Is your wireless slow?

Improving slow Wi‑Fi performance

If you’re seeing slow Wi‑Fi or unstable transfers, this guide helps you test whether Wi‑Fi power saving is the cause, and (if it is) disable it.

Star Labs devices typically use Intel AX200 / AX201 Wi‑Fi cards.

1) Quick test (temporary)

1. Open Terminal (Ctrl + Alt + T).
2. Run the command below (your interface name might be different):

sudo iwconfig wlp0s20f3 power off

If you get an error, first find your Wi‑Fi interface name:

iwconfig

Then re-run the command using the interface name you see (for example wlp0s12f0).

2) Optional: install a Wi‑Fi monitor (wavemon)

Ubuntu/Debian:

sudo apt update
sudo apt install wavemon

Fedora:

sudo dnf install wavemon

Arch/Manjaro:

sudo pacman -S wavemon

Run it with:

wavemon

3) Make it permanent (if the test helped)

Create a config file for the Intel Wi‑Fi driver:

echo "options iwlwifi power_save=off" | sudo tee /etc/modprobe.d/starlabs-wifi.conf

Apply it:

• Ubuntu/Debian:

sudo update-initramfs -u

• Fedora:

sudo dracut -f

• Arch/Manjaro:

sudo mkinitcpio -P

Then reboot.

Notes

• Some Linux kernels label AX201 as Wireless‑AC 9462. That can be normal.
• Turning off power saving can slightly increase power use.
