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.
