My mouse has terrible range from my computer. If it go too far, it disconnects. It has maybe a metre range.
I have openrazer with polychromatic installed.
Sometimes when my mouse is too far, the way to fix it is reclick the power button on the mouse.
The battery is almost full.
I’m on KDE as well if that helps.
Firmware bug?
AFAIK openrazer doesn’t provide firmware updates, so if it needs an update to fix something, you can’t update without razers software.
