Hi,
thx. I missed that one.
Hmm they recommend a different Wifi driver.
+ fix the frequency of the cpu
+ some people use different codecs

I will play around alittle.
I hope the codec is the culprit.
Thats what messes up the SIP call with Jitsi.

Not sure if the driver is still save to use since its probably based on a outdatet kernel
