Do you have a static network configuration? You should not use dhcp, make sure that your IPv4 and IPv6 address are configured as static. You should also have a look for netcups recommendations for IPv6 configuration --> https://www.netcup-wiki.de/wik…nd_Ubuntu_.28bis_17.04.29 (its german, you may have to use a translator like deepl)
Which OS do you use?
I am using Debian will do what you suggested see will keep an eye if it helps, thanks for the suggestion.
It's not misleading at all, no CPU runs at turbo frequency on all cores all the time. That's why it says "max. 3.9 GHz per core", not "3.9 GHz per core."
KVM in the product description also tells you that this is virtualized hardware with limited control over the metal.
Its all good, i never blamed netcup for misleading.
Just asked why do they say max 3.9ghz, and i got a pretty decent explanation.
