I have a Linksys WRT54GL that I have upgraded using Tomato Firmware so now it supports WDS. I have a new 802n express. My router is in the basement and my internet signal is weak upstairs. I want to put the Express upstairs to boost the signal and connect a printer to the express so I can print wirelessly. Do I need to use WDS, ethernet bridging, etc? Also, the new firmware allows for Access Point+WDS, or just WDS...what is the difference? I hope this makes sense. Any ideas?
