It's not what I thought. Does it help if you reload the driver?:

Code: Select all

 sudo modprobe -r wl && sudo modprobe wl && systemctl restart NetworkManager 

[mxshii]

no didn't fix it

First of all, I am using Linux mint xfce and I am new to linux so I installed the driver for wifi and i am facing some issues like when i download something the Internet slows down on every other device connected to the same wifi, except my pc because it is connected with ethernet cable.

I don't, but someone else might. I assume you tried restarting your router & machine?

[Hawaiihemd]

How is this a driver or hardware issue with this particular Mint machine?
If other devices(!) experience a slowdown over WiFi but your machine connected over Ethernet does not, then this sound to me like QoS prioritizing by your router.

[mxshii]

I don't, but someone else might. I assume you tried restarting your router & machine?

Yup tried everything nothing works, i think it's a driver issue because it used to work well on Windows alsoooo bad network bandwidth control on this wireless card

I mean it used to work on windows fine idk, any idea on how to fix it?

[sleeper12]

You can try a different driver:

Code: Select all

sudo apt remove bcmwl-kernel-source && sudo apt install firmware-b43-installer

Reboot

[JerryF]

When you say you installed the driver, were you having a problem with the wifi before you installed the driver?

Drivers are contained within the kernel, so it's rare that you have to install a driver.

Drivers are contained within the kernel, so it's rare that you have to install a driver.

I mean the driver wasn't installed so i had to install it from the driver manager, i was using ethernet to download the driver, when using ethernet there wasn't any problem no slow down, even downloading didn't affect it but after installing and using the wifi driver, using it normally to browse the Internet works fine doesn't slow down the Internet but when downloading anything the Internet slows down on every device

[mxshii]

You can try a different driver:

Code: Select all

sudo apt remove bcmwl-kernel-source && sudo apt install firmware-b43-installer

Reboot

still internet slows down
