Hi,

I have constant connection issues.

When there's connection all speedtests seem to be fine, but I cannot participate in any calls or video calls, because the audio/video drops every 5s.

I checked multiple ping tests as well, most of them showed that everything is fine, but there was one where I show 4000ms spikes every 6s.

I have a Speedport Smart4, firmware is up-to-date, I have tried restarting it multiple times (through it's admin interface and by unplugging it as well).

I have also reported the issue, but unfortunately when the support called me I was not at home. Ironically I cannot stay home if there's no stable internet, because I need it for work :)

I have also tried to call customer support, but after a while I got lost trying to answer the questions.

How could I have this issue resolved?

Thanks,

Tom
