What can you do if you have 100 ping (ms) on Switch on Fortnite?

I have a short problem and that is with my switch in the fortnite I always get a 100 ping what can I do that I can manage at least 10 pings

There's nothing you can do, at most use a LAN cable if you don't already have it

What can I do that I can manage at least 10 pings

well, with 100ms ping you have at least 10ms ping - that has already fulfilled your wish

In principle, this Can't be assessed over the Internet, you would have to know the whole situation on site.

You will have a certain basic ping to your provider, which you will not fall below - because the data first ends up there before it is distributed.

I strongly assume that you use the switch via WLAN. You could try a LAN adapter, this could possibly reduce the ping

First, I would check whether you have set the correct region. If this is correct, you can see how your ping is created. What is your ping to your own router and is it different between a cable connection and a Wi-Fi connection.

If there are no abnormalities either, you look for another provider or you live with the "problem".
