I just set up my airport express attaching it to my router at home. Now i've tried it at work and i can connect to it but the computer isn't getting an IP. I plan to use the airport express when i travel, and only plan on having my ipad with me. I'm getting nervous that i'll need a laptop to set this up in each new hotel i'm in. Am i missing something? Is there a particular setting that will allow it to work without issue anywhere i go? Also, is there a setup app for the ipad or an ip i can browse to to setup?? Thanks everyone.
