This is swiped from reddit but I thought it was really helpful so please don’t judge me too harshly lol.
So it turns out that some Linux distros don’t enable this by default for whatever reason but if you have an Intel wifi card that uses the iwlwifi driver (you can check this with lspci -k
and look for a section that says Network controller: Intel Corporation
and Kernel driver in use: iwlwifi
under it), you can add a simple line to a config file that might make a huge difference to your wifi speeds.
Just edit /etc/modprobe.d/iwlwifi.conf
(if it doesn’t exist just create it) and add the line: options iwlwifi 11n_disable=8
then reboot. I ran Speedtest before and after trying this on my laptop and it seems to have increased it by about 20% or so.
Your mileage may vary of course, but hopefully this helps someone!
Please do a little research before trying random stuff. After checking to see if you are actually using the iwlwifi module, why not find out a bit about whether the mentioned param. is available to you and what it does:
Am I using the module. If the output from this is blank, then no:
Also verify with lspci -k as above:
sysfs is a pseudo filesystem with lots of info in it. cat the files here:
… to see what your current values are set at. You can install sysfstools and run this for a neat report:
