Re: [90attendees] iPhone wifi weirdness during the conference

[Chris Elliott <[e-mail]>]

We can't fix what we don't know about.

My iPhone5 worked reliably across all networks, except for ietf-hotel in my
room, but I was in a corner room at the very end of the hall. My laptop
even had issues there, despite the much better antenna. My Airport Express
solved that problem and gave me much better wifi performance in my room
using the room wired connection. Other folks I know had Androids of various
types and they also worked well on our networks.

Please report such issues when it happens--this meeting (and many others)
Verilan is contracted to support the network and staff the help desk.
Please make use of them, either in person or by submitting a report to
[e-mail], as noted in the Network Information page. It is
obviously too late now, unfortunately.

The information that would help us debug these issues include:

 - The model of device, the version of OS it is running, and the MAC
addresses you used on it's wifi interfaces
 - The SSID you are connecting to
 - The BSSID of the AP you attach to (MAC address of the AP)
 - Where this happened
 - Description of what didn't work, and, if other networks work, what did.
Include the v4 or v6 addresses and router and/or DNS addresses you got, or
which you didn't get.
 - If you are using the 802.1X encrypted networks (ietf.1x, ietf-a.1x, and
eduroam), exactly where it failed. Did you get authenticated? How do you
have your 802.1X supplicant (client) configured? Do you have our
certificate in your certificate store or are you asked to accept it? Are
you using ietf/ietf as username and password for the ietf*.1x nets? Are you
using TTLS or PEAP with MS-CHAPv2 or GTC inner EAP methods?
 - If you did get addresses, could you ping the router, DNS server? If so,
where couldn't you reach, and what does a traceroute show?

Don't worry if you can't supply all of the above. It's great if you can,
and we can help you find what we need if you can't. If you can only supply
some information, the MAC addresses you used on device's wifi interfaces is
the most important for us to start tracking down where things didn't work.
Often we can determine the issue and help you re-configure your devices in
minutes. It might take longer if it is a network issue, but we were only
affected by a single bug, and it did not affect any attendees, that we
configured a workaround for this time. We had no other problems that we
knew about.

Safe travels, and hope to see you in Hawaii!
Chris.
