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
