hallo, sorry for not speaking in germany I just moved here.
So I have a pretty hight download and upload speed +200mb/+50mb, but most of the times if I'm on call on WhatsApp, FaceTime, Zoom I keep having this 10-15seconds of droppout where these services don't response and just unstable internet. also I'm playing games online its the same thing. the weird thing is when this happened and dropped out of the call I quickly go to do a speed test and results seems pretty fine. could this be a hardware problem (router)?
please help me I'm having this issues almost all the time during the day.
Danke
