Wifi not working for HP Probook 450 G4

I just bought my new Notebook Probook 450 G4. After I install the latest version of Archlinux, it seems everything working except the wifi, that's too annoying.
I run the lspci -v, it seems the system really detected the hardware as below:

03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
	Subsystem: Intel Corporation Dual Band Wireless-AC 7265
	Flags: bus master, fast devsel, latency 0, IRQ 131
	Memory at d3100000 (64-bit, non-prefetchable) [size=8K]
	Capabilities: <access denied>
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

And when I run dmesg, I saw following related info with regard to iwlwifi:

[   12.295411] iwlwifi 0000:03:00.0: enabling device (0000 -> 0002)
[   12.296291] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7265D-26.ucode failed with error -2

[   12.527586] iwlwifi 0000:03:00.0: L1 Enabled - LTR Enabled

I searched my system, the firmware do exist iwlwifi-7265D-27.ucode, but it seems kernel only search from iwlwifi-7265D-26.ucode, don't know whether this is the cause.

My current problem is, when I run comman "ip link", it output below:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether d0:57:7b:bb:cf:42 brd ff:ff:ff:ff:ff:ff
3: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether c8:d3:ff:dd:72:e7 brd ff:ff:ff:ff:ff:ff

Note the state of wlp3s0 is DOWN. I tried with command "ip link set wlp3s0 up", it returns no error, but when I type "ip link" to view the status, the state is always DOWN.
Does anyone know how to solve this issue?

By the way, currently BIOS seems do have some issue, during boot up, I saw some ACPI Error, like below:

But I guess this may not relate to wifi issue, since this seems to be ACPI issue.

Re: Wifi not working for HP Probook 450 G4

First, please edit your post and use BBCode code tags around program output, logs, and file contents.

The dmesg output shows that it did finally find the right firmware and it loaded:

[   12.341866] iwlwifi 0000:03:00.0: loaded firmware version 22.391740.0 op_mode iwlmvm

Your device is up:

wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP>

What is the output of:  sudo iw dev wlp3s0 scan   ?  (Be sure to use code tags, it may be long)

Re: Wifi not working for HP Probook 450 G4

Then for this output:

wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000

You mean the first "UP" means the device has been brought up? But what the second "DOWN" mean? Whether it should be "UP" when it's working?

Re: Wifi not working for HP Probook 450 G4

So, I can see that there are many access points near you.

	SSID: ChinaNet-eS6X
	SSID: PHICOMM_E7C7B4
	SSID: TP-LINK_242D
	SSID: qqjjyy
	SSID: TP-LINK_HyFi_7C
	SSID: 502
	SSID: huangjun
	SSID: TP-LINK_55B6EC
	SSID: w\xe2\x80\x86j\xe2\x80\x86q\xe2\x80\x86d\xe2\x80\x86w\xe2\x80\x86x\xe2\x80\x86lu
	SSID: TP-LINK_5592
	SSID: 
	SSID: TP-LINK_C76D02
	SSID: TP-LINK_6148
	SSID: jxy
	SSID: TP-LINK_302
	SSID: TP-LINK_YGH
	SSID: jiang
	SSID: TP-LINK_BD81
	SSID: @PHICOMM_10
	SSID: TP-LINK_402
	SSID: @PHICOMM_301
	SSID: TP-LINK_7360
	SSID: TP-LINK_F9FF
	SSID: wangjunjie
	SSID: ChinaNet-cgGy
	SSID: TP-LINK_111

I would say your WiFi is working fine.   What tools are you using to control your WiFi? (NetworkManager? systemd-network? netctl?)

The second 'DOWN' means that you are not connected to (associated with) anything.

Re: Wifi not working for HP Probook 450 G4

Thanks a lot. I misunderstood the state DOWN is similar to the Ethernet case which first need to use "ip link set" command to bring the state to UP, then try to configure the ip address.
I currently using the systemd-network to configure for both ethernet and wireless, but I do see it seems for wireless configuration the network manager is more suited and have more option, right?
I will do some further try, thanks again.

Sorry, my post did not apply. Same PC, but different wireless card.
