I'm also having a similar issues, I have a xps 9360 with the killer 1535 board running on ubuntu 16.10. The weird part with my case is that I'm unable to make new requests while the existing ones keep working fine (like a download or a hangouts/skype call, they never drop).
Example, when browsing a website, the main page load, but the images from a CDN not. Its very similar to a DNS problem, but I tried google and open DNS without success. Also, I tested with my other computers and devices and they are all working fine. Another example is with music streaming, that fails only when changing the music file. I already did the fix suggested by #22, and also updated my linux- firmware to 1.163 (http://mirrors.kernel.org/ubuntu/pool/main/l/linux- firmware/) Anyone had similar problems? Would ubuntu 16.04 work better to me? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1520343 Title: Qualcomm Atheros wireless card [168c:003e] (rev 32) not supported Status in linux-firmware package in Ubuntu: Confirmed Bug description: --------------------------------------------------------------- STATUS 2016-03-17: ========== WARNING: You need at least kernel 4.5.0 for the following new fix to work, else refer to the old method described in post #22 ========== The support for this card has now been merged to https://github.com/kvalo/ath10k-firmware. 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. I suspect this card needs a new firmware in ath10k? --- ApportVersion: 2.19.2-0ubuntu6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dennis 1230 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=bed7757a-3749-4efb-9e9f-0ce8129bfbb9 InstallationDate: Installed on 2015-11-11 (15 days ago) InstallationMedia: Ubuntu-GNOME 16.04 LTS "Xenial Xerus" - Alpha amd64 (20151110) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 04f2:b520 Chicony Electronics Co., Ltd Bus 001 Device 002: ID 04ca:3016 Lite-On Technology Corp.
