Hi: Currently i am using latest backport git and linux-stable git tag v4.13 to backport to my old linux4.2.8. I am successfully enable the ap mode(with hostapd). Then i bridge(by command brctl) the ap with wired port and i test connectivity with my cell phone and laptop. But unfortunately it stop at getting ip. Is there any hint for me to do next? Here is my dmesg log: [ 265.243823] Loading modules backported from Linux version v4.13.12-0-g0da7475 [ 265.251009] Backport generated by backports.git v4.14-rc2-1-27-g75fadbc [ 265.322001] DMAR: 32bit 0000:09:00.0 uses non-identity mapping [ 265.328015] ath10k_pci 0000:09:00.0: enabling device (0000 -> 0002) [ 265.334794] ath10k_pci 0000:09:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0 [ 265.384951] DMAR: 32bit 0000:0a:00.0 uses non-identity mapping [ 265.390950] ath10k_pci 0000:0a:00.0: enabling device (0000 -> 0002) [ 265.397700] ath10k_pci 0000:0a:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0 [ 265.438563] ath10k_pci 0000:09:00.0: qca9984/qca9994 hw1.0 target 0x01000000 chip_id 0x00000000 sub 168c:cafe [ 265.448575] ath10k_pci 0000:09:00.0: kconfig debug 1 debugfs 1 tracing 0 dfs 1 testmode 0 [ 265.457469] ath10k_pci 0000:09:00.0: firmware ver 10.4-3.4-00082 api 5 features no-p2p,mfp,peer-flow-ctrl,btcoex-param,allows-mesh-bcast crc32 f301de65 [ 265.501269] ath10k_pci 0000:0a:00.0: qca9984/qca9994 hw1.0 target 0x01000000 chip_id 0x00000000 sub 168c:cafe [ 265.511244] ath10k_pci 0000:0a:00.0: kconfig debug 1 debugfs 1 tracing 0 dfs 1 testmode 0 [ 265.520132] ath10k_pci 0000:0a:00.0: firmware ver 10.4-3.4-00082 api 5 features no-p2p,mfp,peer-flow-ctrl,btcoex-param,allows-mesh-bcast crc32 f301de65 [ 266.233865] flashcache flashcache_ioctl 21297 [ 266.238671] flashcache flashcache_ioctl 21297 [ 266.893232] ath10k_pci 0000:09:00.0: board_file api 2 bmi_id 0:1 crc32 751efba1 [ 266.956378] ath10k_pci 0000:0a:00.0: board_file api 2 bmi_id 0:2 crc32 751efba1 [ 269.668870] ath10k_pci 0000:09:00.0: htt-ver 2.2 wmi-op 6 htt-op 4 cal otp max-sta 512 raw 0 hwcrypto 1 [ 269.725879] ath10k_pci 0000:0a:00.0: htt-ver 2.2 wmi-op 6 htt-op 4 cal otp max-sta 512 raw 0 hwcrypto 1 [ 269.738776] ath: EEPROM regdomain: 0x0 [ 269.738783] ath: EEPROM indicates default country code should be used [ 269.738786] ath: doing EEPROM country->regdmn map search [ 269.738789] ath: country maps to regdmn code: 0x3a [ 269.738791] ath: Country alpha2 being used: US [ 269.738793] ath: Regpair used: 0x3a [ 269.787536] ath: EEPROM regdomain: 0x0 [ 269.787543] ath: EEPROM indicates default country code should be used [ 269.787546] ath: doing EEPROM country->regdmn map search [ 269.787548] ath: country maps to regdmn code: 0x3a [ 269.787551] ath: Country alpha2 being used: US [ 269.787553] ath: Regpair used: 0x3a [ 270.576232] ath10k_pci 0000:09:00.0 wifiap0: renamed from wlan0 [ 270.614875] ath10k_pci 0000:0a:00.0 wifiap1: renamed from wlan1 [ 282.787675] cgroup: docker-runc (29079) created nested cgroup for controller "memory" which has incomplete hierarchy support.
