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 ` – JBDeVega Apr 09 '17 at 03:29
  • 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
