Tried current workaround like is written in section "STATUS 2016-03-17:" of the description on the Ubuntu 15.10 Acer v3-372-582Z with kernel 4.2.0-34-generic. After reboot network manager icon in the status bar disappeared, wired is working, wireless is found in network section of the system settings with no networks displayed.

The repository now contains the required board.bin, board-2.bin and firmware-4.bin files for the card to initialize and connect to a bgn-access point (5GHz (ac- protocol) is still untested, feel free to modify this if you can confirm it works).

This bug is unique to revision 32 of the card [168c:003e], fixes for older revisions don't seem to work. There are a couple of issues regarding the fix for some people (not all): 1. Wireless works, but network throughput stops some time after connecting to access point 2. Bluetooth communications take a noticeable performance hit when transferring something over WiFi --------------------------------------------------------------- Original description: I have recently installed Ubuntu 15.10 (64-bit) alongside Windows 10 on an Acer Aspire VN7-792G-76ZH and discovered, that the Qualcomm wireless card doesn't work in it or 16.04. The card has the device id 168c:003e as many other cards, for example the Qualcomm Atheros Killer (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184), but it has a newer revision number (32) and the suggested fixes work only partially and the wireless is unusable. The computer has just been released this summer and is Intel Skylake -based. I've tried the patch from bug 1383184, which has a fix for the card revision 20: Make the directory /lib/firmware/ath10k/QCA6174/hw3.0/ and put in the patch files: board.bin firmware-4.bin notice_ath10k_firmware-4.txt ath10k_pci succeeds in loading the firmware, but it seems that the firmware is not working correctly: dmesg | grep ath [ 5.452683] ath10k_pci 0000:07:00.0: pci irq msi-x interrupts 8 irq_mode 0 reset_mode 0 [ 5.678420] ath10k_pci 0000:07:00.0: Direct firmware load for ath10k/cal-pci-0000:07:00.0.bin failed with error -2 [ 5.678773] ath10k_pci 0000:07:00.0: Direct firmware load for ath10k/QCA6174/hw3.0/board-pci-168c:003e:11ad:0807.bin failed with error -2 [ 5.678781] ath10k_pci 0000:07:00.0: failed to load spec board file, falling back to generic: -2 [ 5.679445] ath10k_pci 0000:07:00.0: Direct firmware load for ath10k/QCA6174/hw3.0/firmware-5.bin failed with error -2 [ 5.679453] ath10k_pci 0000:07:00.0: could not fetch firmware file 'ath10k/QCA6174/hw3.0/firmware-5.bin': -2 [ 7.802316] ath10k_pci 0000:07:00.0: qca6174 hw3.2 (0x05030000, 0x00340aff, 168c:003e:11ad:0807 fallback) fw WLAN.RM.2.0-00180-QCARMSWPZ-1 api 4 htt 3.26 wmi 4 cal otp max_sta 32 [ 7.802329] ath10k_pci 0000:07:00.0: debug 0 debugfs 1 tracing 1 dfs 0 testmode 0 [ 8.200607] ath: EEPROM regdomain: 0x6c [ 8.200614] ath: EEPROM indicates we should expect a direct regpair map [ 8.200619] ath: Country alpha2 being used: 00 [ 8.200621] ath: Regpair used: 0x6c [ 8.216605] ath10k_pci 0000:07:00.0 wlp7s0: renamed from wlan0 [ 13.462029] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 16.461416] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 24.760062] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 27.759534] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 36.046205] ath10k_pci 0000:07:00.0: failed to set arp ac override parameter: -11 [ 39.045729] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 47.344304] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 50.343794] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 58.630534] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 61.629936] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 69.920624] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 72.920132] ath10k_pci 0000:07:00.0: could not suspend target (-11) [ 81.206812] ath10k_pci 0000:07:00.0: failed to enable dynamic BW: -11 [ 84.206218] ath10k_pci 0000:07:00.0: could not suspend target (-11) ... Then it just constantly prints the last two messages on and on. I can weirdly enough see the card in iwconfig: wlp7s0 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off And I can see the wireless-icon in the toolbar, but scanning for access points or trying to connect to one doesn't work. This is the furthest I've gotten.
