[solved] wifi hardblocked at boot

Hi,

I have a fresh BL installation on my HP (Compaq) 6910p laptop. Wifi is working, but when I reboot or wake it from sleep, wifi is completely disabled. It is hardblocked and softblocked, and pressing the touch-sensitive switch for the wireless device has no effect. I've discovered that I can unblock it with rfkill, but I then have to physically switch it on after it is unblocked.

This isn't a major problem, but it is very frustrating, because I've spent several hours trying to resolve what I thought was a simple problem. From what I've read, I believe the proper wifi driver is installed. If anyone has any thoughts about solutions I would be very grateful.

Below is a copy of my syslog over a ten minute period in which I shutdown with working wifi, restarted, then re-enabled wifi. I'm also including some of the customary data regarding installed drivers, modules, devices, etc. Thanks!

Re: [solved] wifi hardblocked at boot

rfkill can't unblock hard-blocked switches. I think what's going on here is that when you press the button on the laptop, the hard block gets removed and because you already removed the soft-block with rfkill, the wifi becomes available.

If your wifi hard-blocks after waking up from sleep or rebooting, then chances are high that your laptop's embedded controller (EC) is setting the hard block every time (given that there's no actually phyiscal on/off switch since the position of the hardware switch is apparently not being remembered when suspending/powering off the device). I suggest that you first look for an option related to the wifi switch in your computer's BIOS, maybe you can permanently remove the hard-block.

Re: [solved] wifi hardblocked at boot

hmm my gut instinct tells me it may have something to do with network manager, since it's the thing that handles changing of networking status... What's the output of :

nmcli connection show

nmcli device status

You can remove the devices from networkmanagers grip, by adding the wlan0 interface to /etc/network/interfaces  file.
This may stop networkmanager from stopping the nm from bringing the interface down.

I suggest that you first look for an option related to the wifi switch in your computer's BIOS, maybe you can permanently remove the hard-block.

Well, I rebooted, and did not touch the wifi power switch at all. I first checked to confirm the hard block:

$ sudo rfkill list all

	 0: phy0: Wireless LAN
		Soft blocked: no
		Hard blocked: yes
	1: hp-wifi: Wireless LAN
		Soft blocked: yes
		Hard blocked: no

I then entred 

sudo rfkill unblock all

, and the led light for wifi came on. I then double-checked with rfkill:

$ $ sudo rfkill list all
	0: phy0: Wireless LAN
		Soft blocked: no
		Hard blocked: no
	1: hp-wifi: Wireless LAN
		Soft blocked: no
		Hard blocked: no

I then followed your suggestion to check for a bios setting. There IS an option to disable wireless switching, which I selected. After rebooting there was no change in results. I confirmed the bios setting and repeated with the same result. Enabling switching again in bios did nothing. I'm stumped.

I tried both nmcli commands and got a 'command not found' error. I did an apt-cache search for nmcli and didn't find anything. I have a strong feeling that I'm doing something stupid. More stupid than my customary stupid.

Your comment about networkmanager issues got me thinking about connman, which I had installed. I thought maybe it could be conflicting with networkmanager in some way, so I disabled then uninstalled it. No change in results. I think set up wifi via systemd config files, etc., and disabled networkmanager service. No change, but resolving systemd errors resulting from a typo has been a good exercise in patience. I still don't have my network configuration files behaving well as the syslog shows an error  relating to RouteMetric in both wired and wireless config files:

Unknown lvalue 'RouteMetric' in section 'DHCP'

I triple-checked the content of the files but fail to see why they don't comply with the systemd documentation (and the examples from the archwiki). Here is my /etc/systemd/network/wireless.network file:

[Match]
Name=wlan0

[Network]
DHCP=both
DNS=8.8.8.8
DNS=8.8.4.4

[DHCP]
RouteMetric=512

I tried substituting different values (wireless higher than wired) but get no change. I will be tempted to buy a pre-configured linux rig to replace this thing when I finally snap and take out my frustrations on it. I may revert to network manager and reconfigure after taking a break.

As for isolating the wifi hard block problem, eliminating services has reduced the number of lines in my syslog:

Why have you set the RouteMetric so high?

These values work on my (Arch) system:
https://github.com/Head-on-a-Stick/conf … ed.network
https://github.com/Head-on-a-Stick/conf … ss.network

Does the connection still work as expected?

In  respect of @unklar's link, try adding hp-wmi on it's own line in /etc/modules and rebooting.

Re: [solved] wifi hardblocked at boot

Okay, I tried putting "hp_wmi" on its own line within /etc/modules as discussed in unklar's link with no result. Rather than take the time to find out how to change the order that modules are loaded, I decided to try blacklisting hp_wmi. Surprisingly (to me), this seems to work. I am able to reboot or wake from sleep with wifi already enabled. I'm a little confused, because modinfo indicates depends for this module (which I thought would prevent blacklisting of this module unless the depends were also blacklisted). Because I don't understand why this even works it feels like a bit of a kludge. I think I'll do some reading to better understand kernel modules.

Heh. I tried a number of different entries and couldn't even get a variation on the error message. I used your values to begin with (it turns out I was actually following your tutorial, which was nicely done by the way) but plugged-in some variations that I pulled from other sources. I just forgot to return it to something that looked more typical. I still don't know why I'm getting the error, though. I checked the official documentation, and it looks like it should work. By the way, I also got an error with the DHCP=ipv4 line. The documentation also listed that as a valid entry, but I found some commentary accompanying the commits, which suggested that they were discouraging "ipv4" and "ipv6" as entries; I have no idea why. Regardless, switching ipv4 to "both" resolved the issue (which was preventing connection). I guess I should add some articles on systemd to my reading list as well.

Thank you for your help with this; I really appreciate it.

Re: [solved] wifi hardblocked at boot

Good that my old nose still works.  big_smile

The loading of the "wrong" _wmi modules relates laptops from Acer, Asus, HP and Dell.

Symptom: the issue of rfkill list is a second wireless instance called "acer-wireless" to see.
