap54g

Do you mean like this

      [ WRT54G ] ........ [ Desktop ] -------- [ WAP54G ] )))(((  [ Wireless Computers ]

Why do want to do like this?

The better option would be to connect WAP54G directly to the WRT54G Router to it's LAN Port.

Having said that, the above configuration would work provided that the Desktop is configure for Bridging or ICS.
