How to disable wifi power save to prevent disconnects

I saw some posts about how weak the wifi is, and indeed it is… It kept losing signal and closing my ssh so I decided to try an old trick of mine. (Which happens to be an issue in all the Single Board Computers i have tried)

Since I disabled the chipset power saving mode I haven´t had disconnects, so It might be useful to you.


iw wlan0 set power_save off

I have to add that not only doesn´t disconnect anymore but it increased the speed of transfering files too.

Note:

This is not permanent, on reboot it gets restored to “on”

How to set it on boot.

To set it to off on boot you need to create the following scrip in:


/etc/network/if-up.d/powesave_off

#! /bin/sh  
set -e  
# Don't bother for loopback if [ "$IFACE" = lo ]; then         
exit 0 
fi  
# Only run from ifup. if [ "$MODE" != start ]; then         
exit 0 
fi  
# Only do it once (skip for inet6). if [ "$ADDRFAM" != inet ]; then         
exit 0 
fi  
/sbin/iw dev wlan0 set power_save off  
exit 0

And don´t forget to set exec permissions:


chmod +x /etc/network/if-up.d/powersave_off (or whatever name you put to it)

Nice sharing. The article advises disabling Wi‑Fi power-saving mode on Clockwork‑powered devices to resolve frequent disconnections and slow transfers. By running iw wlan0 set power_save off, users reported stable connections and improved speeds. To make it permanent, create and enable an executable script (/etc/network/if-up.d/powersave_off) that runs the command at boot. Struggling with your coding tasks?

Experiencing WiFi disconnects? This guide helps disable power saving mode. I noticed similar connection issues while engrossed in Pokerogue , especially when checking the Pokerogue Dex for optimal team builds. The command iw wlan0 set power_save off improved stability and transfer speeds for me. Remember, it resets on reboot, so follow the instructions to automate it. Hopefully, this helps you stay connected!
