Find an internet provider that runs smoothly. Streaming up to 4k should not be a problem and should work without interference. I'm currently at 1und1 and there are always internet problems. I stream GeForce now, Google Stadia and Shadow.
Depends on your region
1und1 is only a reseller and uses Telekom Kabel.
the speed at your location is limited by the cable (Telekom) … No matter which provider.
You can't answer that because it depends on the conditions in your region. The best thing to do is to inquire around you.
So it doesn't matter which one I take, it always stays the same? I live in a city have 100k
I always go to the main provider, i.e. Telekom, Vodafone, O2 / E +
In the fixed network area / DSL I have been with Telekom and possibly for over 20 years, all the time about 5 days where something was not possible and the speed is always the same, I can't complain at all.
I'm also a mobile phone operator, I have never noticed that I have poor reception or bad internet, except for our work, but that is probably due to the bulletproof glass screen.
In addition, I also have a data contract with Vodafone, so I can't complain at all.
So when it comes to internet at home, I would recommend Telekom at any time, also because of the support.
you can even reach someone in the middle of the night on Sundays and public holidays
24/7
I don't know of any other provider
is a bit more expensive than most, but quality and service cost a little more
