Hi, Even if you have 20Mbps per client + SpeedBurst setting, it should not cause to limit the clients' throughput to only 1 Mbps. You can check the changelogs if there any other settings have been changed. ie. on the traffic shaping page, the client tracking option on the MX, and on the port settings of the switch connecting to the MX. If you face the issue again or if you are want to test it (putting the 20Mbps per client + SpeedBurst back), I recommend calling the Meraki support to help you with the checking as this is definitely not expected behavior. thanks,
