For the records, I am having this very same problem with e TP-Link TL- WN821N, shipped with a rtl8192cu chipset.
I have recompiled the kernel enabling Jes Sorensen driver, ## file: drivers/net/wireless/realtek/rtl8xxxu/Kconfig ## CONFIG_RTL8XXXU=m CONFIG_RTL8XXXU_UNTESTED=y 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 module 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, no connection dropping. Only minimally tested, but apart from the boot problem apparently much better that with the built-in rtl8192cu kernel module. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365844 Title: 0bda:8178 buggy driver rtl8192cu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1365844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
