[Help!!!] How to limit bandwith "ON THE FLY"?

I have a user profile x and limited max speed download to 1m.
I have a user y that uses profile x.

While user y is online, I tried to change the limited speed of profile x, but nothing happens
unless user y got kick out of a session and login again.

Anyone knows how to change the speed on the user current active session?

Thx in adv for your help.

Users bandwidth limitations are queues created dynamically by RouterOS (see Queue in winbox or /queue simple). Those queues can’t be changed (at least, the queues created by Hotspot).
Maybe you can remove user Y’s queue and recreate it.. but it’s not clean, you will certainly have to remove it youself at the end of Y’s session. It depends of the typology of you users.

Thx for your reply my friend, appreciated. ^^
