* ath20k blocks other devices @ 2015-05-15 10:07 Brummfax 2015-05-15 10:25 ` Michal Kazior 0 siblings, 1 reply; 9+ messages in thread From: Brummfax @ 2015-05-15 10:07 UTC (permalink / raw) To: ath10k Hi everybody, I bought a new Acer Aspire VN7-571G for my parents. 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 ^ permalink raw reply [flat|nested] 9+ messages in thread

Can you get some sniff logs and possibly wpa_supplicant verbose logs from, e.g. another linux-based client? At this point I don't have any data to draw conclusions from. Is the network encrypted? Can you try seeing if open network also yields the same behaviour? Logs/traces from ath10k client itself would be also helpful. You can read more about getting these here: https://wireless.wiki.kernel.org/en/users/drivers/ath10k/debug#tracing > 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.

There's a slight bug in firmware file advertisement in ath10k_pci hence modinfo tells you firmware-4.bin is the latest support for qca6174 while firmware-5.bin for qca988x. This is incorrect - both chips support firmware-5.bin in the ath10k git master branch. ath10k tries to load newer firmware binaries first and falls back to older. Nothing to worry about now though.

All this starting when the first one was not connected to my wireless AP, then I connect it and wait until two other devices lose their connection.
