i recently had a issue that decreases my internet speed someone told me that i should use a proper driver so i saw a github page where they told to run this command modprobe -r b43 and more b43 in the line means my wifi driver so after that i didn't have internet so i ran another command modprobe b43 to get it re enabled it worked but after a reboot i have to run the same command to fix the issue also i tried insmod it gave me insmod: ERROR: could not insert module /usr/lib/modules/5.9.12-xanmod1/kernel/drivers/net/wireless/broadcom/b43/b43.ko: File exists so can someone tell me how to re enable it

DISCLAMER: i have a very bad english typing experience so please bare with me

  • See the output of `lsmod | grep b43`. I believe `File exists` means that module is already there. Probably you build another (bad) one and put it somewhere to the _/lib/modules/$VERSION/..._ (_extra_ or alike folder) and that's why you have loaded it instead of the system's one. – 0andriy Feb 17 '21 at 11:53
  • yeah but lsmod | grep b43 it dosn't show anything – Clerick X Feb 19 '21 at 14:23
  • and i used locate it showed /usr/lib/modules/5.9.12-xanmod1/kernel/drivers/net/wireless/broadcom/b43/b43.ko – Clerick X Feb 19 '21 at 14:24
  • also the file exists changed to Unknown symbol in module and when i enable it it goes back – Clerick X Feb 19 '21 at 14:28
