This is mostly a post-IETF poll to see if others saw similar issues.  Wifi on my laptop (Mac) worked fine throughout the conference.  My iphone on the other hand, seemed to have all sorts of issues with the wifi:
- "ietf" would connect most of the time, but not always give me an address.  Occasionally I'd get ipv6 dns address.
- "ietf-hotel" would connect most regularly, especially in my room but connectivity to the outside world was flakey at best.
- The ietf-a, and all .1x networks simply gave up immediately and fell back to the other config.

Mostly I solved my issues by disabling the wifi and falling back to Rogers.

Did anyone else see similar issues?  

In the future, what sort of troubleshooting is good for diagnosing the root cause of such problems?
