I must revise my previous statement. It seems that Alexa devices may cause this issue. I connected a Reolink camera and Gruenbeck device over Wifi and a HuE Bridge over lan and the network runs fine. As soon as I add an Alexa device the ping goes up and start loosing frames on all networks. I tried an old Alexa dot and Alexa Show and they both show this behavior. The strange thing is that the Alxea devices run fine on the primary network and dont cause any issues there. Does anybody have an idea what could cause this?
