GIGA CUBE Fortnite on the PC is it possible with LAN cable?

Moin I have a question, I read that one with GIGA CUBE everywhere
no online game can play with friends is it right? Or is that just for the consoles

The GigaCube gives you internet via LTE and that is not suitable for gaming.

GigaCube is an LTE router

Can go, but doesn't have to. Nobody can guarantee you

A friend of mine uses an LTE router from TP-Link and the network from Telekom via congstar and can at least play WoW without problems, but also netflix, amazon Prime or Joyn works without problems
It depends on the location of the next transmitter and how the supply is at the installation site

For me it is about the fact that I do not spit with friends jann e.g. Fortnite is that right?

No idea

Because I don't play Fortnite and don't know anyone else

However, I do not know what should speak against it
