i am trying to configure a Ubuntu VM on a MacBook? using a hardwire ethernet connection to a switch. the VM is failing to get an IP address via DHCP>

on hilton 7th floor, in the 50s room numbers (across the atrium from
elevators), dhcp over the ietf-hotel ssid is quite slow and sometimes
fails, as experienced on an iphone7.

i did not notice if my laptop was slow to dhpc, but it did not fail and
connectivity has been reliable, albeit a little slow to Seattle,
129.250.47.99.  ping rtt bounces around quite a bit.  Likewise to
31.133.144.4 (first hop) and 31.130.231.250 (2nd).  signal quality
seems ok; ~60%.  I appear to bound to AP 24:c9:a1:ed:91:28 at 2.4.
afaict, this is the strongest in the vacinity.

fyi

Hi, I'm at the far end of the hackathon, at the table with switch SW-HACK5. I have a router wired in, which is expecting to see DHCPv6-PD. It sees IPv6, but not apparently DHCPv6. Surprisingly, it has an rfc1918 IPv4.

I heard that there might have been DHCPv6PD issues. In the meantime, I have a solution that I use in other less cool venues.
