Re: disable software blocking of wifi?

[znavko]

As described here https://ubuntuforums.org/showthread.php?t=1781350&p=10942349#post10942349

need to do this:

sudo sh -c "echo 'options ath5k nohwcrypt' >/etc/modprobe.d/custom-wireless.conf"

So I tried this:

$ lsmod | grep ath
ath9k                 155648  0
ath9k_common           24576  1 ath9k
ath9k_hw              479232  2 ath9k_common,ath9k

cfg80211              692224  4 ath9k_common,ath9k,ath,mac80211
ath3k                  24576  0

# guix system reconfigure

# reboot

Also I have this in /var/log/messages :

Apr  5 16:56:40 localhost wpa_supplicant: Libgcrypt warning: missing initialization - please fix the application

I do not know what to do?

Hello! I am creating my own config. I've disabled networkmanager-service-type, configured wpa-supplicant (but have not yet configured dhcpcd, cause it needs networking service).

Guix reconfigures my system normally.

But during boot there is a message: rfkill: WLAN soft blocked

And that is why wpa-supplicant fails:

# reboot

# dhclient -v wlp2s0

# rfkill unblock wifi

# herd restart wpa-supplicant

# dhclient -v wlp2s0

So I need manually unblock wifi and restart wpa-supplicant, but it's not coveinent.

I tried this lines as I've got from here https://superuser.com/questions/819547/how-do-i-stop-rfkill-module-from-hardblocking-my-wifi-without-rfkill-command :

 (kernel-arguments '("modprobe.blacklist=pcspkr,snd_pcsp,wmi,pata_acpi"

                     "modprobe.options.rfkill.master_switch_mode=2"

                     "modprobe.options.rfkill.default_state=1"))

But adding 'wmi,pata_acpi  ' but not helped. If add ideapad_laptop to blacklist, then rfkill does not see interfaces wlan and bluetooth.

# lsmod | grep -e wmi -e acpi

wmi                    32768  1 ideapad_laptop

How to prevent rfkill blocking of wlan?
