After my personal tests:
- attwifi with 4E:53:50:4F:4F:XX is now working on 9.0 but it requires No Encryption.
- attwifi is no longer recognized as a Nintendo Zone in 9.0.
- 9.0 users & 8.1 users cannot tag their StreetPass data each other via attwifi.
- Change attwifi into NZ@McD1 then all the above shorts on 9.0 solved. But this also means (1) many tags from worldwide will flood into the German Nintendo Zones (2) Nintendo will pay more attention to NZ@McD1 than attwifi - Personally I think attwifi getting banned on 9.0 is intentional.
