Description
Hi guys, I'm in the North Tower, 14th floor (room 1421, close to the elevator). For the last 3 evenings I'm seeing 30-50-70% packet loss on the network (ietf-hotel). ifconfig/netstat/ping to my default gateway attached (the file name "furry_ping.txt"). Wireless info (BSSID etc) in the attached file "furry_ietf_hotel_room_wifi". Data captured at ~19:40 local time today. I have a tcpdump output as well (but I can not see anything particularly interesting here), attached just in case ("furry-hotel-room.pcap"). Let me know if you need any other info. Thanks! -- SY, Jen Linkova aka Furry

Hi Jen,
The ietf-hotel SSID is being broadcast to the guest rooms over the hotel's wireless infrastructure. I suspect your guest room is not located close to one of the hotel access points and the poor signal quality (resulting in an MCS index 1) is affecting your wireless experience. This appears to be a classic case of an access point transmitting at high power (allowing you to see/hear it), but unable to adequately hear (receive) the transmissions from your radio. Unfortunately, there is little we can do other than suggesting you use the hard wired connection in your room or move to a room located closer to one of the hotel's access points.

Jen,
We've got the info we need and we'll work with the hotel to check if the guest room AP you're associating with is having trouble. As Rick mentioned, you may simply be in a bad coverage area, but we'll double check to make sure it's not an infrastructure issue.
Sorry for the delay on jumping on this...

Hi Jen,
The hotel just notified us that they identified and repaired a cabling problem to the access point you were associating to. Try to connect again and let us know if the problem has been resolved. I apologize for the delay in resolving this issue.
Thanks,
-Rick

The situation is slightly better now, but still far way from being ideal: --- 31.133.136.1 ping statistics --- 314 packets transmitted, 242 packets received, 22.9% packet loss round-trip min/avg/max/stddev = 2.216/10.436/95.776/9.231 ms --- 8.8.8.8 ping statistics --- 319 packets transmitted, 262 packets received, 17.9% packet loss round-trip min/avg/max/stddev = 8.445/19.409/289.705/28.016 ms Not sure if it's the same AP or not (BSSID and wireless-related other info attached). I'm flying tomorrow morning so will be using the network in my room for one more evening only. Probably spending time on tracking the issue down just is not worth it... I really appreciate your efforts! -- SY, Jen Linkova aka Furry

Hi Jen,
Based on the BSSID you reported you're connecting to a different AP. If you have a chance, please turn your Wi-Fi off and back on when you are in your room and see if that makes a difference. You may be holding on to a connection to a distant radio and not roaming effectively. Let me know if this makes a difference.
Thanks,
-Rick
