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

mac80211              839680  1 ath9k
cfg80211              692224  4 ath9k_common,ath9k,ath,mac80211
ath3k                  24576  0
bluetooth             561152  7 btrtl,btqca,btintel,hci_uart,btbcm,ath3k,btusb

                     "modprobe.options.ath9k=nohwcrypt"))

);;end of operating-system

# 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?
