Description

Hello,

I'm sitting in the back corner of the room. When joining ietf-a I see:

When joining ietf, I see:

(destination is in Germany, ~20ms is not bad.)

I'm using a Mac Air, OSX 10.9.2, ifconfig at the moment is:

The meetings in Plaza C and Buckingham have far more attendees in them they we were prepared to support. We'll be deploying 3 additional WAP's in these rooms during the first break which should mitigate the issues you are having.

Apologies and thank you for your patience.

We've augmented the number of APs and adjusted the power and believe that the rooms on -3 now should have decent IETF wifi. If you're going to be down there soon and can confirm this for us, please do so. If you're not expecting to be down there anytime soon, let us know and we'll close out this ticket.

Thanks!

Hi,

I don't plan to go back there for a while, so I'll not be able to check/confirm.

Regards,
Robert

Ok, thanks ... we've sent folks down to test, and it's been good, so we'll close out this ticket.

Thanks for letting us know!
