When I change the weapon, it changes with a little delay. Is it all due to the WLAN / Internet?
Yes, that's because of your internet connection
No, it has nothing to do with the internet.
Does it change directly on the slot or also with a delay? If the slot changes immediately, but the character hesitates, it is because of the internet or the servers. If it also changes with a delay, it may be due to the controller.
It changes to the slot directly and so the character hesitates on the Internet right?
Yes, it's either the internet or the servers.
Thanks
