Hi, clearly the firmware is crashing in your computer (wonder why). Do you have exactly the same chipset as me (lspci -nnk) ? 02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0041] (rev 20) Here are my outputs just FYI. I'm not sure why the firmware crashed in your box ("[ 3.584948] ath10k_pci 0000:02:00.0: firmware crashed! (uuid e628e267-4dee-4da1-8a51-ed236bd4fc19)", trying to look for the unsolicited fw crash interrupts). *-network description: Wireless interface product: Qualcomm Atheros vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlp2s0 version: 20 serial: f1:59:19:6f:94:3d width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath10k_pci driverversion=4.1.0-1-amd64 firmware=atheros-12.0.0.102-fw ip=10.1.1.4 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:49 memory:e4000000-e41fffff *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: enp3s0 version: 10 serial: 65:ff:88:4d:ca:71 size: 10Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:43 ioport:4000(size=256) memory:e4204000-e4204fff memory:e4200000-e4203fff 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp3s0: mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 65:ff:88:4d:ca:71 brd ff:ff:ff:ff:ff:ff 3: wlp2s0: mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000 link/ether f1:59:19:6f:94:3d brd ff:ff:ff:ff:ff:ff [ 5.866041] ath10k_pci 0000:02:00.0: pci irq msi-x interrupts 8 irq_mode 0 reset_mode 0 [ 6.056962] ath10k_pci 0000:02:00.0: firmware: failed to load ath10k/cal-pci-0000:02:00.0.bin (-2) [ 6.056963] ath10k_pci 0000:02:00.0: Direct firmware load for ath10k/cal-pci-0000:02:00.0.bin failed with error -2 [ 6.057265] ath10k_pci 0000:02:00.0: firmware: failed to load ath10k/QCA6174/hw2.1/board-pci-168c:0041:17aa:3545.bin (-2) [ 6.057266] ath10k_pci 0000:02:00.0: Direct firmware load for ath10k/QCA6174/hw2.1/board-pci-168c:0041:17aa:3545.bin failed with error -2 [ 6.057267] ath10k_pci 0000:02:00.0: failed to load spec board file, falling back to generic: -2 [ 6.057426] ath10k_pci 0000:02:00.0: firmware: direct-loading firmware ath10k/QCA6174/hw2.1/board.bin [ 6.059061] ath10k_pci 0000:02:00.0: firmware: direct-loading firmware ath10k/QCA6174/hw2.1/firmware-5.bin [ 7.251278] ath10k_pci 0000:02:00.0: qca6174 hw2.1 (0x05010000, 0x003405ff, 168c:0041:17aa:3545 fallback) fw atheros-12.0.0.102-fw api 5 htt-ver 3.25 wmi-op 4 htt-op 3 cal otp max-sta 32 features  [ 7.251282] ath10k_pci 0000:02:00.0: debug 1 debugfs 1 tracing 0 dfs 0 testmode 0 [ 7.329352] ath10k_pci 0000:02:00.0 wlp2s0: renamed from wlan0 [ 9.483580] ath10k_pci 0000:02:00.0: no channel configured; ignoring frame(s)!
