Yes, I noticed the term ‘NTP’ in a side note from @Tux0ne at the beginning/mid of December and then, as I often do, I just gave it a try.
For me, activating and correctly setting NTP immediately solved the problem with reaching the email server. Together with deactivating the devices for the booster in the IB3 and deactivating/clearing the DNS cache, the booster integrated perfectly into my network. Since then (over 14 days) no more problems. The speed almost always close to 500/100 from original 100/30.
However, I don’t know - and won’t fiddle with it again - which of the 3 measures was decisive.
But @wolewo’s network topology is much more complex than mine and I hope he can solve the problems too. If it is actually “only” due to NTP, Swisscom would have to think about whether this function should be set up automatically when the booster is delivered/installed. If that’s even possible.
I suspect that the wrong time also has an influence on some systems.
There is also some good information below.

I’m currently using the speed test at the link below, and it still shows relatively correct values.
But you still have to adapt the corresponding Swisscom subscription, see the picture below, for example. Subscription “L” with 5G booster.

You can get the most extensive background information by testing the CNLAB app if you click on the user ID at the top right of the window after the test.
You can also get a lot of additional information from the official tester from the Swiss provider (Networktest) if you click on “Show measurement results” after the measurement.
Is that correct? You briefly disconnected the 5G booster from the power supply?
N.b. I can’t complain myself, it works without any ifs and buts, I just had to briefly disconnect the 5G booster from the power supply after a firmware update from the IB3.

My tip regarding NTP was more related to the problems with post 283 described by ebu.
Error with secured connection etc. Can occur, for example, if the time synchronization on the affected client is not correct.
If the NTP switch on the booster, which is deactivated by default, had an influence, it would be more of a coincidence or a conceptual problem with this booster story 🙂
