Hello, I have an rtl8192cu based USB WLAN dongle from D-Link, which works very unreliable for me. It is not directly recognized by my 3.18.7 linux kernel and I currently have > # cat /etc/modprobe.d/wlan-pmhahn.conf > install rtl8192cu /sbin/modprobe --ignore-install rtl8192cu $CMDLINE_OPTS ; echo "2001 330D" >/sys/bus/usb/drivers/rtl8192cu/new_id > options rtl8192cu swenc=1 I'm able to transmit some data, but normally after some time opening new TCP connections (especially SSL/TLS encrypted ones) fail. Ping on the other hand does not show any significant problems: > 953 packets transmitted, 950 received, 0% packet loss, time 953130ms > rtt min/avg/max/mdev = 43.433/75.560/457.843/34.281 ms dmesg shows this repeating pattern: > [ 132.185612] rtl8192cu: MAC auto ON okay!
