#1339 fixed intermittent failure to receive functional DHCP lease on ietf-hotel in swissotel guest room Sean Croghan kaduk@…
Description
Hi all,

This morning (Sun 17 Nov 2019 12:57:28 PM PST) in the swissotel guest
rooms, on ssid 'ietf-hotel' I find my debian system reporting that I am
successfully associated but my tools report that I only get ipv6 service:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
kaduk@prolepsis:~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
122: wlp58s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 30:52:cb:e7:7c:45 brd ff:ff:ff:ff:ff:ff

    inet6 fe80::95ba:c96b:d420:7871/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
kaduk@prolepsis:~$ ping6 www.google.com
ping6: www.google.com: Temporary failure in name resolution
kaduk@prolepsis:~$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 2001:67c:370:229::7
nameserver 2001:67c:370:229::6
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

And even that doesn't help me very much, as the name-resolution failure
from ping6 indicates..

Using the software rfkill to stop/restart the wireless connection and try
again, however, does get me ipv4 service:

kaduk@prolepsis:~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
122: wlp58s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 30:52:cb:e7:7c:45 brd ff:ff:ff:ff:ff:ff
    inet 31.133.157.178/20 brd 31.133.159.255 scope global dynamic noprefixroute wlp58s0
       valid_lft 21466sec preferred_lft 21466sec
    inet6 2001:67c:1232:144:9f96:e9a0:3a6f:8de/64 scope global dynamic noprefixroute 
       valid_lft 2591966sec preferred_lft 2591966sec
    inet6 fe80::95ba:c96b:d420:7871/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

and I could use that connectivity to do my normal work.

I'm no longer in that room, but hopefully there is some useful data in the
report.

Thanks,

Ben
#1120 fixed intermittent WiFi at different places panda@… benno@…
Description
Hi, 

I experience intermittent WiFi at different places, e.g. at the cafe/bar on the mezzanine close to the IETF lounge entrance.  If I move to the IETF lounge, all WiFi is fine.  The signal at the cafe/bar is fine though, but I do see packet loss of about 25-75%.

Right now at the DPRIVE workshop in Hall III I also experience huge packet drop rates with ietf and eduroam SSID networks, both IPv4 and IPv6.  :-)

I use a MacBook Pro with macOS Sierra 10.12.5. 

Others doesn’t seem to see this large packet drop rate though.

Thanks,

— Benno
