HelpHow do I prevent disconnection?

I need to know how to prevent disconnection of my client from the ROTMG servers.
When i change my weapon's ID into an ID that's not what i have equipped, i get disconnected a few seconds later.
I'm assuming i'm being disconnected due to the ID of the weapon being different from what the server thinks, so it disconnects the player.

EX: Client changes weapon to weapon 2 when it really has weapon 1, server gets confused and disconnects player.

Solution A: Get faster internet provider.
Solution B: Speed up your computer/client by reducing the quality and other lag related things.
(Capt-obv solutions)
Solution C: Use one weapon
Solution D: Quit RotMG :P

This can't be anything other than lag as a reason for the problem.

If it would be possible to prevent the disconnecting, rotmg wouldn't exist anymore.
