I used to have only an airport express in my apt which worked great, both with printing and itunes, no issues at all. We then moved and during the move, i bought a new extreme to get faster/wider coverage and use the express as a relay (and have printer hooked up to extreme and stereo hooked up to express in another room). Since installing the extreme, i cannot set up the express -- my MBP will not recognize it, even when hooked up directly via ethernet cable. Any ideas why this happens/what i can do to fix it? Thanks.
