As the new QCA6174 Qualcomm Atheros Wifi/bluetooth (also known as QCNFA344) device is in use, I could not use Wifi with the usual Ubuntu 15.04 installation. Following https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184/comments/115 I compiled the new kernel with the ath10k driver and everything worked nicely at home with my Fritzbox 7490 router using the 5GHz band. At my parents place with a Fritzbox 3170 router I encounter the following problem. As soon as Ubuntu is connected to Wifi (using the 2,4 GHz band as there is no 5GHz band), other devices cannot connect to Wifi anymore. The ath10k driver blocks all other devices (Smartphones running Android, iPads) except for my personal laptop with a standard Ubuntu 14.10 system which can connect to Wifi for a couple of minutes before being disconnected as well. I can connect again but will loose the connection after a couple of minutes. I've also installed Windows 8.1 on the Acer Aspire, and if I connect to Wifi using Windows, these problems disappear, i.e. all other devices can also connect to Wifi without any problems. I've also not seen these problems at home which could be related to the fact that the Acer Aspire was using the 5GHz band while the other devices where using the 2,4GHz band. Running "cat /var/log/syslog | grep ath10k" after installation, I got 3 errors because of missing firmware: /lib/firmware/ath10k/QCA6174/hw2.1/board-pci-168c:003e:105b:e08e.bin /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin lib/firmware/ath10k/cal-pci-0000:03:00.0.bin The first two messages disappeared after running sudo cp board.bin board-pci-168c:003e:105b:e08e.bin sudo cp firmware-4.bin firmware-5.bin in the /lib/firmware/ath10k/QCA6174/hw2.1-directory. I could even delete board.bin and firmware-4.bin without loosing Wifi connectivity. At the moment these files are still there, but seem to be useless. Nevertheless "modinfo ath10k_pci" shows that only board.bin and firmware-4.bin from the hw2.1-directory are used. Very strange! I use the firmware extracted from my Windows installation using firmware provided by Acer's support page. Any help would be appreciated! Best wishes, Sven PS: Bluetooth is still not working even though its turned on and shown as active. But I can't send or receive files. _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
