Hello list, I ma connected to my WPA2-PSK protected network and from time to time I get the following warning in dmesg. I don't experience any malfunctionng but I thought it was worth reporting. My kernel version is linux-3.10.10. I remember I've seen this warning also with previous versions.
The device I use is a TP-LINK TL-WN721N. lsusb says: Bus 002 Device 003: ID 0cf3:9271 Atheros Communications, Inc.
