I couldn't succesfully authenticate to any 802.1X network, e.g.,
ietf.1x ietf-a.1x or eduroam. That already worked two hours ago...

I'm able to authenticate to ietf-a.1x with ietf/ietf with no problem. I've checked our radius servers, and we're getting a regular stream of successful auths. This might be a client issue on your side (though, there's certainly the chance that we've got an issue hiding somewhere). When you have a moment, come by the Help Desk and we'll be glad to look more deeply at your issue.

Hi Jim, thanks for the quick response.
Right now it's working again. I had also problems with IPv6 connectivity (couldn't even ping the default router) and IPv4 (massive packet drops). However, everythings seems to work again right now, I also could reconnect to the ietf-a.1x network to where I'm attached right now. I didn't change anything on my side though...strange

How's your signal strength? I'm wondering if this is a RF-side issue. You're still in Congress I?

Replying to jim@…:

Seemed to be ok all the time. However, I was disassociated from the ietf-a.1x
and I'm experiencing problems right now again. Same for a colleague of mine.

I'm trying to locate your mac address on our network and do not currently see it.

Is 00:21:6a:71:cc:cc the correct mac address?

comment:7 Changed 9 years ago by bless@…

Yes, it is, but I was offline at the welcome reception, so pretty clear that you couldn't see the address :-)
We could resume this tomorrow...

So this morning everything worked quite nicely, no single disassociation.
Since noon, however, I was experiencing some problems in Congress Hall III.
It seems, that my client tries to re-authenticate which doesn't work properly.
I'm now in Vienna/Madrid? and right now everything works after initial problems.
It seems that my 801.x client needs a TLS failure to start over properly.
I'll attach a packet text dump where one may see the problem in more detail.
Not clear where cause of the problem is exactly, e.g., whether this is an implementation
or interoperability problem.
From the dump it is, however, obvious that the TLSv1 Change Cipher Spec message doesn't get a reply
from the AP.
