Hi,

I have had fine connections since Saturday night in the lobby bar on ietf62
SSID.   But only in the lobby bar.

I haven't had connectivity upstairs on L3 expect a brief session this morning
where it came and went frequently.

I left Salon D at 5.40pm having had no connection all session.   I had
association, though the AP would drop periodically, and an IPv4 and IPv6
address, but could not see the IPv4 or IPv6 router with ping, i.e. 
130.129.128.1 for IPv4.

My mac is ether 00:0a:95:f4:c4:82.

I think my IPs have been  130.129.134.24 (which is working now in the 
lobby although it didn't work on L3) and 130.129.135.233 earlier.

I notice the problems significantly as an ssh punter.

BTW can't join ietf62-ipv6 at all, but see IPv6 on the ietf62 SSID.

Hoping for better in dnsop tonight :)

Tim
