When I swim on a server at Minecraft, I always glide and do not come forward. When I'm underwater, I can't get up. What to do?
Just go upstairs
I always glide down
That's up to your ping, your connection is too unstable and therefore you can't really play fluent.
What can I do against it?
Use LAN instead of WLAN or gain a more stable line.
Yes then just swim up
I can't swim up, because then I glide down again
