How to slow down an internet connection?

Im having some weird problems exclusive to users with slower or inconsistant internet connections.

any ideas on how i could intentionally slow down or imitate a shaky internet connection for testing pursposes to find and fix these errors?

I believe that is something that can be achieved on your router. Just go to router page and play around. But I also think this is a wrong forum for such quesitons

If it is a multiplayer game, go to Network Manager component and enable “Use Network Simulator”. Then play around with the settings.
