I'm having a Wi-Fi problem and it seems to be with the driver. Every now and then the Wi-Fi randomly drops and it act like I don't even have a Wi-Fi card in the computer. I found sudo service-network manager restart, works to get it back up. I am, however looking for a better solution and found 16.04 LTS wifi connection issues with Realtek RTL8723BE adapter.

The issue I keep incuring is every time I try to create any file in terminal I just get the message "no such file or directory". I'm trying to figure out what i need to do to actually make this work so I don't have to constantly open the terminal to reset the network manager manually. Below is my network card information. Removed serial for security reasons.

  • You get the "No such file or directory" error when attempting to add SUSPEND_MODULES="iwlwifi" to /etc/pm/config.d/config? please post the output of ls /etc/pm/* – Gansheim Apr 09 '17 at 03:04
  • `/etc/pm/config.d:

    /etc/pm/power.d:

    /etc/pm/sleep.d: 10_grub-common 10_unattended-upgrades-hibernate novatel_3g_suspend `

  • Okay so you should be able to create /etc/pm/config.d/config by running vim /etc/pm/config.d/config and adding SUSPEND_MODULES="iwlwifi". You can change vim to be your editor of choice such as nano. If you get the "No such file or directory" error again, make sure that you don't have any spelling or grammar mistakes in the path such extra spaces. – Gansheim Apr 09 '17 at 19:43
  • the vim solution just lets me open a file for editing in terminal but it doesnt seem to do anything beyond that. – JBDeVega Apr 11 '17 at 10:20
  • If you don't know the commands to edit documents with vim, I'd suggest you use nano instead (nano /etc/pm/config.d/config). – Gansheim Apr 11 '17 at 13:15
  • I was able to get the file made, however i still randomly lose wifi capability. – JBDeVega Apr 15 '17 at 09:36
