Andriy is figuring it out with you :) It sounds like it's a key
programming thing?

I created the bug report for this 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=215265 since there is 
no known solution.

works fine with some wifi networks, but periodically loses connection on other
networks. Pings to the local router get lost while ifconfig shows that device
stays up and running.

doesn't print anything at the moment of failure and later.
TKIP is used in both observed working and failing networks.

There is some factor in some wifi networks that causes failures which isn't
obvious. I mostly observed successful work on the networks where I was the only
or major user so this may be the factor, or this may as well be coincidental.

Looks like it does not like CCMP + TKIP combination (or just TKIP?).

Can you check it with TKIP (pair) + TKIP (group) AP ?

Today I stumbled upon another network that fails with the same symptom,  
loss of IP connectivity. Nothing new is printed at and after the moment  
of failure, see below.

TP-Link TL-WDN3200 device periodically loses connection on some networks

[Yuri]

This device

ugen3.2: <802.11 n WLAN Ralink> at usbus3, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=ON (450mA)


TP-Link  TL-WDN3200  idVendor = 0x148f   idProduct = 0x5572

works fine with my home router, but periodically loses connection on 
other networks. For example, I lost connection about 5 times during the 
day. Pings to the local router get lost while ifconfig says that device 
stays up and running:


wlan0: flags=8843 metric 0 mtu 1500
ether XX:XX:XX:XX:XX:XX
inet 10.1.0.216 netmask 0xfc00 broadcast 10.1.3.255
nd6 options=29
media: IEEE 802.11 Wireless Ethernet OFDM/6Mbps mode 11a
status: associated
ssid "Xxx Hotel" channel 44 (5220 MHz 11a) bssid 
28:XX:XX:XX:XX:XX
regdomain FCC country US authmode OPEN privacy OFF txpower 17 
bmiss 7

mcastrate 6 mgmtrate 6 scanvalid 60 wme roaming MANUAL
groups: wlan


This ssid had about 8 bssids, and a lot of people were using it at the 
same time, if congestion matters.
