I have install Elementary OS 5 Juno and i notice that wifi signal very weak even though still can connect to it and use it like normal. But sometime it will affect my work due to unstable signal.

I have tried to disable power management but it won't help much on getting better wifi signal.

any solution to this?

It is worth trying the solution described here. The video also shows a way of measuring the speed from Terminal, using speedtest. So, install and run speedtest to see the down/up speed before applying the solution:

sudo apt install speedtest-cli && speedtest

Now, in Terminal paste the following commands, one after the other:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlmvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

Run speedtest again and compare the results.

  • My wifi signal is weak but the speed quite high (not sure why). The speed is fast in 5ghz but after i run those command above, my speed limited to 30mbps or below. Why?
