I can confirm this is still a problem on 15.04: Distributor ID: Ubuntu Description: Ubuntu 15.04 Release: 15.04 Codename: vivid Linux craft 3.19.0-26-generic #27-Ubuntu SMP Tue Jul 28 18:27:31 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Plugging in an "EDIMAX EW-7811Un N150 USB 2.0 Wireless nano Adapter" using the rtl8192cu default driver leads to a working WiFi device which will connect to open networks but then silently fail after a few seconds or minutes. Following http://github.com/pvaret/rtl8192cu-fixes fixes the issue 100% as far as I can tell so far. (This was also the case for a Debian 8 Stretch install I tried it on, and IIRC, I also tried out the dongle on a 4.2x kernel fork I was compiling in order to get working ath10k/Atheros WiFi drivers and the dongle did not work by default there, so I guess it's still an issue upstream?) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1365844 Title: 0bda:8178 buggy driver rtl8192cu Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu 14.04/14.10 driver rtl8192cu for a Realtek USB wireless card is buggy. I can connect to wifi, but soon the connection is dropped. WORKAROUND: 1. First check whether the buggy driver rtl8192cu is active in your operating system. Execute at a terminal window: lsmod | grep rtl 2. Disconnect your wireless connection (unplug the USB adapter that contains the Realtek chipset), and temporarily connect to the internet by means of an ethernet cable (or by means of another wireless chipset that does function well). 3. Now install some applications for building the right driver via a terminal: sudo apt-get install linux-headers-generic build-essential dkms git 4. Now download the source code of the driver via a terminal: git clone https://github.com/pvaret/rtl8192cu-fixes.git 5. Set it up as a DKMS module via a terminal: sudo dkms add ./rtl8192cu-fixes 6. Build and install the new driver via a terminal: sudo dkms install 8192cu/1.9 7. Refresh the module list via a terminal: sudo depmod -a 8. Blacklist the faulty driver via a terminal: sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/ 9. Reboot your computer. The problem should now be solved: disconnect the temporary ethernet cable and insert the Realtek device again. With the following terminal command you can check whether the right driver is active now (copy and paste it into the terminal): lsmod | grep 8192 Note: a possibly surprising side effect might be, that the light on your wireless card is blinking constantly now. That's normal: the light is blinking whenever data are being sent or received.
