I'm thinking about getting another airport express to extend my airport express network. The Express I have right now is in my basement, I have all my computers on the first floor (don't ask how the DSL modem ended up in the basement). If I put an airport express in between the computers and the router and set the express the repeater mode, will I lose thoroughput? If so, is it significant? Would it just be better to move the express I have now closer to my computers? Note: If I move the express I have right now, I would need to call my DSL provider and pay a technician to come over and move the DSL line closer to my computers.
