This is literally driving me nuts!! I have two of the WRT54G-TM routers with firmware version 5.00.33. I have one connected to my DSL router in the office downstairs and I would like to hook the other one up upstairs and have PC's and other devices that are plugged into it get internet access as well as LAN access to anything connected to the downstairs router. I've seen that it's possible on various websites, but none of the "how-to" explanations actually match up to what I'm seeing on my router settings. So I'm not sure if it's the firmware or something I'm just not seeing. Can anyone help?
