Ping probe always returns 0ms

Hi again!

I’m experiencing a problem with the standard ping probe that comes with the Dude: all the devices on my map return and graph a value of 0! Most of them really have response times <1ms as I rechecked with the ping tool in the Dude. But also the google DNS (8.8.8.:sunglasses: that returns about 16ms in the ping tool shows 0ms in it’s graph. Does anybody have an idea what is wrong with my ping graphs?

thank you AGAIIIIIN!
