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:

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