беспроводное соединение и плата NIC не распознаны, и не возвращается, пока я не перезагружаю, даже если я перезапускаю администратора сети

Мое беспроводное соединение полностью исчезает и не распознано наряду с моей платой NIC и не возвращается, пока я не перезагружаю, даже если я перезапускаю администратора сети.

Шаги:

1) I boot up type in sudo iwconfig wlp3s0 power off (turn off power management)

2) 
$ iwconfig
enp4s0f2  no wireless extensions.

lo        no wireless extensions.

wlp3s0    IEEE 802.11  ESSID:"2.4ghz"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: E0:3F:29:93:3F:20   
          Bit Rate=144.4 Mb/s   Tx-Power=22 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=60/70  Signal level=-50 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:55   Missed beacon:0

3) I loose wifi using 5ghz or 2.4ghz after a certain amount of time

4) sudo rmmod iwlmvm iwlwifi && sudo modprobe iwlmvm iwlwifi
5) sudo systemctl restart network-manager.service

Я делаю iwconfig, и я пропускаю wlp3s0 IEEE 802.11 ESSID: "2.4 ГГц"

$ iwconfig
enp4s0f2  no wireless extensions.

lo        no wireless extensions.

Я должен перезагрузить для возвращения моего Wi-Fi, как я могу предотвратить это.
