Mouse Razer Atheris is lagging

Hi!
My mouse Atheris is weirdly lagging or disconecting from some time now... like if i move it around there are some miliseconds where it doesnt register movement, and if click just in those miliseconds of disconection, doesnt register any click either.

I use the 2.4 to usb connector.

any help or idea? i tried reinstaling synapsis and using another USB port.
