I'm not a n00b Current setup: I have the dual-band Basestation and an Airport Express to extend the range. I have a MBP and a Mac Mini(Mac Mini is connected to Airport Express due to range). Everything works fine and then one day I can't connect to my Mac Mini from my MBP on the same wifi network. The Mini will show up in Finder, but when I click, it can't connect. Everything is running latest updates and latest firmware versions. Running 10.6.3. Please help. Thanks!
