I was trying to improve the wifi signal range, but when I executed the command sudo modprobe -rv rtl8723bemy wifi stopped working and I cannot do anything.

How I do reset the config or rollback this changes?

  • See this and then do cat wireless-info.txt | nc termbin.com 9999 and edit the question to add the URL. You have a messed up conf file somewhere – Jeremy31 Jul 08 '18 at 21:51
  • In terminal, what does modinfo rtl8723be show? – heynnema Jul 09 '18 at 01:12
  • @Jeremy31 why do you think so? My wifi stops working when I pull the driver out of the kernel too! – Zanna Jul 09 '18 at 20:00
  • @Zanna a reply about a modprobe rtl8723be in an answer I deleted was that the result was fatal, you can not insert rtl8723be – Jeremy31 Jul 09 '18 at 21:14
  • @Jeremy31 oh I see! That's not the real error message though, so maybe they just mistyped it. If it really doesn't work, the question is unclear, because everything implies the WiFi worked fine before running the command and that the command worked as expected – Zanna Jul 09 '18 at 21:30
  • @Zanna I suspect a conf file change before the modprobe -rv – Jeremy31 Jul 09 '18 at 21:35

The command sudo modprobe -rv rtl8723be removed the module from the running kernel (that's what the -r option does - it's short for --remove).

This doesn't alter any configuration, so the driver will be inserted again on the next boot. To insert it manually, run sudo modprobe rtl8723be (without the -r option). You don't need the -v option; it only makes the command's output more verbose. Also see man modprobe for more information.
