Enabling Antenna Aggregation Might Make Big Difference If Your Laptop Has An Intel Wifi Card. (lemmy.ml)

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!

My Wi-Fi bands are saturated with about 50 networks on 2.4 in an apartment complex.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
