Hi, Jes Sorry if you already received this feedback, I could not find references. I am trying a TP-LINK TL-WN821N wifi usb dongle with Realtek 8192cu (lsusb returns: 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter) and found the same problems described in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1365844 When using kernel rtl8192cu driver, I can connect to wifi, but soon the connection is dropped. Since some time ago (2014) you asked for feedback in that bug and I did not find further references I decided to try your rtl8xxxu driver. All tests were carried out in a Debian GNU/Linux jessie box (current stable release) with kernel 4.7.8 from Debian jessie backports (source package linux_4.7.8-1~bpo8+1.dsc). Changed kernel config to ## file: drivers/net/wireless/realtek/rtl8xxxu/Kconfig ## CONFIG_RTL8XXXU=m CONFIG_RTL8XXXU_UNTESTED=y built a kernel (slooow here), installed it and added this line to a file under /etc/modprobe.d alias usb:v0BDAp8178d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu If the dongle is initially connected, system loads the rtl8xxxu module instead of rtl8192cu when booting but seems not to initialize the dongle, so I have no connection. However, if I disconnect the dongle and reconnect it again with the system on, everything seems to work well with no connection dropping. Only minimally tested, but apart from the boot problem apparently much better than with the built-in rtl8192cu kernel module. Thanks for all the work you are putting into this driver -- Agustin
