Device name Dell Inspiron N4010

PopOs and Windows 7 gave me 6 megabytes/s speed but fedora gives 100-200 kilobytes/s

… doing what?

What’s your network adapter?

doing anything even browsing internet is extremely slow
how do i check what network adapter I have (I’m using wifi)? dell’s website doesn’t give the exact name here is the official documentation https://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_inspiron_laptop/inspiron-14r_setup%20guide_en-us.pdf

I think it must be one of these https://www.dell.com/support/home/en-in/product-support/product/inspiron-14r/drivers since they provide the drivers for these

from command line, execute:

lspci

or:

lspci | egrep -i --color 'network|ethernet|wireless|wi-fi'

or

sudo dnf -y install lshw
sudo lshw -class network

I used the second command and this is the output

$ lspci | egrep -i --color 'network|ethernet|wireless|wi-fi'

I got it working!

I searched for the Broadcom whatever and found other people also had similar issue, so I figured it must be a non-free or something driver there was also a person asking in the ask fedora page how to download broadcom-wl driver so I downloaded that, did a reboot and now it works in full speed

sudo dnf install broadcom-wl

There you go. That was quite easy, wasn’t it?!

Please, next time when you paste output from the command line, paste is preformatted text using the button </> from the little toolbar. That way it looks much nicer and can much more easily read. I have done it for you now, just to see how it should look like, feel free to edit the text and see what I did using backticks (`)
