Hi dear NOC team,

it seems I loose a lot of packets and have large latency when using 
ietf-hotel wifi from my hotel room (Alii tower floor 15, room 1514). 
When connecting in the conference centre terminal room, I have no problems.

As a quick illustration, here three pings I just did to a www, and one 
to a mail-server:

I hope you could help in any way?

Thanks a lot for all your good work making our IETF meetings happen and 
all the best,

Hello dear NOC team,

I seem to have a very bad connection on my Wifi access point in my room.
*My room number at the Hilton is 6098 (6th floor). *
I have a very weak signal, but even when connected to the Wifi 
(ietf-hotel), I get a huge variation in packet losses up to >90% and 
timeouts and the Internet is practically unusable in the room. 
(Sometimes, it works for a short while, before things degrade again...)

Below a quick dump of iwconfig for the Access point info.
(I use Linux, but the same situation is for my windows computer and my 
smartphones.)

IEEE 802.11abgn  ESSID:"ietf-hotel"
           Mode:Managed  Frequency:2.412 GHz  Access Point: 
24:C9:A1:6D:A6:C8
           Bit Rate=130 Mb/s   Tx-Power=22 dBm
           Retry  long limit:7   RTS thr:off   Fragment thr:off
           Power Management:of
           Link Quality=33/70  Signal level=-77 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:60  Invalid misc:1453   Missed beacon:0

There seems to be a second access point with slightly better connection 
in this area:
wlan0     IEEE 802.11abgn  ESSID:"ietf-hotel"
           Mode:Managed  Frequency:2.442 GHz  Access Point: 
24:C9:A1:6D:7E:A8
           Bit Rate=39 Mb/s   Tx-Power=22 dBm
           Retry  long limit:7   RTS thr:off   Fragment thr:off
           Power Management:off
           Link Quality=41/70  Signal level=-69 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:393  Invalid misc:56767   Missed beacon:0



Please advise or help to fix.
As at the moment, due to this problem I basically have no working 
Internet access in the room.

Thanks, Tobias

Nothing to do, just FYI for your information: The first 2-3 days the Wireless LAN seemed to drop a few times. (location: room Roma), with my mobile phone. After you put a AP into the Roma room, it seemed to have been fixed. Best regards and thanks a lot, Tobias
